To explore the relationship between SOCS, immune suppression and chlamydial persistence of Chlamydia trachomatis-infected cells.
After being infected with Chlamydia trachomatis, RT-PCR was used to examine the expression of SOCS-1, 3 mRNA and Western blotting to examine the expression of SOCS-1,3 protein in Hela229 cells. Immunofluorescence was used to examine the effect of SOCS obstruction on the multiplication of Chlamydia trachomatis.
Chlamydia trachomatis-infected Hela229 cells can induce the expression of SOCS-1,3 both on mRNA level and on protein level. The multiplicity of Chlamydia trchomatis can be suppressed after the expression of SOCS-1,3 was obstructed.
Chlamydia trachomatis-infected Hela229 cells can induce the expression of SOCS-1,3, which is one of the mechanisms that Chlamydia trachomatis can suppress host immune and result in persistence.
探讨细胞因子信号转导抑制因子(SOCS)、免疫抑制与沙眼衣原体感染细胞中衣原体持续存在之间的关系。
用沙眼衣原体感染Hela229细胞后,采用逆转录-聚合酶链反应(RT-PCR)检测细胞中细胞因子信号转导抑制因子1(SOCS-1)、3 mRNA的表达,蛋白质免疫印迹法检测SOCS-1、3蛋白的表达。采用免疫荧光法检测SOCS阻断对沙眼衣原体增殖的影响。
沙眼衣原体感染的Hela229细胞可在mRNA水平和蛋白水平诱导SOCS-1、3的表达。阻断SOCS-1、3的表达后,沙眼衣原体的增殖能力受到抑制。
沙眼衣原体感染的Hela229细胞可诱导SOCS-1、3的表达,这是沙眼衣原体抑制宿主免疫并导致持续感染的机制之一。
