Abstract

Cytotoxic lymphocytes are immune cells, which recognise and kill virus-infected or cancer cells. Perforin is essential for the activity of cytotoxic lymphocytes. The loss of perforin function results in an inherited immune deficiency, or may lead to the development of cancer. Despite a key role of perforin, its mechanism of action and the regulation of activity are unknown. I propose to elucidate these aspects of perforin biology. This is important for understanding immune regulation in humans.
