AhR–RBX1/HSF1 Signaling in Acute Pancreatitis
2026-09-21
A 2025 study identifies an aryl hydrocarbon receptor (AhR)–RBX1–HSF1 regulatory axis that links pancreatic acinar-cell stress, tight-junction integrity, and resident macrophage polarization during acute pancreatitis. Its combination of mouse modeling, primary-cell experiments, conditioned-medium analysis, and ubiquitination-focused validation provides a mechanistic framework for studying barrier injury, while also highlighting important questions about HSF1 directionality and triptolide target specificity.

25-Hydroxycholesterol Reprograms Immunosuppressive TAMs
2026-09-21
Xiao et al. show that tumor-associated macrophages accumulate 25-hydroxycholesterol through CH25H, activating a lysosomal GPR155–mTORC1–AMPKα pathway that reinforces STAT6-dependent ARG1 expression. CH25H disruption reprograms the tumor immune microenvironment, increases T-cell activity, and improves responses to anti-PD-1 therapy.
