Normal mouse spleen cells are not capable of mounting a primary cytotoxic T lymphocyte (Tc) response to non-H-2 alloantigens in vitro, although a good secondary H-2-restricted response is observable after in vivo immunization of the responder animals. Suppressor cells are generated in such a primary responses provided a Mls incompatibility exists between the responder and stimulator. These supp...

T lymphocyte lines have been established, with the addition of interleukin-2 (IL-2), from the synovial fluid (SF) of patients with arthritis. Characterisation of seven of these SF-derived T cell lines showed them to be T3+, T11+, and to contain a significant proportion of T8+ cells (mean 41%). The proportion of T4+ cells varied among the lines, with a mean T4+/T8+ ratio of 0.6. A significant au...

In the present study we used hydrocortisone (HC) treatment in vivo as a probe to analyze two different in vitro systems for the regeneration of cytotoxic T lymphocyte (CTL), namely the antifibroblast reaction (AFR) and the mixed lymphocyte culture (MLC) system. We found that cells remaining in the thymus after HC treatment had increased reactivity in these two systems. However, the same treatme...

CD45-AP specifically associates with CD45, a protein tyrosine phosphatase essential for lymphocyte differentiation and antigen receptor-mediated signal transduction. CD45 is thought to mediate antigen receptor signaling by dephosphorylating regulatory tyrosine residues on Src family protein tyrosine kinases such as Lck. However, the mechanism for regulating CD45 protein tyrosine phosphatase act...

Bone marrow cells from C3H (H-2k) mice, a strain that does not exhibit cross-reactive lysis of trinitrophenyl (TNP)-modified allogeneic targets, were allowed to mature in heavily irradiated (B6 times C3H)F1 (H-2b/k) recipients, an F1 hybrid that does demonstrate cross-reactive lysis. Spleen cells from these chimeric mice were removed after 3-4 mo and by H-2 typing shown to be of C3H origin. The...

PROBLEM During pregnancy, the endometrium of the ewe secretes a progesterone-induced member of the serpin superfamily of serine proteinase inhibitors called ovine uterine serpin (OvUS) that has immunosuppressive properties. METHOD Review of the literature. RESULTS AND CONCLUSIONS OvUS inhibits a wide variety of immune responses, including mixed lymphocyte reaction, mitogen-stimulated lympho...

Nanomedicine, the medical application of nanotechnology, promises a seemingly limitless range of applications from drug delivery to adjuvants and therapeutics. Our current research is focused on natural polymer-based liposome adjuvants. With the aim of inducing protective and long-lasting immunity, the immunological adjuvant activity of Rehmannia glutinosa polysaccharide liposome (RGPL) was inv...

Interaction of CD28/CTLA-4 on T cells with B7 on antigen-presenting cells constitutes an important costimulatory signal for T cells and is responsible for cyclosporin A-resistant interleukin 2 (IL-2) gene expression and potentially also for prevention of anergy induction after T cell receptor triggering. In this paper, we demonstrate that addition of a monoclonal antibody to B7, which blocks B7...

AIM To corroborate and investigate the nature of Hodgkin/Reed-Sternberg cells (H/R-S) of various subtypes of Hodgkin's disease. METHOD Single H/R-S cells were micro-picked from frozen sections of tissues affected by Hodgkin's disease. The DNA from these cells was amplified by the polymerase chain reaction (PCR) with immunoglobulin heavy chain (IgH) gene FRIIIa/JH primers and light chain gene ...
