  • Title: The effect of human spermatozoa on antigen and mitogen induced blastogenesis.
    Author: Marcus ZH, Herman JH, Hess EV.
    Journal: Arch Androl; 1978; 1(1):89-97. PubMed ID: 742945.
    Abstract:
    In an attempt to identify factors capable of specifically or nonspecifically modulating results in an in vitro blastogenic assay system, studies were performed evaluating cell mediated immune response to human spermatozoa. Spermatozoa were capable, on a dose dependent basis, of both inhibiting and stimulating normal lymphocyte DNA synthesis as well as suppressing mitogen-induced response. Pretreatment of spermatozoa with neuraminidase and alpha-methyl-D-mannoside abrogated suppressive properties on spontaneous and/or mitogen-induced stimulation. Such suppressive activity on mitogen-induced response was observed using B and T-cell enriched populations. Inhibitory properties were not evident using intact cell populations stimulated by specific antigen. It is suggested that: (1) receptors on spermatozoa bind lectin; and (2) such receptors can be inactivated by enzymes having glycoprotein specificity.
