title: TG and TnonG lymphocyte involvement in the proliferative response to PHA. I. Reactivity and regulatory functions of TG and TnonG subsets in the proliferative response of T lymphocytes.
abstract: Both TG and TnonG subpopulations from human peripheral blood were found to secrete helper and suppressor factors for the PHA-induced T cell proliferative response. The TnonG subpopulation contained cells which were both able to secrete helper factor and to respond by proliferation, whereas in the TG subpopulation cells with a proliferative potential could not be conclusively demonstrated. Suppressor and helper activities in TG and TnonG culture supernatants displayed a different time kinetics and were influenced by the dose of mitogen in test cultures.
