Epitope (Antigen determinant) | Portion of an antigen that is reactive with a specific antibody or T-Cell receptor |
Antigen-presenting cell (APC) | A macrophage, dendritic cell, or B cell that presents processed antigen peptides to a T cell |
Autoantibody | an antibody that reacts to self antigens |
B cell | A lymphocyte that has immunoglobulin surface receptors, produces immunoglobulin, and may present antigens to T cells |
Cell-mediated immunity (CMI) | immunity resulting from direct interaction with antigen specific T cells |
Cytokine | a soluble immune response modulator produced by leukocytes |
Lymphocyte | a subset of nucleated cells found in the blood that are involved in the immune response |
Leukocyte | a nucleated cell found in white blood cells |
