Our research is revealing new roles of insulin which may benefit people with diabetes and cardiovascular disease

 

Insulin is widely recognised for its role in reducing blood glucose levels, however it has recently been shown by our research group and others, that insulin plays a role in inflammation. This dual function may have evolved to protect us from contaminated foods which until recently in human history, we would have been frequently exposed to.

The mechanism of how insulin affects blood glucose has been well studied, but how insulin regulates inflammation is less understood because it is such a recent finding.

 

It is important to find out how insulin effects inflammation because insulin levels are significantly higher in the years preceding diabetes diagnosis compared to healthy people; this may contribute to the increased risk of inflammatory diseases such as cardiovascular disease, that people with diabetes suffer from.

Dr Matthew Gage delivers biochemistry lectures in cell signallling, metabolism, endocrinology and ageing and further lecures on animal models of diabetes.

Matthew is a tutor to Gateway and BVetMed students.

Public/ patient talks

Matthew regularly presents his research to the public and enjoys talking about 'working in life science', including presenting to comprehensive schools, Women's Institute talks and BHF and Diabetes UK fundraising volunteer groups.

 

Work experience

Dr Gage's lab also hosts a limited number of school students each summer for work experience in an academic laboratory.

 

School student summary of Dr. Gage's research:

 "The aim of Dr Gage's  research is to expand our understanding of what insulin does and how it does it; to help people with diabetes. Insulin affects inflammation - it seems to be able to both promote and reduce inflammation. In a healthy person, insulin levels increase for a short while after we have eaten, before returning to a low level. In the years preceding type 2 diabetes, insulin levels in the blood are higher than normal and increase much more dramatically after we have eaten. If we can determine how a healthy amount of insulin affects the immune system in a good way, we can use insulin more effectively to manage inflammation in diabetes".
