ITLN1 exacerbates Crohn's colitis by driving ZBP1-dependent PANoptosis in intestinal epithelial cells through antagonizing TRIM8-mediated CAPN2 ubiquitination.

ABSTRACT: Background: This study aimed to investigate the mechanisms by which PANoptosis of intestinal epithelial cells (IECs) promotes Crohn's disease (CD) progression. Methods: Single-cell RNA sequencing (scRNA-seq) was performed on inflamed and uninflamed colon tissues from patients with CD. The biological functions of intelectin-1 (ITLN1) in inflammation and PANoptosis were verified through in vitro experiments. The molecular mechanisms underlying its biological functions were examined using co-immunoprecipitation (Co-IP) combined with mass spectrometry (MS) and RNA-seq and further validated with rescue experiments. Additionally, the in vivo function of ITLN1 regulation on inflammation, PANoptosis, and the intestinal mucosal barrier was explored in interleukin-10 knoc
