Özet

Uncontrolled infection and increased inflammatory mediators might cause systemic inflammatory response. It is already known that Cannabinoid Type 2 (CB2) receptors, which are commonly expressed in immune cells and in many other tissues, have an effect on the regulation of immune response. In the present study of ours, the effects of CB2 receptor agonist JWH-133 was investigated on cecal ligation and puncture (CLP)-induced polymicrobial sepsis model in rats. In the present study, Sprague-Dawley rats were divided into 5 groups (i.e. the Sham, CLP, JWH-133 0.2 mg/kg, JWH-133 1 mg/kg, and JWH-133 5 mg/kg Groups). Except for the Sham Group, the CLP-induced sepsis model was applied to all groups. The histopathological damage in brain, lung, liver and, heart was examined and the caspase-3, p-NF-kappa B, TNF-alpha, IL-1 beta and IL-6 levels were determined immunohistochemically. The serum TNF-alpha, IL-1 beta, IL-6, IL-10 levels were examined with the ELISA Method. The JWH-133 treatment decreased the histopathological damage in brain, heart, lung, and liver and reduced the caspase-3, p-NF-kappa B, TNF alpha, IL-1 beta, IL-6 levels in these tissues. In addition to this, JWH-133 treatment also decreased the serum TNF-alpha, IL-1 beta, IL-6 levels, which were increased due to CLP, and increased the anti-inflammatory cytokine IL-10 levels. In the present study, it was determined that the CB2 receptor agonist JWH-133 decreases the CLP-induced inflammation, and reduces the damage in brain, lung, liver and heart. Our findings show the therapeutic potential of the activation of CB2 receptors with JWH-133 in sepsis.
