DISCOVERY & INNOVATION
  BREAKDOWN OF MS RESEARCH
  The MS Society has funded research in multiple sclerosis since the first grant of $10,000
  was awarded in 1949. It is now, along with its affiliated MS Scientific Research Foundation,
  the single largest funder of MS research in Canada. Through the administration of operating
  grants, studentship awards, postdoctoral fellowships, career development awards, targeted
  research grants, and multi-site collaborative team grants, the MS Society and MS Scientific
  Research Foundation are committed to advancing research that investigates all aspects of
  multiple sclerosis, and fostering a strong network of talented researchers and trainees
  across the country. Investing in this research network also leads to increased national and
  international collaboration, facilitation of translation of new discoveries into treatments,
  and ongoing scientific training.

CULTIVATING A NEW GENERATION
                                  OF TOP MS RESEARCHERS
    The MS Society invests in the next generation of MS research leaders by
    supporting promising young investigators with a range of trainee awards and
    through education and training programs.

OPERATING GRANTS
The operating grant program is intended to support the generation of new scientific
knowledge and applications that will improve health and quality of life of people affected
by MS. These investigator-initiated research proposals must demonstrate relevance to MS
and pertain to the biomedical or clinical and population health research streams.

endMS STUDENTSHIP AWARDS
These awards are a key plank of the MS Society’s research training program. They support
talented students enrolled in graduate school who are keen on developing their knowledge
and research skills in MS.

endMS POSTDOCTORAL FELLOWSHIPS
Following completion of their graduate studies, postdoctoral fellows are intent on building
their research career and applying what they have learned to solve complex research
questions. The MS Society’s postdoctoral fellowship awards help to retain promising
trainees in the MS field by providing them with support during an important time of growth
and transition.

endMS CONFERENCE
The largest MS-focused scientific conference in Canada, aimed at fostering knowledge
exchange on MS-related research, networking opportunities, and collaboration among
researchers and trainees. Last year, the endMS conference was held from December 6-9 in
Toronto, ON. The conference included four sessions focused on different themes (cognition
and behavior, neuroimmunology, repair and neuroprotection, and progressive MS), the
HEAR MS day which was dedicated to building and strengthening connections between
trainees and people affected by MS, as well as poster presentations which allowed
researchers to interact one-on-one with their scientific peers to share their study and
gather feedback on advancing their research. The next endMS Conference will be held in
2019.

                                                                                   2

Impact of IL-27 on MS pathobiology
The role of the immune system is to protect us from invading microbes, but in MS,
malfunctions in the system cause inflammation and attacks on parts of the brain as if they
were foreign invaders. Dr. Nathalie Arbour’s research aims to identify molecules present in
the brains of people living with MS that are used by the immune system to attack it. Her
research is specifically looking at a molecule called IL-27, which has previously shown to
block inflammation. She wants to examine if the quantity of IL-27 present in individuals with
MS is a good indicator of the disease activity as well as the type of MS. So far, she has shown
evidence that IL-27 triggers different responses in white blood cells from people with MS
compared to those from healthy individuals. Dr. Arbour’s research project will also dissect
the effects of IL-27 on astrocytes, which are called the “house-keeping” cells of the brain.
This research potentially offers a new target in the pathophysiology of MS as well as may led
to development of novel biomarkers in the disease.

Role and therapeutic potential of Neuregulin-1 as a modulator
of neuroinflammation and remyelination in multiple sclerosis
Loss of or damage to myelin, the protective covering over nerve fibers, is one of the more
well-known characteristics of MS. Dr. Karimi’s research team has identified a protein called
Neuregulin-1 which is important for the development of oligodendrocytes, the myelin-
producing cells. Neuregulin-1 is significantly reduced in MS lesions and can be a cause for
failure in myelin repair. Increasing Neuregulin-1 is theorised to enhance oligodendrocyte
replacement, protect nerve fibers, and reduce scar formation. Dr. Karimi’s project will
determine the role of Neuregulin-1 in demyelination and neurodegeneration using animals
that have an MS-like disease. To perform this research, both genetic and pharmacological
approaches will be used to reduce or enhance the activity of neuregulin-1. As many of the
current MS therapies work by suppressing the immune response, there is a need to identify
effective therapies that specifically repair and renew damaged myelin. Dr. Karimi’s research
team hopes to identify neuregulin-1 as a potential target of the repair process of myelin.

Identifying New Molecular Mechanisms that Promote
Myelin Maintenance and Remyelination
Myelin is the protective covering produced by cells called oligodendrocytes which surround
nerve fibers. Dr. Kennedy studies the pathways of repair in the brain, in particular the
connections between oligodendrocytes and nerve fibers. He has previously found that a
protein called netrin-1 plays an important role in myelin production and repair processes. His
group is working to understand how netrin-1 contributes to the initial formation and
maintenance of myelin during development, and in the adult brain, and how targeting the
function of these proteins may promote remyelination. MS is a result of both damage to
myelin as well as a poor repair response. By figuring out the repair process down to the very
last detail, in particular the role netrin-1 plays, Dr. Kennedy and his team may enable the
development of treatments that enhance repair in people with MS, which is a vital step in
preventing further damage, slowing disease progression and allowing people to regain
neurological function.

Examining sex differences in neuropathic pain behaviours
in the EAE model
Pain is a major component of MS; it is estimated that over 50% of people living with MS
experience chronic, neuropathic pain. Dr. Bradley Kerr’s previous MS Society-funded research
determined differences in pain between sexes in mice with MS-like disease. His research
team also reported that differences in pain sensitivity can be impacted by daily exercise.
Using the results of his previously funded research project, Dr. Kerr plans to explore if pain
sensitivity can be modulated with an anti-inflammatory treatment of MS and if different
responses are seen in male and female mice with MS-like disease. Furthermore, Dr. Kerr
research plans to explore if oxidative stress, a process that causes neurodegeneration in MS,
is altered between different sexes and hence is contributing to different pain sensitivities in
MS. His goal is to generate important insights into the mechanisms underlying pain in MS,
which will pave the way for more effective therapies.

MicroRNA-145 is a key regulator of oligodendrocytes
maturation and CNS myelination
Dr. Rashmi Kothary’s research team is looking deep into the genetic code of oligodendrocytes
– the myelin-producing cells in the brain - to see if there are any important clues that will
reveal why myelin repair is inefficient or blocked in people with MS. His findings to date
revealed an increase in expression of a genetic molecule, MiR-145, in MS lesions. His
research’s team plans to test if increasing and decreasing the quantity of MiR-145 in both a
cellular and animal model of MS-like disease will be beneficial or detrimental in the
progression of MS. Dr. Kothary hopes that the findings from these studies will have an impact
on the development of future therapeutic strategies targeting myelin repair, which is crucial
in MS.

Elucidating the role and regulation of
astrocytes in multiple sclerosis.
A protein known as Cystatin C is elevated in people with MS but its function remains unknown.
Dr. Shalina Ousman and her research team discovered that Cystatin C is also increased and
plays a detrimental role in mouse models of MS-like disease and is expressed in the house-
keeping cells of the brain called astrocytes. Dr. Ousman’s current research aims to determine
if Cystatin C has a detrimental role through its regulation of astrocytes and if this in turn is
altering the immune response seen in MS. This work will provide a better understanding of
the pathophysiology of the MS disease and could lead to a new therapeutic target in MS.

Investigating a novel inhibitory signaling mechanism that
represses T cell-driven CNS autoimmunity
Loss of myelin contributes to MS disease. Dr. Rangachari’s goal is to identify genes that can
lessen the immune cell’s attack on myelin. His research team has already found a specific
gene called Serpine1 reduces damage to the myelin caused by the harmful T cells from the
immune system in an animal that mimics MS disease. The goal of the current research
project is to further delineate how Serpine1 works in MS. As MS is a disease caused by both
the immune and nervous systems, the research team will also determine which system
Serpine exhibiting its benefit on. A current approved MS drug called fingolimod (Gilenya) is
suggested to turn on the expression of Serpine1 and this might explain how fingolimod
improves MS. Dr. Rangachari’s research team plans to understand this process further.

Gait parameters as predictors of functional recovery
in a mouse model of MS
At least nine different types of drugs have been shown to stimulate remyelination and reduce
motor deficits in mice. Dr. Robertson’s aims to determine which of the nine drugs are most
likely to improve mobility of MS patients by stimulating myelin repair. To evaluate this, the
research team will use a method called kinematic gait analyses. Gait analysis observes the
complex joint movements of a leg that occur during walking into specific parts. For example,
improved ankle movement during walking is closely linked with increased myelin repair. This
technique will be used to determine which of the 9 drugs best improves the leg movements in
animal models of MS. Dr. Robertson hopes to establish a sensitive analytic tool of movement
analysis for selecting the most promising therapeutic compounds for human testing that will
improve the mobility in individuals with MS.

Characterizing the anti-inflammatory and disease-modifying
potential of novel a7 nicotinic acetylcholine receptor silent agonist
Nicotine has been shown to be protective against disease in mice that have MS-like symptoms.
The beneficial effect of pure nicotine is not to be confused with smoking, which aggravates
MS due to many other chemicals found in cigarette smoke. Dr. Simard’s project plans to test
new molecules that were recently created to recapitulate nicotine’s effect on immune cells,
thereby avoiding the side effects of less specific compounds. These molecules have very
potent anti-inflammatory properties and may be promising disease-modifying drug
candidates. The objective of the project is to understand if these novel molecules inhibit
inflammation, and whether these insights can be applied to all forms of MS.

A multi-site randomized controlled trial of MS INFoRM: An
interactive fatigue management resource for persons with MS
Nearly two-thirds of people with MS experience fatigue, which can negatively impact
employment, quality of life, and ability to engage in a full range of daily activities. To target
this platform, Dr. Finlayson’s group developed MS INFoRM (Multiple Sclerosis: An Interactive
Fatigue Management Resource), a self-directed resource that addresses key components of
managing MS fatigue in the context of daily life. Her study will determine whether MS INFoRM
contributes to reducing fatigue. They will also look at whether it improves other important
outcomes like cognition, feelings of self-worth, depression, and participation and
independence. The goal of this study is to improve access to fatigue management in Canada
and beyond.

Elucidating the mechanistic role of latent EBV
infection in the etiology of MS
Epstein-Barr virus (EBV), best known as the cause of infectious mononucleosis (mono), is
believed to play a role in the cause of MS. The risk of developing MS is 10 times greater in
individuals infected with EBV during childhood, and 20 times greater in those who have
developed mononucleosis. In his previous grant funded by the MS Society, Dr. Horwitz
identified that mice infected with an EBV-like virus developed a disease highly reminiscent of
MS. His current project builds on these findings to further examine the mechanism by which
EBV influences the development of MS. The ultimate goal of Dr. Horwitz’s project is to refine
therapeutics to interrupt these specific EBV-immune interactions and prevent MS.

Immigration and the risk of multiple sclerosis

Studying rates of MS amongst immigrants to Canada can help to understand why Canada is one
of the highest risk regions for MS in the world. Immigrants are thought to be at lower risk for
developing MS than people born in Canada, but their risk is still believed to be higher than
that in their native countries. In this study, Dr. Rotstein’s work, which will study the risk of
developing MS amongst immigrants in Ontario, may lead to the creation of the largest and
most diverse cohort of immigrants with MS. Administrative data will be used to understand
how access to health resources for immigrants with MS compares to access for Canadian-born
individuals with MS. These findings will allow health professionals to tailor their care to the
unique needs of the immigrant population with MS, while also providing important insights
into risk factors for MS in general.

Establishing an imaging biomarker for
disease progression in multiple sclerosis

Biomarkers are biological clues from the body that can tell us about the state of a disease or
the effect of a treatment. The most promising brain imaging biomarker in MS is change in
brain volume, however this can take over a year to confirm and is only partially linked to
progression. As a potential alternative, Dr. Kolind’s research team wants to explore the loss
of myelin as a potential biomarker. The integrity of myelin determines the health of neurons,
and myelin loss can reflect the severity of MS disease. Dr. Kolind’s research team plans to use
imaging tools that can detect and measure structural changes in myelin, which in turn can
provide information about disease progression. Dr. Kolind hopes that her findings will help

severe progression; and (3) reduce the cost and time required for progressive MS clinical

MRI of Deep Grey Matter in multiple sclerosis
Magnetic Resonance Imaging – or MRI – is a powerful tool that enables clinicians and
researchers to diagnose and monitor MS, as well as assess the effects of treatments. Research
in this field is advancing quickly, however appropriate imaging measures that accurately track
disease progression remain elusive. Dr. Alan Wilman’s project plans to test new MRI methods
that may enable better tracking of MS by examining the whole brain. The idea is to create
new ways of performing MRI that are specific to particular biological changes that occur in
the brain (not just in lesions) such as examining deep parts of the brain that are linked to
movement and where iron is stored in the brain. This work will advance the understanding of
MS by examining the brain with new MRI methods that reveal different processes that are
currently not tested in the clinic with the hope to enable physicians to make a more effective
assessment of MS disease state and understand the effects of therapy.

Role of M2 macrophage subtypes and iron in Experimental
Autoimmune Encephalomyelitis
Although inflammation is generally regarded to be a harmful process in the MS brain, certain
types of immune cells have been found to have beneficial effects on the disease. Dr. Samuel
David is examining a type of anti-inflammatory immune cell called M2 macrophages which
reside in MS lesions. The goal of Dr. David’s study is to determine if transplanting M2
macrophages into mice with an MS-like disease can improve their symptoms. Since beginning
the project, Dr. David has surprisingly found that transplanting control macrophages called M0
was more effective in reducing paralysis in mice with MS-like disease compared to M2
macrophages. Ongoing work will involve exploring whether increasing the number of
macrophages along with molecules that facilitate communication between immune cells will
reduce disability in animals with MS-like disease.

Immune cell-microbiome interactions and neuroinflammation
The immune system has the ability to "put the brakes" on inflammatory responses when
required. In MS, for reasons that are not understood, this breaking mechanism is impaired.
The proposed research from Dr. Gommerman’s group seeks to broaden understanding of
immune regulation by focusing on a specific immune cell called B cells. Preliminary data
suggests that some B cells have an anti-inflammatory function, and that B cells in general are
influenced by microbes that live in the intestines (gut microbiome). The aims of the proposed
research are to determine how gut microbes influence MS in mice, determine how the
microbiome influences B cell function in mice with MS-like disease, and determine how
microbes in the gut influence the brain and spinal cord. The team has already discovered that
the gut microbes have a role in dictating disease severity in mice with MS-like disease that
have compromised B cell function. Surprisingly, they also discovered that this is particularly
true of male mice. This research will delineate how B cells function in MS to establish better
drugs that target B cells to treat MS.

Impact of MicroRNA-223 on Immune and Glial Cells in Multiple
Sclerosis
Dr. Craig Moore and his team are studying specific molecules called microRNAs, which are
potential new targets for progressive MS treatment. Found in both brain and immune cells,
microRNAs play an important role in controlling inflammation and tissue repair in the
damaged brain. The Moore lab discovered one microRNA molecule in particular-called mir-
223- to be important in promoting repair in MS. To characterize the role of mir-223 in detail,
the Moore lab is growing cells in a dish and treating them with mir-223 to determine the
change in the levels of inflammatory signals. Future work from this lab aims to investigate the
role of mir-223 in animal models of MS. Dr. Moore hopes that this research will identify a
novel target that could be further explored for treating both relapsing and progressive forms
of MS.

Role of PTP Alpha in oligodendrocyte maturation and
myelination/re-myelination
Dr. Catherine Pallen’s laboratory has spent many years studying a small molecule called
protein tyrosine phosphatase alpha (PTPa). Their findings, and that of others, have shed light
on the molecule’s importance to the development of oligodendrocytes (myelin-producing cells
in the central nervous system). Now, the team is set to explore how interactions between
PTPa and other neighbouring molecules can, together, guide oligodendrocytes to grow and
produce myelin in cell culture. They will also seek to understand the possible role PTPa plays
in the regeneration of destroyed myelin. Thus far, Dr. Pallen’s research team has discovered
that PTPa promotes the development of oligodendrocytes, mediates interactions between
neurons and oligodendrocytes, and promotes the myelination of nerve fibers. Ongoing work is
exploring the mechanisms through which PTPa exhibits its effects on neurons and
oligodendrocytes. Together these findings provide a foundation for the development of
therapies that promote myelin repair and reverse or ameliorate the debilitating effects of
demyelination in MS.

Defining the requirements and therapeutic potential of VGF
in CNS remyelination
We know that exercise can alleviate many symptoms associated with MS, and in some cases,
slow disease progression. Precisely why is somewhat of a mystery. Previous research led by
Dr. David Picketts identified one possibility – a small molecule called VGF. Produced during
exercise, VGF supports the growth of myelin-producing cells, making it an excellent target for
treatment. Using various cell culture techniques, Dr. Picketts and his team will explore how
VGF stimulates myelination, test the efficacy of specific drugs to boost VGF production and
myelination, and investigate whether VGF can enhance remyelination in a pre-clinical MS
model. They will also assess whether exercise mimetics – drugs that can mimic or amplify the
effects of exercise – can improve remyelination, thus serving as a possible therapeutic
strategy for when physical exercise becomes too challenging. His team is currently trying to
understand if the removal of VGF is detrimental to the myelination process and if VGF is a
potential target for therapeutics to treat MS.

CNS inflammasomes: defenders and disease
determinants in progressive multiple sclerosis
The human brain is home to structures called inflammasomes. These structures are made-up
of many different proteins that, when bundled together, activate the brain’s immune
response. Preliminary work from Dr. Christopher Power’s laboratory suggests that
inflammasomes may fuel the autoimmune attack in primary progressive MS. To test this
theory, Dr. Power and his team will investigate how inflammasomes affect brain anatomy and
function in primary progressive MS, as well as explore what molecules are responsible for
inflammasome activation in cultured human brain cells. The team will also test how
suppressing inflammasome activation affects mice with an MS-like disorder. The research
team has discovered an important inflammasome called NLRP3, which serves a central role in
the inflammatory response and activates cell death cascades, as well as other molecules that
regulate inflammasomes. Their findings will shed light on the role of the immune system in
primary progressive MS and potentially lay the groundwork for the development of biomarkers
and treatments for MS.

DICAM: a novel molecular effector in neuroinflammation
Normally, the brain is not easily accessible to cells of the immune system, as it is surrounded
by a relatively impenetrable wall of cells called the blood-brain barrier. However, in MS, a
large number of immune cells are able to cross this barrier, leading to the formation of brain
lesions. Dr. Alexandre Prat and his team previously identified a possible tool that is used by
aggressive immune cells to by-pass the barrier: a molecule called DICAM. Using a combination
of experimental techniques, including analysis of cells from people with MS, Dr. Prat’s team
will explore which cells of the immune system express DICAM, and how these cells use DICAM
to cross the blood-brain barrier. The team will also test whether there is any benefit to
manipulating DICAM in mice with an MS-like disorder. The researchers’ overarching goal is the
eventual development of DICAM-targeting drugs that limit lesion formation in MS. Thus far,
the research team has demonstrated increased quantities of DICAM in people with relapsing-
remitting MS, compared to healthy donors. Furthermore, the data reveals that DICAM is
expressed on a type of white blood cells called T helper 17 cells (Th17), which are the leading
agents of inflammation in the central nervous system. Fortunately, Dr. Prat is investigating a
promising molecule called 9E9 which appears to block the migration of Th17 cells
subsequently reduce disability in animal model of MS-like disease.

Role of Astrocytes and Endothelium in BBB regulation and CNS
Immunity
A layer of cells called the blood-brain barrier surrounds and protects the brain. Unfortunately
in MS, aggressive immune cells penetrate the barrier and cause damage and lesion formation.
Molecules made by either the blood-brain barrier itself, or supporting cells in close proximity
to the barrier help determine the barrier’s effectiveness at blocking unwanted immune
incursions. Using advanced cell culture techniques and genetically modified mice, Dr.
Alexander Prat’s laboratory will explore how three molecules produced by the blood-brain
barrier and supporting cells called astrocytes, help form a tight and impermeable blood brain
barrier. Thus far, Dr. Prat’s research team has discovered that therapeutically blocking one of
those proteins (netrin-1) reduces penetration of aggressive immune cells and leads to
decreased disability in animals with an MS-like disease.

The role of the quaking proteins in oligodendrocyte
physiology and myelination
Within the oligodendrocyte, the brain’s myelin-producing cell, a vast array of proteins are
tirelessly at work; first, pushing the oligodendrocyte to generate myelin and then protecting
and sustaining the oligodendrocyte and myelin over a person’s lifetime. Using genetically
modified mice, Dr. Stéphane Richard and his team will study one of these proteins – Quaking 1
(QK1) – to determine how it supports and maintains oligodendrocytes and myelin at the
molecular and cellular levels; both during early development and then later in adult life.
They will also test whether QKI is necessary for remyelination, the ability of oligodendrocytes
to generate new myelin following injury to the brain and spinal cord. The research team has
already created genetically modified mice that lack the QK1 protein, and discovered that
these mice display characteristics suggesting that the protein may be important for
myelination and could be an important area to further study in the context of MS.

Targeting Oligodendrocyte Maturation for the Study of Axonal
Survival

Myelin loss often leads to damage to nerve fibers, rendering them unable to communicate
with one another and causing them to die (degenerate). This loss of nerve fibers is thought to
underlie the progressive stage of MS. Previous research has identified a key molecule involved
in this process of remyelination during development is MYRF. Using genetically engineered
mice lacking MYRF, Dr. Tetzlaff’s research team has discovered that MYRF is required to
promoate remyelination. Furthermore, the team has removed MYRF from remylinating cells to
show inhibition of the remyelinaton process. The Tetzlaff research team now hopes to use
this established model system that prevents remyelination with the removal of MYRF to test
which drugs will preserve the demyelination of neurons.

Novel strategies to enhance intrinsic repair following
demyelination
By briefly reducing the amount of oxygen available for breathing and/or using short bursts of
electrical stimulation, Dr. Valerie Verge’s laboratory has managed to improve the nervous
system’s self-repair mechanism in rats. In her latest project, Dr. Verge’s research team will
test whether these two techniques can boost the spinal cord’s ability to repair nerve and
myelin damage in mice. Similar experiments to improve regeneration will be carried out in
mice with an MS-like disease. To date, the research team has completed studies showing that
brief electrical stimulation of demyelinating neurons changes the role of harmful immune
cells called macrophages from a pro-inflammatory response to a pro-repair response. Dr.
Verge is hopeful that the stimulating treatments will enhance remyelination, while also
protecting vulnerable and damaged axons – a goal of great importance for those living with
MS.

Targeting novel functions of cysteine cathepsins to limit
neuroinflammation
Inflammation in MS is caused by cells of the immune system travelling to the brain and
releasing molecules called cytokines. These cytokines are used by immune cells as a way to
communicate with each other, and in MS they can prompt immune cells to cause damage to
the central nervous system. One important cytokine in MS is IL-1. The Yates research group
has evidence to suggest that a protein called cathepsin stimulates the release of IL-1 and that
mice that don’t have this protein show lower levels of brain inflammation and a milder MS-
like disease course. Dr. Yates’ research will break down role and mechanism of action of
cathepsins in MS. In the past year, the research team has identified the involvement of a
particular cathepsin in triggering IL-1 activation. This discovery will pave the way for further

Mechanisms and parameters of exercise-induced
remyelination in mice
Loss of myelin, the protective covering of nerve fibers, is a hallmark of MS. The Yong lab has
been researching various means to promote remyelination using mice with experimentally-
induced injury to the spinal cord. Given that physical activity is known to improve wellness in
people with MS, Dr. Wee Yong and his team are exploring whether physical exercise can
promote remyelination. They have generated exciting data demonstrating that mice who are
given free access to a running wheel following injury in the spinal cord form new
oligodendrocytes and myelin over two weeks compared to mice with injury that do not
participate in physical activity. The current grant proposal seeks to understand how physical
exercise promotes myelin repair, and determine the type, duration and intensity of physical
exercise that is needed for successful repair following neurological damage.

A community-based randomized controlled trial testing
implementation of the new Canadian Physical Activity
Guidelines for Adults with Multiple Sclerosis
Physical activity has gained a great deal of attention recently for its potential to help people
with MS manage their symptoms. Recently, new physical activity guidelines (PAGs) for people
with MS were released. The next step is to determine how best to implement these guidelines
in the broader community. Dr. Audrey Hicks is leading a controlled clinical trial with 3 aims:
to compare how individuals with MS follow the PAGs; to ensure that following the PAGs will
result in improved fitness, function and perceived quality of life; and to explore whether
following the PAGs will impact key risk factors for other conditions such as heart disease,
diabetes and stroke. Dr. Hicks has completed testing on 69 participants to date, and
discovered that participants that adhered to PAGs 75% of the time (during the 16 week study
period) experienced significantly improved strength, reduced fatigue, and improved mental
and physical health-related quality of life.

A Randomized, Controlled, Clinical Trial of Continuous
Positive Airway Pressure Treatment of Obstructive Sleep
Apnea-Hypopnea in Multiple Sclerosis
Obstructive sleep apnea-hypopnea (OSAH) is the most common sleep abnormality in people
with multiple sclerosis (MS), and is associated with increased fatigue and pain. Dr. Trojan’s
preliminary research showed that treatment of sleep disorders (mostly OSAH) can markedly
improve fatigue and other symptoms in some MS patients. The goal of this project is to test
the effect of OSAH treatment in a scientifically rigorous study to confirm improvements in
sleep quality, fatigue and other symptoms that dictate the quality of life in MS. The best
treatment for OSAH in the general population is continuous positive airway pressure (CPAP).
Thus far, Dr. Trojan has confirmed the observation of OSAH in individuals with MS and tested
the feasibility of the research to support long-term CPAP treatment. Over 40 individuals with
MS have been recruited to participate in the study with nearly 25 that have already
completed the trial.

The pain connectome in Multiple Sclerosis
Over half of all people living with MS experience chronic pain. Why some individuals
experience pain and others do not remain a mystery. A possible answer lies in the strength
and dynamics of the brain’s pain network – a series of interconnected brain areas that
collectively dictates a person’s pain experience. Using advanced magnetic resonance imaging
(MRI) techniques, Dr. Karen Davis and her team will explore the relationship between the
health and activity of connections within this network and MS-related pain. The research will
provide much needed insight into why and how the brain misinterprets or creates pain signals
in MS. This holds the promise of creating individualized, targeted therapeutics to modify or
alter a maladjusted pain network. Thus far, the research team has recruited and tested 40
healthy participants on behavioural tests and acquired brain imaging data. Furthermore, Dr.
Davis has established a collaboration with the MS Clinic at the St. Michael’s Hospital and have
initiated recruitment of patients at that site as well.

Sex and Central Nervous System Autoimmunity
MS affects three times more women than men. The reasons for this sex difference in MS
incidence are still unknown. Some studies have provided evidence showing that the immune
response is more vigorous in women than men, which would explain why an autoimmune
attack on myelin is more likely to happen in women. Dr. Dunn’s research team plans to
explore this idea further. Her lab has already revealed that an inflammatory factor called IFN-
γ is released in female, but not male rodents. The team will attempt to expand on this
finding to people with MS and determine if women have more active immune systems that
attack myelin than those in males.

Coming off cannabis in MS: a longitudinal, cognitive
and fMRI study

Between 40% and 60% of people living with MS experience difficulties with their cognitive
functioning. Cognitive impairment is associated with greater difficulty in securing a job,
functioning socially and pursuing leisure activities. Almost one in five people with MS report
using cannabis (marijuana) for symptom relief, most notably for pain and spasticity. However,
new evidence indicates that smoking cannabis may worsen cognitive function in MS. What is
not known, however, is whether these cognitive changes are reversible if a person with MS
stops smoking cannabis. Dr. Feinstein and his team will pursue this question by performing
cognitive testing and brain imaging on two groups of participants: one group will be
instructed to stop using cannabis while the other will be allowed to continue, and both groups
will be followed for 28 days. Preliminary data suggests that individuals with MS who abstain
from cannabis use show less cognitive impairment. Overall, the results of this project will be
important in educating people living with MS and physicians alike about the effects of
cannabis on cognition.
