Summary
Diabetes is the leading cause of blindness in the working population. In some patients with diabetes, blood vessels within the retina proliferate, haemorrhage or cause retinal detachment. The underlying changes within the retina that lead to the proliferation of blood vessels are not well understood. One of the factors that leads to changes in retinal blood vessels is an increase in growth factors from cells within the retina called Muller cells. Muller cells are vital for the normal function of ....Diabetes is the leading cause of blindness in the working population. In some patients with diabetes, blood vessels within the retina proliferate, haemorrhage or cause retinal detachment. The underlying changes within the retina that lead to the proliferation of blood vessels are not well understood. One of the factors that leads to changes in retinal blood vessels is an increase in growth factors from cells within the retina called Muller cells. Muller cells are vital for the normal function of the retina and are known to be abnormal late in diabetes. They may also be dysfunctional early in diabetes and could play a significant role in causing the early changes seen in diabetes. Therefore a good understanding of how Muller cells change and the time at which they change is vitally important to gain a better understanding of the defects that are associated with diabetes. Furthermore, an understanding of the basic underlying cellular changes that occur in dibaetes will aid the development of more specific therapeutic agents in the future.Read moreRead less
Hearing Protection Conferred By P2X2 Receptor Signaling In The Cochlea

Summary
Hearing loss from noise damage and ageing is the principal sensory disability in our society. This project will determine the contribution of the P2X2 receptor to protection from noise-induced hearing loss. We have found that P2X2 knockout mice have minimal temporary threshold shift. We will investigate the physiological basis for this and determine why this mouse model has greater hearing loss with intense sound and faster age-related hearing loss compared with wildtype controls.
