Understanding recognition of vitamin B-based antigens by the immune system
Grant number: FT160100083 | Funding period: 2017 - 2021
This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still poorly understood, recognise Vitamin B-based molecules. Combining immunology with structural biology and chemistry, this project aims to understand how the immune system detects molecules produced by diverse microorganisms.
