For instance, one study demonstrated that the combined deficiency of Pglyrp3 and Nod2 in mice leads to exacerbated colitis characterized by increased epithelial apoptosis, altered gut microbiota, and elevated ATP levels. These findings emphasize the importance of tight regulation in maintaining intestinal homeostasis – a context in which regulatory RNAs such as FANK1‑AS1 might participate by fine‐tuning gene expression and inflammatory signaling pathways."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAnother investigation focused on the ocular surface revealed that other members of the peptidoglycan recognition protein family are essential for antibacterial defense in Pseudomonas aeruginosa keratitis.
