IL-12p70, a 70- to 75-kDa heterodimer consisting of disulfide-bonded 35-kDa (p35) and 40-kDa (p40) subunits, enhances Th1 development primarily by its ability to induce IFN-gamma production by NK and Th1 cells. Although homodimers of the p40 subunit of IL-12 are potent IL-12 receptor antagonists in some systems, we have reported that p40 homodimer may accentuate alloreactive CD8+ Th1 function. ...
Lipopolysaccharide (LPS) increases the production of interleukin-12 (IL-12) from mouse macrophages via a kappaB site within the IL-12 p40 promoter. In this study, we found that retinoids inhibit this LPS-stimulated production of IL-12 in a dose-dependent manner. The NFkappaB components p50 and p65 bound retinoid X receptor (RXR) in a ligand-independent manner in vitro, and the interaction inter...
Resistance to infection by Leishmania major has been associated with the development of a Th1 type response that is dependent on the presence of interleukin 12 (IL-12). In this work the involvement of this cytokine in the response to infection by L. braziliensis, a less virulent species in the mouse model, was evaluated. Our results show that while interferon (IFN-gamma) deficient (-/-) mice in...
