B-cell function in common variable immunodeficiency: suppression of in vitro anti-sheep erythrocytes antibody production by T cells and monocytes.

abstract：:The effect of invasive bacteria on the release of proinflammatory mediators (oxygen radicals, leukotriene release) from human polymorphonuclear neutrophils was studied. Bacterial stimuli were used including genetically cloned invasive Yersinia enterocolitica strains 108-P (bearing the phagocytosis-resistance plasmid) ...
