Does leptin treatment ameliorate acute lung injury in rats with cerulein-induced acute pancreatitis?
Exogenous leptin attenuates inflamma-tory changes, and reduces pro-inflammatory cytokines, nitric oxide levels, and CD40 expression in cerulein-induced AP and may be protective in AP associated ALI.
Such elevation of TGF-beta may increase the stability of plaques by inhibiting T cell responses and macrophage activation and by stimulating collagen synthesis. This new finding could be important in the regulation of immune activity, inflammation and fibrosis in the atherosclerotic plaque.
