Introduction
Antigen Presentation Antigen presentation plays a pivotal role in the immune system through which pathogenic antigens are processed and coupled along with major histocompatibility complex (MHC), and presented to T cells for their effector response. Macrophages, B cells and dendritic cells are the primary antigen presenting cells (APC’s). Intracellular antigens generated by viruses, or some cytoplasmic bacterial antigens are digested by the host cells and coupled with MHC Class I by Transporter associated with antigen Processing complex (TAP), which transports them to the cell surface and presents to CD8+ cytotoxic T cells (Germain, R 1994). These cells elicit a ...
