However, the expression of CXCL chemokines governing the infiltration of neutrophils in UC has not been well elucidated.Materials and methods: In this experimental study, the UC model was induced in Wistar rats by administration of 2 mL 4% acetic acid into the large colon through the rectum. Animals were anesthetized after 48 hrs; their colon tissue samples were isolated for macroscopic and histopathological examinations. The expression of CXCL family was assessed by reverse transcription polymerase chain reaction (qRT-PCR) technique.Results: Heavy infiltration of neutrophils, coagulation necrosis, and ulcers were observed in H&E staining, which pathologically proved the UC model. qRT-PCR results showed that ELR+, CXC chemokines such as CXCL6 and CXCL3 had the highest expression in the UC group, which was 49 and 28 times higher than that of the control group, respectively. In addition, other chemokines of this group including CXCL1, CXCL2, and CXCL7 had a significant increase compared to the control group (P≤0.05). However, ELR−, CXC chemokines such as CXCL4, CXCL13, and CXCL16 showed a smaller upregulation, while CXCL14 chemokine showed a significant decrease compared to the control group (P≤0.05). However, the expression of CXCL9-12 and CXCL17 did not change.Conclusion: The results showed that the ELR+, CXC chemokines, especially CXCL6 and CXCL3, many involved in the pathogenesis of UC; therefore, CXCL6 and CXCL3 chemokines can be used as therapeutic targets for UC, although more studies using human samples are required.Keywords: ELR+, CXC chemokines, chemokine, CXCLs, ulcerative colitisBoshagh MAForoutan PMoloudi MRFakhari SMalakouti PNikkhoo BJalili ADove Medical PressarticleELR+ CXC chemokinesChemokineCXCLsUlcerative Colitis.PathologyRB1-214Therapeutics.
