Salmonella Typhimurium, a bacterial pathogen with high metabolic plasticity, can adapt to different environmental conditions; these traits enhance its virulence by enabling bacterial survival. Neutrophils play important roles in the innate immune response, including the production of microbicidal reactive oxygen species (ROS). In addition, the myeloperoxidase in neutrophils catalyzes the...

Acrylamide (AA) is an important product of the Maillard reaction. Studies have demonstrated that AA caused oxidative stress damage in liver, which in turn triggered an inflammatory response, and the activation of NOD-like receptor protein-3 (NLRP3) inflammasome played a key factor in regulating inflammation. Therefore, we hypothesized NLRP3 inflammasome activation was involved in AA-induced...
