title: Comparison of lymphocyte reactivity in patients with cancer, systemic lupus erythematosus and renal allografts.
abstract: The PHA and MLC reactivity of lymphocytes from patients with cancer, SLE or renal allografts was comparatively tested in the presence of autologous and of normal homologous serum. Sera from patients with advanced cancer, active SLE or chronic allograft rejection strongly inhibited the MLC reactivity of autologous lymphocytes. It is suggested that serum inhibitory factors might be antibodies which are directed against modified antigenic determinants of the major histocompatibility complex, and are capable of blocking T lymphocyte receptors.
