Abstract

Acute pancreatitis (AP) is a severe inflammatory condition characterized by the activation of pancreatic enzymes within acinar cells, leading to tissue damage and inflammation. Interleukin (IL)‑22 is a potential therapeutic agent for AP owing to its anti‑inflammatory properties and ability to promote tissue repair. The present study evaluated the differentially expressed proteins in arginine‑induced pancreatic acinar cell injury following treatment with IL‑22, and the possible mechanisms involved in IL‑22‑mediated alleviation of AP. AR42J cells were stimulated using L‑arginine to establish an acinar cell injury model in vitro and the damaged cells were subsequently treated with IL‑22. The characteristics of the model and the potential therapeutic effects of IL‑22 were examined by CCK‑8 assay, flow cytometry, TUNEL assay, transmission electron microscopy and ELISA. Differentially expressed proteins in cells induced by arginine and treated with IL‑22 were assessed using liquid chromatography‑mass spectrometry. The identified proteins were further subjected to Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis to elucidate their functional roles. The present study demonstrated that arginine‑stimulated cells showed significant pathological changes resembling those in AP, which were alleviated after IL‑22 treatment. Proteomic analysis then demonstrated that in IL‑22‑treated cells, proteins related to the formation and fusion of autophagosomes with lysosomes were significantly downregulated, whereas endocytosis related proteins were enriched in the upregulated proteins. After IL‑22 treatment, western blotting demonstrated reduced expression of autophagy‑associated proteins. In conclusion, by inhibiting the formation and fusion of autophagosomes with lysosomes, IL‑22 may have mitigated premature trypsinogen activation, subsequently minimizing acinar cell injury induced by L‑arginine. This was accompanied by concurrent upregulation of endocytosis, which serves a pivotal role in sustaining regular cellular material transport and signal propagation. This research underscored the potential of IL‑22 in mitigating arginine‑induced AR42J injury, which could be valuable in refining treatment strategies for AP.
