Penning decoction ameliorated pyroptosis in mice with lipopolysaccharide-induced endometritis through inhibition of the TLR4/NF-κB/NLRP3 pathway.

OBJECTIVES: Endometritis, stemming from bacterial infection, manifests as persistent inflammation and may cause infertility. Penning decoction (PND) has been approved for clinical treatment of patients with endometritis. However, the mechanism by which it prevents endometritis remains unknown. This study aimed to examine the impact of PND on lipopolysaccharide (LPS)-induced endometritis and elucidate the underlying mechanisms involved. METHODS: . RESULTS: . Treatment with PND or serum containing PND could significantly ameliorate LPS-induced pyroptosis by inhibiting the activation of the TLR4/NF-κB/NLRP3 signaling pathway. CONCLUSION: Our results demonstrated that PND may improve LPS-induced endometritis by inhibiting the TLR4/NF-κB/NLRP3 pathway, which provides a potentially effective drug for the clinical treatment of endometritis.
