Funded Activity Summary

Cell death by a special process called apoptosis is a means of deleting unwanted and harmful cells from the body. Extensive apoptosis occurs during foetal development which is required to get rid of many excess cells produced during the growth of the embryo. Selective apoptosis is also essential for the formation of different tissues and organs in developing foetus. In the adult, apoptosis is required for proper functioning of the immune system, to remove virus infected and cancer cells and in general to maintain the correct number of cells in the body. As such, misregulated apoptosis is associated with the pathogenesis of a wide array of diseases such as autoimmune diseases, many forms of cancer and neurodegenerative disorders (such as Alzheimer's and Parkinson's diseases), heart disease, ischaemia and other conditions. To understand, manage and treat disorders that result from aberrant apoptosis, we need to know at molecular and cellular level, how apoptosis is brought about and how it is regulated. We have been studying these processes in detail for several years. Central to the apoptotic execution of cell death are a group of proteases that target many cellular proteins for specific cleavage. The activation of these proteases is the crucial step in the initiation of apoptosis and therefore each cell has developed complex ways to control this process. In the present proposal, we aim to study regulation of caspases that are involved in developmental apoptosis. Furthermore, we plan to identify proteins that are responsible for the regulation of caspase activation.
