Popis: In vivo neutralization of interleukin-10 (IL-10) with an anti-IL-10 monoclonal antibody resulted in up to 10-fold fewer bacteria in the spleens of BALB/c mice infected with the virulent Brucella abortus strain 2308. In vitro neutralization of endogenous IL-10 in brucella antigen-stimulated cultures of splenocytes from infected mice resulted in increased gamma interferon production in these cultures, whereas exogenous recombinant IL-10 inhibited the ability of peptone-elicited peritoneal macrophages to control intracellular brucellae. These data suggest that IL-10 may be downregulating the immune response to B. abortus by affecting both macrophage effector function and the production of the protective Th1 cytokine gamma interferon.
