Assay of sIL-2R and TNF-α in experimental allergic encephalomyelitis

摘要

Objective: To investigate the change and effect of sIL-2R and TNF-α in the immunopathogenesis of experimental allergic encephalomyelitis(EAE). Methods: The EAE model was induced in guinea pigs. And the EAE animals were killed on the 8th, 15th and 22nd day after the MBP+CFA challenge. ConA-treated guinea pig spleen cells were cultured and supernatants were collected. The level of sIL-2R in supernatant was detected by ELISA, and the level of TNF-α in EAE was examined by biologic assay. Results: The EAE animals showed higher levels of sIL-2R and TNF-α than those of the normal control group. Conclusion: sIL-2R and TNF-α play an important role in the immunopathogenesis of EAE. This experiment offered thoretical evidence for further study of multiple sclerosis(MS) on pathogenesis and gave the clues for clinical use of immunospecific agents on MS.%目的:研究sIL-2R和TNF-α在实验性变态反应性脑脊髓炎(EAE)免疫发病机制中的变化与作用.方法:应用豚鼠诱导EAE动物模型.在MBP+CFA免疫豚鼠的第8、15、22天处死动物,取脾细胞,加入ConA诱生培养,收集上清液,采用ELISA方法测定sIL-2R水平,采用生物活性测定法检测TNF-α水平.结果:EAE组的sIL-2R与TNF-α水平明显高于正常对照组.结论:sIL-2R及TNF-α在EAE免疫发病机制中具有重要作用.
