Summary
Dendritic cells (DC) of the immune system utilise specific receptors to sense danger signals from their environment. We identified a DC danger receptor, Clec9A, which recognizes and induces immunity to “dangerous” dead cells eg. infected cells or killed tumour cells. We will investigate how DC use Clec9A to process “dangerous” dead cells, and the factors that control the potency of this immune response. This will enable us to develop novel immunotherapies for infectious diseases and cancer.

Summary
The immune system senses danger from infectious diseases, damaged and dead cells. We identified a danger receptor, Clec9A, on a specialised cell type of the immune system in mice and humans. Clec9A recognizes and induces immunity to dangerous dead cells. Delivering vaccines to Clec9A improves vaccine responses. We will investigate how Clec9A recognises and reacts to danger, and how we can mimic this recognition to improve vaccine design.
