英文摘要
In the present study the molecular mechanism by which Listeria virulence factors regulate host innate immune response was investigated by swapping of corresponding virulence genes among Listeria species. Peritoneal exudate macrophages were infected with various Lm mutants, and cytokine production and the inflammasome activation was monitored. Results showed that AIM2 serves as an intracellular sensor of Lm to induce inflammasome and caspase-1 activation. ASC also plays an essential role incaspase-1 activation after entry of Lm into the cytoplasm. Furthermore, it was clearly shown that the Thr233 of LLO is an important residue to induce caspase-1 activation
