Objective: To explore the role of NLRP3 in mucus hypersecretion in asthmatic patients. Methods: From January 2020 to June 2022, 90 patients with asthma and 60 healthy patients under the Department of Pulmonary and Critical Care Medicine of the First Affiliated Hospital of Xi’an Medical University were selected. Immunohistochemistry and enzyme-linked immunosorbent assay were performed. NLRP3 inflammasome and mucins MUC5AC and MUC5B levels in lung tissue and sputum were detected. Results: Compared to the healthy control group, the asthma group had significantly higher sputum MUC5A (20.12 ± 5 .07 versus 36.21 ± 6.13) and NLRP3 (72.31 ± 15.13 versus 119.21 ± 31.21) levels (P < 0.05) but lower MUC5B levels (1.35 ± 0.12 versus 0.53 ± 0.11, P < 0.05). Immunohistochemistry showed that NLRP3, MUC5AC, and MUC5B expressions were consistent with the sputum results. Conclusion: NLRP3 and MUC5AC levels are significantly increased in asthmatic patients, whereas MUC5B levels are reduced in these patients. They can be used as targets for the diagnosis and treatment of asthma.
