title: [Expression of SOCS-1, 3 induced by Chlamydia trachomatis-infected Hela229].
abstract: OBJECTIVE
  To explore the relationship between SOCS, immune suppression and chlamydial persistence of Chlamydia trachomatis-infected cells.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
