Research overview

This study explores the role of extracellular vesicles (EVs) derived from Clostridioides difficile strain 630 (CD630-EVs), which released spherical EVs during in vitro culture, in modulating pro-inflammatory cytokine production in macrophages. These findings suggest that FliC may play a critical role in intestinal mucosal injury during CDI, highlighting its potential as a therapeutic target for mitigating inflammation in CDI.

Key findings

Clostridioides difficile (CD) is a leading cause of antibiotic-associated diarrhoea in both hospitalized and non-hospitalized patients.

This study explores the role of extracellular vesicles (EVs) derived from Clostridioides difficile strain 630 (CD630-EVs), which released spherical EVs during in vitro culture, in modulating pro-inflammatory cytokine production in macrophages.

Proteomic analysis identified a total of 1064 proteins within CD630-EVs, including four immune-related proteins: FliC, TrxA, TrxA2 and HtpG.

Notably, FliC exhibited the highest expression intensity within immune-related pathways.
