Suppression of cytophilic antibody ('arming' factor) in the sera of patients with prostatic cancer by human seminal plasma.
The 'arming' of normal peripheral blood leukocytes (PBL) by cytophilic antibody in the sera of prostatic cancer patients is suppressed by pretreatment of PBL with normal human seminal plasma (HuSPl). Suppression of cytophilic antibody by HuSPl extends the spectrum of immunologic reactions on which SPl has an immunosuppressive effect and may provide further insight into the possible role of SPl in the natural history of prostatic cancer.
