Objective Immune dysfunction, including prominent apoptosis of immune cells and decreased functioning of the remaining immune cells, plays a central role in the pathogenesis of sepsis. Sterile α and HEAT/armadillo motif-containing protein (SARM) is implicated in the regulation of immune cell apoptosis. This study aimed to elucidate SARM contributes to sepsis-induced immune cell death and immunosuppression. Methods A mouse model of polymicrobial sepsis was generated by cecum ligation and puncture (CLP). SARM gene and protein expression, caspase 3 cleavage and intracellular ATP production were measured in the mouse spleens. Results CLP-induced polymicrobial sepsis specifically attenuated both the gene and protein expression of SARM in the spleens. Moreover, the attenuation of SARM expression synchronized with splenocyte apoptosis, as evidenced by increased caspase 3 cleavage and ATP depletion. Conclusions These findings suggest that SARM is a potential regulator of sepsis-induced splenocyte apoptosis.
