Core Tip

Core Tip: We explored the role of the p38 mitogen-activated protein kinase pathway in the tumor necrosis factor-alpha-induced inflammation and apoptosis of pulmonary microvascular endothelial cells in vitro and verified the effect of SB203580-mediated p38 inhibition on severe acute pancreatitis-related acute lung injury in rats. p38 mitogen-activated protein kinase overactivation promoted tumor necrosis factor-alpha-induced inflammatory cytokine expression and pulmonary microvascular endothelial cell apoptosis in vitro. SB203580 improved severe acute pancreatitis-related acute lung injury by downregulating P-p38, NFκB, P-SATA3 and Myd88 and upregulating IκB and HO-1, which alleviated inflammation and apoptotic cell death in rats.
