WebJan 7, 2024 · The accessory receptors of cell-mediated immunity are CD2, CD3, CD4, CD8, CD28, and integrins. Humoral immunity recognizes the unprocessed antigens. In … Cellular immunity protects the body through: • T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens; • Macrophage and natural killer cell action: enabling the destruction of pathogens via recognition and

WebFor example, B cell markers, such as chemokine (C-X-C motif) ligand (CXCL)13 and B cell activation factor (BAFF), have been shown to be elevated in antibody-associated CNS … WebSome decrease in immunity occurs with aging. For example, in older adults, the thymus tends to produce fewer naive T cells; thus, fewer T cells are available to respond to new antigens. The total number of T cells does not decrease (because of oligoclonality), but these cells can recognize only a limited number of antigens.
