RSV感染裸鼠模型建立及病理特征分析
[Abstract]:Objective to establish a nude mouse model of respiratory syncytial virus (respiratory syncytial virus,RSV) infection and observe the replication of RSV, infiltration of airway inflammatory cells, lung injury and airway hyperresponsiveness (AHR), without T cell interference. It lays a foundation for further study of the pathogenicity of innate immunity in RSV. Methods female T-cell deficient nude mice (Balb/c background) and normal Balb/c mice were divided into control group and RSV group at 6 weeks. The supernatant of cell culture or RSV A2 virus solution were inoculated by nasal drip, and the titer of virus was detected by plaque test. Bronchoalveolar lavage fluid (BALF) was perfused with inflammatory cell count and classified count; some mice took left lung and HE staining was used for histological grading; lung function was measured by whole body sketching technique; cytokine was detected by ELISA method. Results the clearance of virus in nude mice was delayed than that in Balb/c mice, and RSV caused obvious inflammatory cell infiltration in both nude mice and Balb/c mice, and the pathological injury of lung tissue and AHR, could be sustained for at least 60 days. After RSV infection in nude mice and Balb/c mice, cytokines showed a biphasic change. In acute phase, interferon was mainly increased, and in chronic phase, Th2 cytokines were mainly increased. Conclusion innate immunity is independent of T cells and independent mediates acute and chronic airway inflammation associated with RSV and AHR, suggests that the role of innate immunity should be fully considered in the development of RSV vaccine or drug.
