Mention the role of TH and CTLs?
cytotoxic T lymphocytes/cells (CTLs)
B cells and T cells differ in their mechanisms of antigenrecognition. While B cells recognize the antigen by interactingwith the epitope on their own, T cells recognize the antigenonly when the epitope is “presented” by one of the specializedantigen-presenting cells.
/distinct
Antigen-presenting cells (APCs) are a group of immune cells thatmediate the cellular immune response by processing and presentingantigens for recognition by certain lymphocytes such as T cells.
Classical APCs include dendritic cells, macrophages, and B cells.
TCR?
Locus: a particular position or place where something occurs or is situated.
