Question

These cells can be artificially equipped with a chimeric antigen receptor (15[1])in a form of cancer immunotherapy. (-5[1])The FOXp3 protein is important for the development (-5[1])of one population of these cells. The surface markers of these cells dictate which of the two MHC classes they interact with. (15[1])These (15[1])CD3-positive (15[1]-5[1])cells are initially double-positive during development, expressing both (*) CD4 and CD8 before selecting one, A “helper” variety of these cells secrete cytokines to communicate with other immune cells. (-5[1])Cancer cells can be killed by the “cytotoxic” variety of these cells. (10[1])For 10 points, name these immune cells which mature in the thymus, unlike B cells. ■END■ (10[4]0[1])

ANSWER: T cells [or T lymphocytes; accept cytotoxic T cells or helper T cells or memory T cells or CD4 T cells or CD8 T cells; prompt on lymphocytes or immune cells]
