Pharmacological inhibition of N-Acylethanolamine acid amidase (NAAA) mitigates intestinal fibrosis through modulation of macrophage activity

Intestinal fibrosis, a frequent complication of inflammatory bowel disease, is characterized by stricture formation with no pharmacological treatment to date. N-acylethanolamine acid amidase (NAAA) is responsible of acylethanolamides (AEs, e.g., palmitoylethanolamide and oleoylethanolamide) hydrolysis. Here, we investigated NAAA and AEs signalling in gut fibrosis.
