Differential requirements for the induction of interleukin 2 responsiveness in L3T4+ and Lyt-2+ T cell subsets
نویسندگان
چکیده
Minimal requirements for the induction of interleukin 2 (IL-2) responsiveness in purified subsets of murine T lymphocytes have been investigated. Whereas Lyt-2+ cells could be induced to IL-2-dependent growth by lectin, phorbol ester, or calcium ionophore, none of these stimuli was by itself sufficient for L3T4+ cells. The latter cells could, however, be induced to respond to IL-2 by combinations of lectin plus phorbol ester or ionophore plus phorbol ester (but not lectin plus ionophore). Under optimal conditions, growth of L3T4+ cells (like Lyt-2+ cells) was independent of accessory cells and cell-cell contact.

In an effort to elucidate the role of intrathymic Ia-bearing antigen-presenting cells (APC) on the development of the class II-restricted T cell repertoire, we examined the effect of neonatal anti-I-A treatment on both intrathymic and splenic APC function; on the generation of Lyt-2-,L3T4+, Lyt-2+,L3T4-, and Lyt-2+,L3T4+ T cells; and on the development of class I- and class II-specific T cell f...
متن کاملBoth L3T4+ and Lyt-2+ helper T cells initiate cytotoxic T lymphocyte responses against allogenic major histocompatibility antigens but not against trinitrophenyl-modified self
This study characterizes the T helper (Th) cells that initiate primary cytotoxic T lymphocyte (CTL) responses against allogeneic and trinitrophenyl (TNP)-modified self class I major histocompatibility (MHC) determinants. We show that two distinct Th cell subsets participate in allospecific CTL responses: (a) an L3T4+,Lyt-2- class II-restricted Th cell population, and (b) an L3T4-,Lyt-2+ class I...
متن کاملProperties of purified T cell subsets. II. In vivo responses to class I vs. class II H-2 differences
Highly purified populations of C57BL/6 (B6) L3T4+ and Lyt-2+ T cell subsets were compared for their capacity to exert alloreactivity to class I vs. class II H-2 differences in vivo. B6 Lyt-2+ cells responded strongly to the class I different mutant, bm1, as manifested by DNA synthesis in the spleen of irradiated mice followed by entry of blast cells into thoracic duct lymph, induction of spleno...
متن کاملEffective protection against Listeria monocytogenes and delayed-type hypersensitivity to listerial antigens depend on cooperation between specific L3T4+ and Lyt 2+ T cells.
Selected L3T4- and Lyt 2- T-cell subpopulations from Listeria monocytogenes-infected mice were transferred into syngenic recipients, and their capacity to adoptively mediate protection against L. monocytogenes and delayed-type hypersensitivity to listerial antigens was determined. Both functions were markedly reduced by pretreatment of cells with either anti-L3T4 or anti-Lyt 2.2 antibodies plus...
متن کاملDifferent roles for L3T4+ and Lyt 2+ T cell subsets in the control of an acute herpes simplex virus infection of the skin and nervous system.
Rat monoclonal antibodies were used to deplete selectively Lyt 2 (cytotoxic) and L3T4 (helper) T cell populations in vivo. These antibodies produced greater than 95% depletion of the respective T cell subset as determined by fluorescent antibody and cytofluorographic analyses. Antibody-treated mice were infected in the ear pinna with herpes simplex virus (HSV) and the induction of virus-specifi...
