Abstract
Background:
The transplantation of bone marrow mesenchymal cells (BMSCs) has been
shown to be an effective mean for treating sepsis-related organ damage. Pytoptotic cell death, in turn, has
recently been identified as a key driver of sepsis-related damage. At present, there are few studies on the
effect of BMSC transplantation on pyroptotic cell death.
Objective:
We explored the ability of BMSCs to attenuate hepatic damage in a pyroptosis-related manner
in a rat model of lipopolysaccharide (LPS)-induced liver injury.
Methods:
Following injury modeling and BMSC transplantation, we assessed the expression of the NLR
family, pyrin domain containing 3 (NLRP3) inflammasome, and key downstream pyroptosis-related signaling
molecules.
Results:
It was found that BMSC transplantation was sufficient to significantly improve rat survival after
LPS injection. A significantly reduced expression of the pyroptosis-related proteins NLRP3, caspase-1,
IL-1β, and IL-18 in rats that had undergone BMSC transplantation compared to control animals was observed.
Notably, this activity was superior to single-agent administration of the NLRP3 inhibitor
MCC950.
Conclusion:
Our data suggest that BMSC transplantation may alleviate LPS-induced hepatic damage by
suppressing the activation of the NLRP3 inflammasome and the induction of pyroptotic cell death.
