LACC1 contributes to inflammation and cognitive disorder after stroke via the AMPK/NLRP3 pathway.

Abstract

The current study aimed to investigate the effects of LACC1 on cognitive disorder due to stroke, as well as its underlying mechanism. LACC1 promoted inflammation and aggravated cognitive impairment in a mouse model of stroke. In an in vitro model of stroke, inhibition of LACC1 reduced inflammation and ROS‑induced oxidative stress by activating AMP‑activated protein kinase (AMPK) expression and suppressing NLPR3 expression. Furthermore, our studies revealed that inhibition of AMPK activity reduced the effects of si‑LACC1 on cognitive disorder in mice after stroke via the AMPK/NLPR3 pathway. AMPK activation also reduced the effects of LACC1 on inflammation and ROS‑induced oxidative stress via the NLPR3 pathway in the in vitro model that we evaluated. Our study suggests that LACC1‑aggravated inflammation causes cognitive impairment after stroke via the AMPK/NLRP3 pathway, which may provide a new therapeutic target for stroke and other neurological diseases and their associated complications. In sum, we identified an important role and regulatory mechanism for LACC1 in maintaining stroke‑induced cognitive disorder via the AMPK/NLRP3 pathway.
