目的:探讨皮下注射白细胞介素2后生殖器疱疹患者T细胞中磷酸化信号转导和转录激活因子5( Signal transducer and activator of transcription 5,STAT5)的表达和STAT5的DNA结合活性。方法共6例复发性生殖器疱疹患者进入本研究,白细胞介素2皮下注射28 d后,采血,分离T细胞,采用蛋白免疫印迹技术和凝胶滞留法( Electrophoretic mobility shift assay , EMSA)检测了外周血T细胞中磷酸化STAT5的表达和STAT5的DNA结合活性,并对其进行了定量分析。结果经白细胞介素2治疗后第28天,可见生殖器疱疹患者外周血T细胞核蛋白中磷酸化STAT5的表达是未经治疗时的1.8~2.7倍;治疗后STAT5的DNA结合活性增高2.3~3.4倍,治疗后与治疗前之间的差异有统计学意义( t =10.6, P <0.01)。结论白细胞介素2皮下注射后生殖器疱疹患者T细胞中磷酸化STAT5的表达和STAT5的DNA结合活性显著增高,提示STAT5是白细胞介素2治疗的重要信号介质,并且STAT5的激活可提示患者是否对白细胞介素2治疗有反应。为临床应用白细胞介素2治疗生殖器疱疹提供了临床理论依据。
目的:探討皮下註射白細胞介素2後生殖器皰疹患者T細胞中燐痠化信號轉導和轉錄激活因子5( Signal transducer and activator of transcription 5,STAT5)的錶達和STAT5的DNA結閤活性。方法共6例複髮性生殖器皰疹患者進入本研究,白細胞介素2皮下註射28 d後,採血,分離T細胞,採用蛋白免疫印跡技術和凝膠滯留法( Electrophoretic mobility shift assay , EMSA)檢測瞭外週血T細胞中燐痠化STAT5的錶達和STAT5的DNA結閤活性,併對其進行瞭定量分析。結果經白細胞介素2治療後第28天,可見生殖器皰疹患者外週血T細胞覈蛋白中燐痠化STAT5的錶達是未經治療時的1.8~2.7倍;治療後STAT5的DNA結閤活性增高2.3~3.4倍,治療後與治療前之間的差異有統計學意義( t =10.6, P <0.01)。結論白細胞介素2皮下註射後生殖器皰疹患者T細胞中燐痠化STAT5的錶達和STAT5的DNA結閤活性顯著增高,提示STAT5是白細胞介素2治療的重要信號介質,併且STAT5的激活可提示患者是否對白細胞介素2治療有反應。為臨床應用白細胞介素2治療生殖器皰疹提供瞭臨床理論依據。

Objective To observe the expression of phosphorylation of signal transducer and activa -tor of transcription 5 (STAT5) protein and the DNA-binding activity of STAT5 after interleukin 2 therapy for genital herpes .Methods Six patients with recurrent genital herpes were included in this study .CD4 +T cells from patients who underwent interleukin 2 therapy were analyzed for changes in STAT 5 signaling.None had been treated with corticosteroid and immunosuppressive agents .Phosphorylation of STAT 5 was detected in the T cells using Western blot analysis .Electrophoretic mobility shift assay ( EMSA) was carried out to detect the DNA-biding activity of STAT5.Results The expressions of phosphorylated STAT 5 in T cells de-rived from patients with genital herpes 28 days after interleukin treatment were 1.8~2.7 fold to that of be-fore the treatment was given .STAT5 DNA-binding activity in T cells derived form patients with genital her-pes who had received the treatment was 2.3~3.4 fold increased compared to that of before the initiating of interleukin 2 treatment.The differences between the before and after interleukin 2 treatment were statistical-ly significant( t =10.6, P <0.05).Conclusion This study indicates that STAT5 may be an important signaling mediator of interleukin 2 therapies , and that STAT5 activation may predict response to this treat-ment .
