For 10 points, name these lymphocytes that mature in the thymus, as contrasted with similar cells that mature in the bone marrow, B cells.
The development and function of one subtype of these cells is controlled by the transcription factor FOXP3. Although not CD79, one cluster of differentiation in these cells contains the ITAM motif; phosphorylation of that motif by Lck allows ZAP70 to bind to their zeta chain. Although not natural killer cells, another subtype of these cells releases granzymes and perforin. These cells are distinguished from ones similar in function based on the presence of a namesake receptor, which recognizes antigens bound to MHC molecules. Their subtypes are distinguished by whether they express CD4 or CD8, which identify the helper and cytotoxic types.
