Sepsis occurs in 14-37% of patients admitted to intensive care units and sepsis associated encephalopathy (SAE) is its severe complication. In an attempt to provide insight into the question how sepsis and SAE contributes cerebral dysfunction, apoptotic cell death was investigated in hippocampal formation, centers of adult neurogenesis and main autonomic centers which are known to regulate heart rate, respiration and other visceral activities, in cecal ligation and puncture (CLP) rat model of sepsis. Vital parameters and electrophysiological changes were monitored for the confirmation of sepsis and SAE, respectively. Apoptotic cell death was evaluated by TUNEL staining, Caspase-3 immunohistochemistry and transmission electron microscope (TEM). Significantly higher number of TUNEL positive apoptotic cells in the median preoptic nucleus, subventricular zone, dentate gyrus and CA1 and CA3 regions of the hippocampal formation were observed in CLP group and Caspase-3 immunohistochemistry and TEM findings were in line with these results, suggesting that the apoptotic cell death would bare a major role in the pathogenesis of the SAE.
