Scientists have now discovered the origin of immune cells (our body’s defence mechanism). 'Follicular dendritic cells' (FDCs) are not blood cells and their origin has been a mystery until now. They play a critical role in allowing us to fight infections and create a strong armory of antibodies for future use. FDCs first make sure that our antibody generating B cells receive samples of an invading organism. They then help to identify and nurture the B cells that manufacture the highest quality antibodies. As earlier perceived many of our immune cells arise out of bone marrow but FDC’s arise from
