Research Interests

Cytotoxic T-lymphocytes (CTL) kill tumourogenic and virally infected cells by the polarised release of apoptotic-inducing lytic proteins stored within the ‘secretory’ lysosomes of the CTL. Secretion occurs in response to TcR activation on binding to a target cell, and involves morphological and molecular changes within the CTL including movement of the centrosome to the cell surface. These changes result in directed delivery of secretory lysosomes to specific secretory sites on the CTL membrane.

My research as a cell biologist in the laboratory of Professor Gillian Griffiths, takes morphological approaches, including electron and immunofluorescence microscopy, to investigate the cellular events and mechanisms involved in this precisely targeted secretion event.
