Spontaneous cytotoxicity of human peripheral blood mononuclear cells for the lymphoblastoid cell line CCRF-CEM: augmentation by bacterial lipopolysaccharide.

Spontaneous cell-mediated cytotoxicity (SCMC) of human peripheral blood mononuclear cells for a poor target, CCRF-CEM, a lymphoblastoid cell line, was rapidly and markedly elevated by E. coli lipopolysaccharide (LPS). SCMC for K562, a myeloid cell line sensitive to SCMC, was only slightly elevated by LPS. The cytotoxicities of both adherent and non-adherent mononuclear cells for CCRF-CEM were elevated. A response to LPS was found in Fc gamma R-positive and Fc gamma R-negative T cells. LPS increased the binding of non-adherent cells to both targets, but analysis of the binding suggests that a subsequent step, either triggering of the cytotoxic mechanisms or susceptibility of the target was the basis for the increased SCMC.

Risk factors for HIV infection in homosexual men: the Cleveland men's study of risks in a low-prevalence area.

Detailed questionnaires concerning alcohol and drug use, sexual practices, and medical history were completed by 301 homosexual men living in the Cleveland metropolitan area. Their sera were subsequently tested for antibodies to the human immunodeficiency virus. Fifty-six (18.6%) were seropositive. In a univariate analysis, age, drug use, and four specific sexual practices were associated with seropositivity. In a multiple logistic regression analysis, intravenous drug use and receptive anal-genital sex remained independent predictors of seropositivity.
