Intercellular tight junctions play a role in various chronic and acute inflammatory diseases, with Larazotide, a zonulin antagonist, potentially serving as a therapeutic strategy. Research has shown the efficacy of Larazotide in different diseases, indicating its potential as a treatment option.
Background: The involvement of intercellular tight junctions and, in particular, the modulation of their competency by the zonulin pathway with a subsequent increase in epithelial and endothelial permeability, has been described in several chronic and acute inflammatory diseases. In this scenario, Larazotide, a zonulin antagonist, could be employed as a viable therapeutic strategy. Objective: The present review aims to describe recent research and current observations about zonulin involvement in several diseases and the use of its inhibitor Larazotide for their treatment. Methods: A systematic search was conducted on PubMed and Google Scholar, resulting in 209 publications obtained with the following search query: Larazotide, Larazotide acetate, AT-1001, FZI/0 and INN-202. After careful examination, some publications were removed from consideration because they were either not in English or were not directly related to Larazotide. Results: The obtained publications were subdivided according to Larazotide's mechanism of action and different diseases: celiac disease, type 1 diabetes, other autoimmune diseases, inflammatory bowel disease, Kawasaki disease, respiratory (infective and/or non-infective) diseases, and other. Conclusion: A substantial role of zonulin in many chronic and acute inflammatory diseases has been demonstrated in both in vivo and in vitro, indicating the possible efficacy of a Larazotide treatment. Moreover, new possible molecular targets for this molecule have also been demonstrated.
