This brush border enzyme (ecto-enzyme) plays an important role in the maintenance of intestinal microbial homeostasis and intestinal barrier function through its ability to dephosphorylate lipopolysaccharide (LPS). This review addresses how IALP and intestinal barrier dysfunction may be implicated in the pathophysiology of specific diseases such as inflammatory bowel disease, necrotizing enterocolitis, and metabolic syndrome. The use of IALP as a possible biomarker to assess intestinal barrier function and strategies to modulate IALP activity are also discussed.1480572enginflammatory bowel diseaseintestinal alkaline phosphataseintestinal barrier functionlow-grade chronic inflammationmetabolic dysfunctionnecrotizing enterocolitisobesityMicrobiologyMicrobiology (medical)VirologySDG 3 - Good Health and Well-beingreview10.3390/microorganisms10040746https://www.scopus.com/pages/publications/85127426722
