title: [Characteristics of the T-lymphocytes interacting with hematopoietic stem cells: the expression of Lyt-3 antigen].
abstract: The lymph node cells were treated with monoclonal anti-Lyt-3 antibodies (anti-Lyt-3) and complement. Their interaction with colony-forming units (CFU) of bone marrow was studied. Anti-Lyt-3 did not affect the activity of T-lymphocytes, which changed the pattern of syngenic CFU differentiation in spleen of irradiated mice. On the contrary, the activity of T-lymphocytes, which inactivated proliferation and differentiation of non-syngenic CFU in spleen, was decreased. In the peritoneal cavity of irradiated mice antibodies did not affect the activity of T-lymphocytes which suppressed the colony-formation of non-syngenic stem cells and switched off the activity of T-lymphocytes that stimulated syngenic CFU colony-formation. The subpopulation characteristics of regulatory and effector T-cells has been analysed.
