T-cell phenotypes in chemically induced leukemia in mice
T-cell leukemias were induced in adult BDF mice by a single i.v. injection of 50 mg kg-1 of methylnitrosourea (MNU). Leukemic cells from the thymus and other organ sites showed the theta antigen and were peanut-negative, but were heterogeneous with respect to Lyt-1 and Lyt-2. The acute cytotoxic effect of the MNU showed no preferential toxicity to a special T-cell subset in the thymus. During the latency period of leukemogenesis a continuous fall in peanut-positive cells in the thymus was found.
