Inflammation is often a nearby immune response to infection and injury. PFOA has been identified to induce inflammation by elevating the expression of proinflammatory cytokines tumor necrosis issue and interleukin-1 and IL-6 inside the spleen and mast cells [38, 39]. In the liver, proinflammatory cytokines developed by hepatocytes participate in hepatotoxic responses [40]. A previous report showed that exposure to PFOA may sensitize hepatic parenchymal cells to other toxicants and thereby aggravate liver injury throughout acute inflammation [41]. As markers of inflammation, IL-6, CRP, and COX-2 are widely employed for estimation of several inflammatory states. In the present study, exposure to a high dose of PFOA (10 mg/kg/day) considerably enhanced the levels of IL-6, CRP, and COX-2 inside the liver tissue of mice. Our outcomes indicated a achievable role of PFOA in inflammation and hepatic injury.Figure 5: Levels of CRP (a), IL-6 (b), and COX-2 (c) in liver tissue soon after exposure to unique concentrations of PFOA.

ConclusionIn this study, we showed that oral exposure to PFOA for 14 consecutive days caused a rise in serum AST, ALT, ALP, LDH, and TBA levels and induced hepatocellular necrosis, edema, and inflammatory cell infiltration in mice.six In addition, PFOA exposure elevated lipid peroxidation and H2 O2 generation and elevated IL-6, CRP, and COX-2 levels inside the liver. These benefits indicated that PFOA could induce hepatotoxicity involving oxidative damage and inflammatory response.BioMed Investigation Internationaloxygen species,” Environmental Science and Technology, vol. 45, no. four, pp. 1638644, 2011.
