Research Interests

Michelle Linterman received her PhD in Immunology from the Australian National University in Canberra, where she investigated a novel mechanism of immunological tolerance; a phenomenon by which the immune system fails to respond to an antigen. She is currently a Group Leader at the Babraham Institute and her principle research focus is on how the immune system responds to vaccination.

Group Research

When higher organisms are infected by pathogens the immune system responds with the coordinated activation of many different cell types, each with their own specific role to bring about pathogen clearance, and subsequently generate immunological memory. Within the adaptive immune system helper CD4+ T cells and B cells specific for the infectious organism are recruited to become activated effector cells and a proportion of these cells will go on to become memory cells that are able to respond quickly to future infections.

Germinal centres are sites within tissues such as the tonsils, spleen and lymph nodes where B cells proliferate and differentiate during a normal immune response to an infection. Because of the central role of the germinal centre in generating immunological memory, a potent germinal centre response is critical for a successful response to vaccination. With advancing age, the size of the germinal centre response and the efficacy of vaccination diminish, and T cells are one of the primary contributors to this decline.

Our research is focused on understanding the cellular and molecular changes that occur in T cells with age that contribute to the age-dependent decline in the germinal centre response.
