HUMAN T‐CELL LEUKEMIA VIRUS: TRANSFORMATION IN VITRO OF NONHUMAN PRIMATE T‐LYMPHOCYTES AND EXPERIMENTAL INOCULATION OF NONHUMAN PRIMATESa

T-lymphocytes from three species of New World monkeys were susceptible to transformation in vitro with human T-cell leukemia virus. Marmoset T-lymphocytes transformed in vitro with HVS or HVA, T-lymphotropic herpesviruses of New World monkeys, were also transformed with HTLV resulting in doubly transformed T-cells. This finding may provide a potential model for investigating the possible interaction between a herpesvirus and T-lymphotropic retroviruses in the clinical condition AIDS.
