    Summary
    This summary is machine-generated.

    Rabbit complement significantly impacts monocyte cytotoxicity. Antibodies against monocytes, B cells, and T cells were found in kidney allografts, with some reactions being monocyte-specific.

    Area of Science:

    • Immunology
    • Transplantation immunology

    Background:

    • Monocyte cytotoxicity plays a role in transplant rejection.
    • Understanding antibody specificities is crucial for allograft survival.

    Purpose of the Study:

    • To investigate the role of complement in monocyte cytotoxicity.
    • To characterize antibodies found in kidney allograft eluates.
    • To identify monocyte-specific antibody reactions.

    Main Methods:

    • Monocyte cytotoxicity assays using rabbit complement.
    • Analysis of eluates from kidney allografts.
    • Antibody blocking studies using anti-DR and anti-beta 2-microglobulin antisera.
    • Assessment of 56 alloantisera.

    Main Results:

    Related Experiment Videos

    • Monocyte cytotoxicity was highly dependent on the chosen rabbit complement.
    • Kidney allograft eluates contained antibodies against monocytes, B cells, and T cells.
    • Monocyte-specific reactions were not blocked by chicken anti-DR but were abolished by turkey anti-beta 2-microglobulin.
    • 52% of reactions were blocked by anti-DR, and 25% appeared monocyte-specific.

    Conclusions:

    • Complement selection is critical for studying monocyte cytotoxicity.
    • Beta 2-microglobulin is involved in monocyte-specific antibody recognition.
    • A significant portion of antibodies in kidney allografts target monocytes, independent of DR antigens.
