Phosphatidylinositol 3-kinase, MEK-1 and p38 mediate leptin/interferon-gamma synergistic NOS type II induction in chondrocytes.


In a previous study, we established that leptin acts synergistically with interferon-gamma in inducing nitric oxide synthase type II in cultured chondrocytes via Janus kinase-2 activation. However, the exact molecular mechanism that accounts for this synergism is not completely understood. The aim of the present study was to further delineate the signalling… (More)
