日本血吸蟲成蟲可溶性蛋白和重組半胱氨酸蛋白酶抑制蛋白抑制小鼠結腸炎的研究(英文)
發(fā)布時間:2021-06-12 22:10
目的探討日本血吸蟲可溶性成蟲蛋白(SjSWP)和重組半胱氨酸蛋白酶抑制蛋白(rSjcystatin)對模擬炎癥性腸病的小鼠結腸炎的作用。方法 24只BALB/c雌鼠分為健康對照組、磷酸鹽緩沖液組(PBS組)、rSjcystatin治療組(rSjcystatin組)、 Sj SWP治療組(SjSWP組)。PBS、 rSjcystatin、 SjSWP組用0.1 ml 5%2,4,6-三硝基苯磺酸(TNBS)灌腸誘導結腸炎,灌腸后6、 24 h分別腹腔注射100μl PBS、 50μg r Sjcystatin、 50μg SjSWP;健康對照組在相應時間點用等量的PBS灌腸及腹腔注射。TNBS灌腸72 h后無痛處死各組小鼠,檢測宏觀評分、結腸長度、髓過氧化物酶活性和顯微鏡下微觀評分來評估炎癥參數(shù)和病理改變。流式細胞儀檢測小鼠脾臟中Th1和Th2及T調(diào)節(jié)細胞(Tregs)的比例。ELISA檢測小鼠結腸組織勻漿上清中γ干擾素(IFN-γ)、白細胞介素-4 (IL-4)、 IL-13、 IL-10等炎性細胞因子的水平。多組計量資料分析采用單因素方差分析,多組均數(shù)間的兩兩比較用Student-N...
