However, the precise mechanisms remain largely unclear. This study investigated whether pyroptosis, a form of inflammatory programmed cell death, contributes to the impairment of colonic barrier integrity induced by\n                    <jats:italic>T. gondii<\/jats:italic>\n                    chronic infection in mice. We found that the infection resulted in pronounced pathological damage in the colon, characterised by reduced colon length, decreased expression of tight junction proteins, and elevated serum LPS levels. Interestingly, the infection activated the pyroptosis pathway, supported by the higher expression of NLRP3 (NOD\u2010like receptor thermal protein domain associated protein 3), Caspase\u20101, gasdermin D (GSDMD), GSDMD\u2010N, as well as IL\u20101\u03b2 and IL\u201018. In addition, dimethyl fumarate, an anti\u2010pyroptogenic drug, significantly attenuated the infection\u2010induced pyroptosis and colonic pathology. Notably, macrophages exhibited pyroptosis post\n                    <jats:italic>T. gondii<\/jats:italic>\n                    infection, which was attenuated by DMF treatment. Overall, our results uncover that pyroptosis is vital for the impairments of gut barrier integrity post\n                    <jats:italic>T. gondii<\/jats:italic>\n                    chronic
