The effect and mechanism of freeze-dried powder ofon improving inflammatory injury of rat glomerular mesangial cells through TXNIP / NLRP3 pathway
Research article published in Heliyon (2024)
Abstract
OBJECTIVE: Diabetic kidney disease (DKD) is a common complication of diabetes mellitus. The pathophysiological changes in platelet function and the hypercoagulable state associated with DKD are closely linked to inflammatory processes. Poecilobdella manillensis (PM), a type of leech known for its anticoagulant and antithrombotic properties, has the potential to modulate the inflammatory response in DKD. This study aims to investigate the effect of freeze-dried powder of PM on improving inflammatory injury in rat glomerular mesangial cells and to explore its underlying mechanism. METHODS: Lipopolysaccharide (LPS) stimulated HBZY-1 rat mesangial cells to establish an in vitro DKD inflammation model. After the intervention with the water extract of freeze-dried powder of PM (FDPM), cell viability, NO content, and the levels of inflammatory factors such as IL-1β, IL-18, and TNF-α were assessed. Finally, utilizing transcriptomics technology, RT-qPCR, and Western blot methods, the mechanism by which FDPM improves inflammatory injury in rat glomerular mesangial cells was explored and preliminarily validated. RESULTS: FDPM effectively enhances cell viability and inhibits the production of NO and related inflammatory factors. Transcriptomic analysis suggests that FDPM may exert these effects by regulating the TXNIP/NLRP3 signaling pathway. The mRNA and protein expressions of TXNIP, NLRP3, and MCP-1 in the model cells were reversed by FDPM. CONCLUSION: FDPM may improve the micro-inflammatory state of DKD and slow the progression of the disease by regulating the TXNIP/NLRP3 signaling pathway. This study provides a scientific basis for the clinical application of PM DKD treatment.

Por qué esto importa para la hirudoterapia
This study examined the effects of freeze-dried powder from the leech Poecilobdella manillensis (FDPM) on inflammatory injury in LPS-stimulated rat glomerular mesangial cells, an in vitro model for diabetic kidney disease. The findings indicate that FDPM enhances cell viability and reduces inflammatory markers by modulating the TXNIP/NLRP3 signaling pathway. This is highly relevant to the American Society of Hirudotherapy as it explores the anti-inflammatory properties of a specific leech species' extract, expanding the known therapeutic potential of leech-derived substances. A major caveat is that these results are strictly preclinical, based on an in vitro rat cell model, and do not establish clinical efficacy in human patients.
