title: [Heterogeneity of immunologic memory T cells specific for H-2 antigens and detection of their receptors].
abstract: The in-vivo-induced memory T cells (MC) of mice, specific to H-2 antigens, are assayed by the generation of the secondary cytotoxic T lymphocytes (CTL) in mixed lymphocyte culture (MLC) activated by heat-killed stimulator cells. The MC are shown to adhere selectively to the corresponding target monolayer that gives rise to both the loss of MC activity in the population of non-adherent lymphocytes and gain in MC activity in the population adherent and eluted from the same monolayer. In addition to the revealing of MC H-2 antigen-binding receptors, the absorption-elution technique allows the separation of the MC into two categories: secondary CTL precursors bearing these receptors, and secondary amplifier cells non-adherent to the monolayer and assayed by promotion of the CTL generation from the primary precursors activated in MLC by heated stimulators. The difference in the receptor properties between the primary and secondary CTL precursors raises the possibility that the MC are generated not only in the amplifier cell population but also in the independent CTL precursor population.
