    In vivo and in vitro studies show that lymphocytes can specifically target and reject foreign tissues. This immune response is precise, distinguishing between similar and dissimilar allogeneic tissues.

    Area of Science:

    • Immunology
    • Transplantation Biology

    Background:

    • Immune responses are critical for tissue rejection.
    • In vivo sensitization leads to accelerated rejection of specific allogeneic tissues.

    Purpose of the Study:

    • To investigate the specificity of lymphocyte-mediated tissue rejection in vitro.
    • To compare in vitro lymphocyte sensitization with in vivo immune responses.

    Main Methods:

    • In vitro sensitization of lymphocytes against target cells.
    • Assessment of lymphocyte-mediated cytotoxicity against isogeneic and allogeneic target cells.

    Main Results:

    • In vitro sensitized lymphocytes effectively destroy isogeneic target cells.
    • In vitro sensitized lymphocytes demonstrate specific differentiation between distinct allogeneic target cells, mirroring in vivo responses.

    Conclusions:

    • In vitro lymphocyte sensitization models in vivo immune responses.
    • Lymphocytes exhibit specific allogeneic recognition and cytotoxic capabilities.
