Antigen presentation for B cell recognition, illustration
Antigen presentation for B cell recognition, illustration. Interaction between a follicular dendritic cell (FDC, blue) and a B lymphocyte cell (pink), two components of the body's immune system. Both are types of white blood cell. B cells recognise a specific site on the surface of pathogens or foreign objects (antigens, dark blue), bind to it to become activated, and subsequently attract other cells to eliminate that antigen. Both dendritic cells and B cells are antigen-presenting cells (APCs), meaning they present antigens which may be recognised by T lymphocytes for antigen elimination.
