HtpG-High-Expressing Escherichia coli Promotes Fibrosis in Chronic Pancreatitis.

HtpG-high-expressing Escherichia coli (HHEC) is enriched in chronic pancreatitis patients and exacerbates disease via a macrophage-mediated pathway.

• Why it matters: Understanding the microbial factors that promote CP can reveal new therapeutic targets, as gut dysbiosis is associated with disease progression but its causal role remains unclear.
• What they did: Multi-omics analyses identified HHEC enrichment in CP, and functional studies using in vitro and in vivo models showed that HHEC promotes fibrosis through upregulating PRMT5 in pancreatic macrophages.
• The result: Inhibiting PRMT5 or colonizing with beneficial microbes like Akkermansia muciniphila reduced fibrosis and CP severity, suggesting microbiota-targeted therapies may benefit CP management.
