Summary
Muscle injury in the elderly often takes longer to heal than in younger people, however the cells responsible for this delayed healing are not well understood. Key inflammatory cells required for muscle repair in young hosts are macrophages. However, during aging we have shown that macrophage function is altered, but the mechanism is unknown. This project aims to determine the mechanisms behind age-related changes to macrophages and whether they can be targeted to improve elderly muscle repair.

Summary
Oestrogen has a number of actions that extend well beyond the regulation of the reproductive cycle and sexual behaviour. The results of recent studies indicate that oestrogen may influence mood and a number of intellectual abilities such as memory and language. In addition, oestrogen replacement therapy seems to reduce the risk of Alzheimer's disease (the most frequent cause of dementia in Western societies) amongst postmenopausal women. The present study aims to: (1) investigate the association ....Oestrogen has a number of actions that extend well beyond the regulation of the reproductive cycle and sexual behaviour. The results of recent studies indicate that oestrogen may influence mood and a number of intellectual abilities such as memory and language. In addition, oestrogen replacement therapy seems to reduce the risk of Alzheimer's disease (the most frequent cause of dementia in Western societies) amongst postmenopausal women. The present study aims to: (1) investigate the association of depression and memory performance with physiological levels of oestrogen in women aged 70 years or over; and (2) investigate the evolution of depression and memory scores in old women treated with oestrogen replacement therapy as compared to placebo. The results of the present study may have important implications in the prevention and management of two of the most relevant mental health disorders of later life: depression and Alzheimer's disease.Read moreRead less
VITAL: Vaccine Immunomodulation Throughout The Aging Lifespan

Summary
The elderly respond less well to vaccines than their younger counterparts. Flu is particularly dangerous to the elderly. In this proposal we will determine the likely immune mechanism undelying this difference, as well as specifically address the urgent issue of whether prior injection with a whooping cough vaccine makes Flu vaccines less likely to be effective.
