4Improved Understanding of Healthier Diets
Grant Project Title Drivers of Eating Behaviour: chronic overconsumption
Reference: homeostatic, hedonic, and biological markers
BB/G005524/1
Investigator(s) Prof John Blundell and Dr Graham Finlayson
Research Professor John Blundell (JB) has over 20 years experience of managing large scale
Expertise research projects in the area of psychobiology of appetite control, energy balance,
physical activity, nutrition and drugs as a Principle Investigator (PI). During a series
of large scale projects funded by research councils, industry and EU, a high quality
research infrastructure has been developed with an advanced methodological
platform for the study of food, appetite, nutrition, exercise and energy balance. An
interdisciplinary science base has been built up within a research culture of
documented Good Laboratory Practice adn internationally recognized research.

Dr Graham Finlayson is a biological psychologist. His research is concerned with
the interaction of hedonic and homeostatic systems that underpin human eating
behaviour.
http://www.psyc.leeds.ac.uk/cgi-bin/10/people/index.pl?grahamf
Project This project was designed to uncover the way in which people eat, and their
Overview susceptibility to overconsume during an extended and realistic challenge to energy
balance. Because eating is part of a ‘complex’ system, we established a multi-level
experimental platform based on a biopsychological systems approach. The platform
was designed to monitor adaptive pressure on internal and external processes that
drive appetite. Research studied obese participants undergoing long term physical
activity and dietary challenges to uncover individual variability in positive energy
balance – a ‘safe model of overconsumption’. Research monitored effects on
homeostatic (hunger, meal size, EI) and hedonic (liking, wanting, food choice)
markers of appetite in relation to changes in body composition, RMR and
psychological traits. The project has also enabled the development of an innovative
and comprehensive assay system to simultaneously monitor changes across all
major plasma hormone biomarkers and metabolites.
Industrial First demonstration that body composition and resting metabolism (RMR) are
Impact fundamental drivers of homeostatic aspects of appetite (satiation and satiety) and in
the presence of high energy dense foods, lead to overconsumption. A realistic
criterion for overconsumption reflected in an objectively measured EI:RMR ratio
establishes a benchmark for study of eating behaviour to identify associated
homeostatic and hedonic mechanisms; and to cleanly test the effects of nutritional
components on satiety. Action of ghrelin (‘hunger hormone’) understood through a
distinctive 3 phase action on satiety (early and late stages) and satiation (control of
meal size).Study outputs have implications for measuring the satiety impact of novel
foods, and show that the process of satiety is complex and incorporates changes in
the amount of food eaten, food choices, liking and wanting, and the temporal profile
of GI hormones such as ghrelin.
5Grant Project Title Understanding decisions about portion size: The key to acceptable
Reference: foods that reduce energy intake?
BB/G005443/1
Investigator(s) Dr Jeff Brunstrom, Prof Peter Rogers
Research Dr Jeff Brunstrom and Professor Peter Rogers co-lead the Nutrition and Behaviour
Expertise Unit, based in the School of Experimental Psychology at the University of Bristol.
The unit is housed in a newly refurbished laboratory with extensive food-preparation
facilities and the equipment and technical expertise to assess psychological and
physiological responses to food. Currently, the Nutrition and Behaviour Unit
accommodates the activities of four post-docs, four research assistants, and six
Ph.D. students. Postgraduate students receive funding from a number of sources,
including an ESRC competitive studentship, a BBSRC-DRINC award, a King
Abdullah scholarship, a BBSRC-GSK industry-CASE award, a Cadbury-Great
Western Research grant, and a BBSRC quota award. This ‘critical mass’ of
researchers creates a highly stimulating and lively research environment. Our group
meets on a weekly basis and interacts with other staff and students working in
cognate research areas, such as addiction (primarily smoking and alcohol),
psychopharmacology and genetics.The unit has considerable experience working
with the food industry. Recent projects have focused on psychobiological controls of
food intake and portion size, the psychopharmacology of caffeine, and effects of
food on cognition and mood. In 2012 Brunstrom and Rogers will begin a 3-year
BBSRC-LINK funded project exploring effects of eating behaviour on satiety. This
work is co-funded by Nestlé.
http://food.psy.bris.ac.uk/index.htm
Project Researchers with an interest in energy intake tend to focus on 'amount eaten' or
Overview self-reported hunger and fullness after a test food has been consumed. The logic
here is that meal size is normally determined by psychological and physiological
‘events’ during and towards the end of a meal. This project aims to 1) challenge this
fundamental assumption and 2) show how an understanding of portion-size
decisions can help us to identify palatable foods that promote lower energy intake.
Industrial Our research addresses the hypothesis that portion-size decisions are an important
Impact determinant of energy intake. If this is the case (as we suspect), then it follows that
by understanding how decisions are made we can design products that are both
acceptable and which are expected to deliver maximum satiety. Products of this kind
will promote reduced energy intake, because they will be selected and consequently
consumed in smaller portions (in kcals). For the food industry, research of this kind
could prove invaluable, especially in the development of effective 'diet' (e.g. low
calorie) products. In particular, we anticipate two specific benefits the project will
provide: 1. insight into specific foods and food characteristics that have high
expected-satiation/satiety. 2. a methodology that can be used in-house to quantify
expectations and beliefs about new and existing food products. These methods will
be rigorously tested and will draw on cutting-edge techniques in psychometric
assessment.
6Grant Project Title Defining the gut-to-brain signalling mechanisms underlying
Reference: responses to nutrients
BB/G005591/1
Investigator(s) Prof John McLaughlin
Research The Gastrointestinal Sciences Research Group is a multidisciplinary group of
Expertise individuals bringing together clinical investigators, biological scientists and
population researchers who are interested in the various aspects of science of the
gastrointestinal tract.
Our research encompasses a spectrum between basic molecular studies in
epithelial biology and neuroscience, and clinical research including
enteroendocrinology (the physiology of gut signalling peptides),
neurogastroenterology (the control of gastrointestinal function via the enteric and
central nervous systems) through to population based epidemiological studies and
clinical trials. The team provide seamless transition from bench-to-bedside. Close
collaboration with imaging science colleagues (Dr Shane McKie and Prof Steve
Williams) are pivotal to current work, utilising physiological MRI scanning to study
the effects of nutrient induced gut-to-brain signalling on human brain function. The
regulation of appetite in health and disease is a key current focus. Currently the
group are also working on establishing primary models of enteroendocrine cells for
physiological study of nutrient sensing mechanisms, and exploring the interactions
between the enteroendocrine cells and the immune system in gastrointestinal
inflammation.
http://www.medicine.manchester.ac.uk/gastrointestinal/research/
Project The key aim of the project is to understand the biological mechanisms by which
Overview sugars and sweet tastants are sensed by the gastrointestinal tract and influence
food intake, in particular via the enteroendocrine system. This is closely coupled to
mapping the spatiotemporal matrix of activation in the human brainstem and other
CNS areas by these nutrients, based on cutting edge imaging and analytical
techniques developed in Manchester. This is permitting exploration of the
gastrointestinal regulatory peptides secreted in response to nutrients in the
regulation of gut-brain signalling, gastric emptying, and appetite.
Industrial The health and prosperity of the population are under serious threat as a
Impact consequence of overeating, and the resulting increase in the incidence of
overweight and obesity. Understanding the mechanisms by which nutrients signal
from the gut to the brain, and in particular how this influences appetite and food
intake, are critical first steps to the development of novel satiating foods and
beverages, and will also inform the complementary biomedical fields.

Project 1. To use a unique delivery system to increase colonic propionate production.
Overview 2. To determine the effect of supplementing the diet of obese volunteers with the
propionate carrier molecule change on appetite and body weight.
3. To investigate the effect of the propionate carrier molecule on the release of the
anorexigenic gut hormones GLP-1 and PYY.
4. To investigate if increases in plasma propionate concentrations leads to a
decrease in free fatty acid output from adipose tissue leading to improved
insulin sensitivity.
5. To design foods which can be used to supplement the diet of the general
population with the propionate carrier molecule.
Industrial This work could provide a major benefit to the food industry. Few non-digestible
Impact carbohydrates have been shown to have a significant or specific impact on
propionate production. In this proposal research includes use of a propionate carrier
molecule to deliver high levels of propionate to the large bowel. Should this work
demonstrate the efficacy of propionate on appetite regulation, body composition and
insulin sensitivity this could lead to the development of foods designed to increase
propionate in the large bowel in ways acceptable to the consumer.
8Grant Project Title Maximising satiety through manipulating expectations, sensory
Reference: quality and nutrient content
BB/H004645/1
Investigator(s) Prof Martin Yeomans
Research The Ingestive Behaviour Unit in the School of Psychology at University of Sussex is
Expertise a state-of-the art research facility for studying psychological influences on human
ingestive behaviour, including facilities for preparation of novel test food and drinks,
for analysing the microstructure of human ingestive behaviour using Sussex
Ingestion Pattern Monitor (SIPM) technology (www.sipm.co.uk) and to allow testing
of cognitive and affective changes relating to ingestion. These behavioural
measures can be combined with more physiological assessments, including assay
of appetite-related hormones, with additional facilities at Sussex for neuroimaging to
allow evaluation of the neural basis of responses to food stimuli. Lead by Professor
Yeomans, the Sussex Team currently comprises a full-time RF and 4 full-time DPhil
students. Also associated with this project are facilities in the University of Brighton
School of Service Management (Mr Harvey Ells, collaborator at University of
Brighton). The Culinary Arts Studio is a research restaurant environment used both
as a training space for the catering industry and a unique research space for
studying human behaviour in a naturalistic environment.

Project The objectives detailed in the original proposal:
Overview
1. Explore how expectations generated by labelling and sensory quality interact
with protein content to generate satiety
2. Examine how labelling and sensory quality impact on physiological satiety
responses
3. Test the effectiveness of prototypical high-satiety formulations on consumer
behaviour in controlled intervention studies
Industrial There is increasing demand from consumers for food and drink products that are
Impact both enjoyable to consume but which also help prevent over-consumption. Thus
optimal new products should be engineered to maximise satiety as well as flavour
acceptability. As the experience of liking and satiety is influenced by product beliefs
and sensory quality as well as nutrient content, industry needs design rules that
allow them to integrate these different factors in an effective way to facilitate novel
product development. The aims of this project are to provide evidence-based
examples of how to integrate these components effectively.
9Grant Project Title Reducing saturated fatty acids in the food chain through alteration
Reference: of milk fat composition
BB/1006087/1
Investigator(s) Prof Ian Givens
Research The research team involved in this study is a combination of staff mainly from two
Expertise departments at the University of Reading, namely the Division of Food Production
and Quality and the Deptartment of Food and Nutritional Sciences. The team has
nutrition-focused expertise across the food chain which includes a large food-
producing animal research unit at one end and a state of the art human nutrition
research unit at the other. Both departments have extensive laboratory facilities. The
animal research unit is equipped with large animal calorimeters and thus the
environmental aspects (e.g. methane output) of using animals as food producers
can be measured. Animals’ diets can be tuned to produce, for example, milk with
altered lipid profile and this can be used to make dairy products (cheese, butter,
etc.) which can be used in human intervention studies to examine the effects on
markers of chronic disease. In relation to the current project, the team has particular
expertise on dietary lipids and vascular health with emphasis on the role fatty acids
in bovine milk which exist as a highly complex mixture and include some unique
trans and branched chain fatty acids.
http://www.reading.ac.uk/apd/about/apd-stafffpq.aspx
http://www.reading.ac.uk/food/
Project Overall objective: to reduce saturated fatty acids (SFA) entering the UK food chain
Overview by targeting milk, with concomitant reduction in the environmental impact of milk
production. Sub-objectives:
To confirm that the milk fatty acid response to dietary change in large,
commercial dairy herds with differing dietary backgrounds is consistent and of
adequate magnitude.
To explore the impact of dietary oilseeds and new rumen protection technology
of fats on their ability to replace SFA by cis-MUFA/cis-PUFA without substantial
accumulation of trans-MUFA, in association with an understanding of the dose-
response of dietary oilseeds on methane production per litre of milk produced.
To ensure that the project findings are successfully integrated and
disseminated to various levels (industry, policy makers, health professionals,
general public etc).
Industrial Until this project, it was not known whether strategies to reduce saturated fatty acids
Impact (SFA) in milk by changing the cow diet would provide sufficient changes when
applied to commercial herds, as previous research has only been conducted in
experimental situations. In addition, there may be means to sustainably reduce SFA
to a greater extent than previously thought. This project is of huge benefit not only to
members of the dairy food supply chain (from farm production through processor,
retailer and the consumer) but also the food industry in general given that dairy
products are present in a vast array of different foods.
10Bioactives in Foods
Grant Project Title Self-structuring foods with slow burn for control of satiety
Reference:
BB/G005478/1 Investigator(s) Prof Ian T Norton
Research The Microstructure Group at the University of Birmingham led by Professor Norton
Expertise carries out research into novel applications of foams, emulsions and gels for the
formulation of healthy foods to combat obesity. The Group runs research projects
that aim to reduce the energy density of foods, maintain sensory acceptability and
hedonic rating, and increase their satiety.
The Microstructure Laboratory (MSL) develops inventive techniques for designing
interfacial and surface properties of food gels and emulsions, the latter with feature
sizes ranging from nano/micrometers, and uses these structures in a range of
research projects. The MSL includes facilities for processing (microfluidizer,
impinging jet, homogenisers, membrane emulsification, and pin stirrer heat
exchangers), thermoanalysis, polarimetry, spectroscopy, microscopy (light, confocal
and electron microscopy), assessment of material properties (rheological, fracture,
lubrication and interfacial) and a food sensory assessment laboratory. Much of the
emulsification equipment, and methods, utilized in the MSL are developed in-house.
The research projects within the MSL fall into three closely interlinked major
categories: process development (emulsification, gelation and encapsulation),
formulation process design (colloidal particles at interfaces, material properties) and
in-use properties (oral properties and cooking behaviour).
http://www.birmingham.ac.uk/research/activity/chemical-engineering/index.aspx
Project The overall aim of our project has been to formulate a variety of novel liquid, soft
Overview solid and semi-soft solid (paste-like) foods that are enjoyable to eat and that are also
capable of responding to the body's natural processes of digestion in the stomach
by self-structuring and slowly releasing nutrients. Such foods would have a major
impact on the obesity problem because they would potentially control satiety.
Industrial Based on the project findings the research team propose that it is possible to
Impact successfully gel (structure) acid-sensitive solutions at pH values found in the
stomach and to break (de-structure) the resulting gels within a desired time frame by
forces typically found in the stomach. It is also feasible to improve the performance
of these gels by adding other components. These can include other hydrocolloids,
ingredients that release energy (i.e. oil, starch and proteins), nutrients, colours and
flavours. Ingredients could be encapsulated in hydrocolloid shells for controlled
release at various stages within the gastrointestinal tract. Instead of simple oil-in-
water emulsions, double emulsions could be trapped within the gel network. There
are endless possibilities for inclusion of more complex structures.

3. Determine the rate and extent of lipid and starch digestion of plant foods in vitro
& in vivo.
4. Develop mathematical/kinetic models for predicting bioaccessibility of lipid and
starch.
5. Identify the mechanisms by which PCW influence nutrient release and digestion
kinetics.
Industrial Modelling starch digestion kinetics has highlighted for the first time three structure-
Impact related stages of amylase hydrolysis (fast, medium and ‘resistant’), and has
implications for controlling Glycaemic index, satiety, distal nutrient delivery and large
bowel health.
Modelling lipid bioaccessibility has implications for developing dietary and recipe-
based approaches for modulating nutrient delivery with potential beneficial impacts
on weight management, satiety and plasma lipid profile.
Both models could inform strategies for the rational processing of plant-based
ingredients to optimise health benefits.

Project Bread is a staple food in the UK diet with a high glycaemic index (GI). Any reduction
Overview in GI is likely to make a significant contribution to promoting the health on the nation,
low GI foods being protective against conditions such as type 2 diabetes. However,
we currently lack the understanding and tools to modify the GI of bread in a
knowledge-based way. This project unites plant scientists, food scientists and
engineers to build fundamental understanding of how natural variation in the
composition and solubility of the fibre fraction (specifically arabinoxylan (AX)) of
wheat endosperm cell walls is modulated by processing and digestion.
Industrial The aim of the project is to study how breads with different fibre contents are
Impact digested and identify how the effects of changing the composition and solubility of
the fibre fraction might affect digestion and thus GI. The work could lead to better
understanding of the digestion of fibre and aid in the formulation of breads with
health benefits.

Project The D2-D3 study (a food fortification intervention trial) has primarily been set-up to
Overview compare the efficacy of 15µg/d [600IU/d] vitamin D2 vs. 15µg/d vitamin D3 in raising
serum 25(OH)D levels in both caucasian and south asian women above the
‘deficiency/insufficiency’ thresholds (25nmol/l and 40nmol/l respectively) during the
winter months. The mechanism behind any vitamin D effects will be investigated via
enzymatic and genetic analysis.
Industrial Information on the comparative effectiveness of the two different forms of vitamin D
Impact as food fortificants in raising 25OHD levels in UK populations with known
‘insufficiency’ (caucasian) and ‘deficiency’ (south asian) will prove invaluable to the
food manufacturing industry.
This study also presents an excellent opportunity to elucidate whether the food
vehicles used in the study (a juice and a biscuit) are appropriate in terms of both
acceptability to the study population and the stability of the vitamin D in the
respective food vehicles.

http://www.leatherheadfood.com/sensory-and-consumer
Project The overall aim of the project is to determine the fundamental colloidal mechanisms
Overview by which the interfacial layer of emulsion droplets can be manipulated to control the
structure and rheology of emulsified foods in order to improve the organoleptic
properties and consumer preference of reduced fat foods.
Industrial The outputs of the project will be a set of design rules which food manufacturers can
Impact use to create emulsified foods with improved sensory quality in terms of perception
of fat content.
The aim is that these strategies can be applied to reduced fat foods which have poor
perceived quality, and thus increase their uptake by consumers.
This approach should also reduce the need for adding other ingredients such as
starch, salt and sugar, which are often added to improve the sensory quality of low
fat foods, but reduces nutritional impact, this approach will therefore result in real
improvements in the nutritional quality of the foods, and savings in raw materials
costs.

Project Numerous studies have indicated that the consumption of flavonoids is associated
Overview with a lower incidence of cardiovascular disease (CVD) and associated mortality.
This project has selected the most commonly consumed flavonoid species in the UK
diet, their immediate degradation products, and metabolic by-products in order to
assess their cardioprotective activities. Compound efficacy as cardioprotective
phytochemicals will be assessed in isolation and in combinational treatments,
designed to mimic typical dietary consumption. The effectiveness of dietary
flavonoids to reduce the detrimental effects associated with the onset of CVD
conditions will be assessed by monitoring their activity on inflammatory cytokine
expression, vascular reactivity, and the regulation of transcription factors related to
the development of CVD. Data generated from this study will make it possible to
infer the structural characteristics associated with the beneficial health effects of
flavonoids. It will also provide insight to whether these flavonoids work in isolation,
or if, as in typical consumption (in combination), exert their beneficial effects in a
collective manner.
Industrial Flavonoids are present in a plethora of foodstuffs consumed everyday in the UK The
Impact identification of specific flavonoids, and combinations of flavonoids, within these
foodstuffs that act as cardioprotective phytochemicals will help identify targets
(compounds, doses, and clinical endpoints) for future intervention studies required
to establish health claims.

Project There is convincing evidence that the obesity epidemic is becoming worse, with
Overview the World Health Organisation indicating that the number of people who will be
overweight and obese by 2015 will be 2.3billion and 700million respctively. An
alternative treatment to reduce obesity may be fibre. Since the early observations
of Hipsley (1953) vast amounts of research have been conducted on the
physiological benefits that fibre may have, such as:
Gut health where fibres add bulk to faeces and aid passage through the
digestive system preventing constpation
Increased level of satiety and transit time and slowing gastric emptying
Reducing the breakdown of carbohydrates thus slowing down absorption

Project There is little information on the effect of oral catechin, a nutritionally relevant
Overview bioactive compound, on skin health in humans in vivo, despite considerable
evidence for protective effects, including against UV stresses, in experimental
studies. Vitamin C is essential for skin health, and also stabilises catechins in the
gut lumen. Ultraviolet radiation in sunlight is a key environmental stressor
impacting on skin health, effects including acute inflammation and longer-term
photodamage. Research will examine protection by a combination of dietary
catechin and vitamin C on UV-induced inflammation, through a randomised
controlled double-blind study. Specifically, research will examine for skin erythema,
leucocytic infiltration, and for molecular mediators of these processes in samples of
skin and skin fluid. Research will determine bioavailability of catechin and levels of
UV protection. Further, skin samples taken will also be used to assess for
immunohistochemical evidence of protection against UV-induced DNA damage
and changes in MMP-1, fibrillin-1 and pro-collagen-1, in a short–term model of
photoageing. Overall, this project will establish efficacy of bioactives against UV-
inflammation, the oral and skin nutrient levels required, and indicate potential
against longer-term skin damage.
Industrial Catechins are a group of dietary bioactive compounds found as components of
Impact green tea and other beverages advertised for their ‘protective’ properties. Thus, our
study will offer scientific justification and advice for the correct utilisation/
administration/dosage of catechins in promotion of skin health and protection from
short and longer-term damaging effects of sunlight. Data gained from our study
objectives will aid industry to formulate preparations and/or fortify foods and assist
their claims for beneficial properties.

http://www.st-andrews.ac.uk/chemistry/
Project Available data suggests that consumption of anthocyanins (ACN) such as cyanidin-
Overview 3-glucoside (C3G) may be protective against cardiovascular disease (CVD).
However, ACN bioavailability is perceived to be low and given that they are prone to
degradation during commercial processing, storage and following ingestion, their
degradation products and metabolites are likely to contribute to their bioactivity. This
hypothesis is being explored using a combination of synthetic chemistry, studies of
fruit processing and storage, a stable isotope metabolism study in humans and the
evaluation of metabolite bioactivity using cell culture models.
Industrial As berry juices are the most commonly available vehicle for the delivery of
Impact anthocyanins to the consumer, it will be determined if processing leads to
degradation of anthocyanins or other structural changes that may affect their
bioactivity. There is also little known about what happens to anthocyanins once they
are consumed and what bioactive forms of the parent compound contribute to
prevention of CVD. The findings of this study will provide evidence to form the basis
of future studies that are necessary to establish health claims for anthocyanins.

Project The project aims to:-
Overview
i) Identify trends in the redox status of thiol pools in plasma and PBMCs in a UK
cohort stratified by age from 20-99 years, and correlate this with inflammatory
cytokine expression and nuclear factor-κB (NF-κB) activation.
ii) Identify polyphenols capable of modulating thiol redox and cytokine
expression in vitro.
Provide polyphenol-enriched foodstuffs to volunteers aged 80 years and over to
identify polyphenols capable of reversing changes in thiol redox and cytokine
release observed with ageing.
Industrial The project will identify and validate polyphenols as dietary supplements to reduce
Impact markers of inflammation in ageing. Reduced inflammation is correlated with better
general health and reduced disease risk.
Polyphenols which research identifies as anti-inflammatory could be used as
supplements for dietary products e.g. yoghurts, drinks etc., with validated health

Project Ageing results in a decline in immune function, resulting in greater susceptibility to
Overview infection, particularly respiratory infection, and a poor response to vaccination.
Evidence suggests that pre- and probiotics may enhance immune function and act
as adjuvants to vaccination. The aim of this study was to investigate the effects of a
novel probiotic and prebiotic mixture (synbiotic) consisting of 5x108 CFU of
Bifidobacterium longum bv. infantis CCUG 52486 and 8g of glucooligosaccharide
(GIOS), on the immune response to influenza vaccination in young and older
subjects. Statistical analysis will evaluate prognostic factors determining the efficacy
of the response to vaccination, and whether the response to the synbiotic is
influenced by an ageing immune system.
Industrial Marketing of products containing pre- and probiotics is based on benefits for gut
Impact health and immune defences. EFSA have indicated that robust data showing
improvement of the efficacy of vaccination may be permissible as evidence for
claims relating to immune function. This research has successfully completed such
a study using a novel, non-commercialised symbiotic developing methodology that
could be applied to test the adjuvant properties of any product with respect to
vaccination. Importantly, we are using cells cryopreserved during the intervention to
conduct detailed immunological analysis to understand the mechanisms underlying
the influence of pre- and probiotics on immune function in the context of ageing.

Research Caroline was appointed to a lectureship position at the RVC in late 1997 and
Expertise now holds a Chair in Vascular Cell Biology. She is currently co-ordinator of the
lifestyle research programme with major research interest in endothelial cell
signalling. Her research group is investigating the molecular mechanisms
important for regulating pro- and anti-inflammatory gene expression and
downstream cellular functions in response to a range of external stimuli,
including ligands for G protein-coupled receptors and growth factor receptors,
and exogenous lipoproteins. The group uses in vitro, ex vivo and in vivo cell and
molecular approaches to delineate the signalling pathways controlling gene
expression and functional responses of human and murine large vessel and
microvascular endothelial cells. http://www.rvc.ac.uk/Staff/cwheeler.cfm
Project Chylomicron remnants (CR) are small lipoproteins present in the blood 3-9 hours
Overview after a meal in healthy individuals. Whilst CRs are rapidly cleared from the blood by
the liver in healthy individuals, CR circulation time is prolonged in individuals with
diabetes, renal failure and familial hyperlipemia and there is mounting evidence
linking CRs to endothelial dysfunction and atherosclerosis. Although a number of
beneficial health effects have been proposed for omega-3 polyunsaturated fatty
acids (ω -3 PUFAs) in vivo evidence for efficacy and knowledge of the underlying
mechanism(s) of action are currently lacking.
The aim of this project is to test the overarching hypothesis that, in the postprandial
phase, ω -3 PUFA carried in CR modulate molecular events in endothelial cells
(ECs) and monocytes to reduce arterial wall dysfunction and thus retard
atherosclerosis development. The specific questions to be addressed are do ω -3
PUFA carried in CMR:
1. inhibit pro-inflammatory and pro-oxidant signalling pathways, altering the
balance of inflammatory mediator release, and/or inducing protective signalling
pathways?
2. inhibit reactive oxygen species (ROS) production and pro-inflammatory
signalling) and by limiting their adherence to ECs?
3. Alter the global molecular phenotypes of human ECs and monocytes to favour
vascular protection?
Industrial Characterisation of the pathways and functions targeted by ω -3 PUFA carried in
Impact CRs will lead to a better understanding of the fundamental biological pathways
responsible for CR-mediated actions on the vascular wall, and may also reveal
novel beneficial actions of these fatty acids. Knowledge of these cellular events is
absolutely critical for refining the use of existing food supplements as well as for
informing the development of new supplements, and thus will impact directly on the
ability of the food industry to produce and market foods with substantiated health
benefits.
