Abstract/OtherAbstract:
Visceral leishmaniasis, caused by the protozoan parasite Leishmania donovani, is characterized by the loss of ability of the host to generate an effective immune response. In the present study, the comparative potential of CXC chemokines, interferon-gamma-inducible protein-10 (IP-10) and interleukin-8 (IL-8) in restricting Leishmania donovani infection via the release of nitric oxide and proinflammatory cytokines was studied in an in vitro model. Nitric oxide, a crucial mediator for IP-10-mediated leishmanicidal activity, was found to be dependent on inducible nitric oxide synthase 2 (iNOS2) expression and was linked to the mitogen-activated protein kinases (MAPK) signaling pathway. Further, IP-10 was also able to abrogate the survival of Leishmania in an in vivo model of visceral leishmaniasis by restoration of Th1 cytokines and nitric oxide. Thus, this study strongly demonstrates that IP-10, like CC chemokines, is involved in rendering a protective response in visceral leishmaniasis via up-regulation of proinflammatory mediators.
