Detailed explanation-1: -IMMUNE RESPONSE | General Features APCs may interact with two classes of lymphocytes: the B or bone marrow-derived lymphocytes, but especially with the T or thymus-derived lymphocytes. APCs process antigen to a form which is recognized by T cells.
Detailed explanation-2: -An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen bound by major histocompatibility complex (MHC) proteins on its surface; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs).
Detailed explanation-3: -B-lymphocytes, macrophages, and dendritic cells are the three primary antigen-presenting cells.
Detailed explanation-4: -Although dendritic cells are important in presenting antigen, particularly to initiate primary immune responses, macrophages are the professional APC type most prominent in inflammatory sites and specialized for clearing necrotic and apoptotic material.
