Research Abstract |
Inflammasome activation is responsible for the programmed cell death pytoptosis and cytokine production including IL-1 beta and IL-18. Based on our results, it was clarified that AIM2, type I IFN and kinase signals such as Syk are involved in the inflammasome activation induced by Listeria monocytogenes. Furthermore, we narrowed down the responsible region of listeriolysin O for inflammasome activation as a bacterial factor and revealed that the amino acid region from 204 to 254 of listeriolysin O is important for the activity.
