Summary
To fight infection or cancer the body produces specialized cells called cytotoxic lymphocytes (CLs) which target and eradicate abnormal cells. The number of CLs increases dramatically during infection, and decreases following infection. How this population decrease is controlled is not fully understood, but we propose that a protein used by the CL to kill targets also triggers suicide of the CL after it has destroyed a certain number of targets. How this is achieved is the focus of this project.

Summary
A heart attack is associated with an increase in free radicals and calcium in heart muscle cells. The function of the L-type calcium channel, a protein responsible for calcium entry into cells, is altered by free radicals and this contributes to the development of heart disease. We now have considerable proof of concept that a peptide derived against the L-type calcium channel can decrease heart injury. We will optimise efficacy and delivery of the peptide to prevent heart failure.
