Immune System Uses Vitamin B to Recognize Infection, University of Melbourne, Monash University Study

An Australian research team has discovered how specialised immune cells recognise products of vitamin B synthesis that are unique to bacteria and yeast, triggering the body to fight infection. The finding opens up potential targets to improve treatments or to develop a vaccine for tuberculosis. The study, jointly led by the University of Melbourne and Monash University and published today in the journal Nature, has revealed for the first time that the highly abundant mucosal associated invariant T cells (MAIT cells), recognise products of vitamin B synthesis from bacteria and yeast in an early step to activating the immune system.
