title: [Expression of TLR2 and TLR9 genes by epithelial cells of cervical canal mucous membrane in women with inflammatory diseases of small pelvis organs].
abstract: OBJECTIVE
  Determine subpopulation composition of blood lymphocytes and the level of expression of TLR2 and TLR9 by epithelial cells of cervical canal mucous membrane in women of reproductive age with inflammatory disease of small pelvis organs (IDSPO) at exacerbation stage and remission period.
  
  
  METHODS
  Clinical-laboratory and gynecological examination of 105 women was carried out and 3 groups were formed based on the results: patients at IDSPO exacerbation stage; patients at remission stage; clinically healthy women. By using real time PCR, TLR2, TLR9 gene expression levels were determined in epithelial cells of cervical canal mucous membrane in women of all the 3 groups. Subpopulation composition of blood lymphocytes was determined by flow cytofluorimetry by using monoclonal antibodies with CD45+ CD3+ -T-cell, CD45+ CD3+ CD4+ -T-helper, CD45+, CD3+, CD8+ -T-suppressors-cytotoxic killers, CD45+, CD3-, CD16+, CD56+ natural killers, CD45+, CD3-, CD19+ -B-lymphocytes. Immune fluorescence reaction evaluation was carried out in flow cytofluorimeter Cytomics FC 500 (Becton Coulter, USA).
  
  
  RESULTS
  The level of expression of TLR2 gene in the studied groups of patients was established not to differ significantly from parameters in the comparison groups, however it should be noted that this parameter in women with IDSPO at exacerbation stage (causative agents of the infectious process--ureaplasma, staphylococcus, candida) was somewhat higher than in the comparison group. Significantly high level of TLR9 gene expression in cervical canal epithelial cells was detected to correlate with the presence of infectious causative agents. In the group of women with exacerbation of the infectious process the expression of TLR9 was 14.5 times higher compared with the group of women without IDSPO. Among groups of women with IDSPO significant differences in relation to control group in relative and absolute levels of CD3+ T-lymphocytes; CD4+ T-helpers; CD8+ cytotoxic killer T-suppressors, B-lymphocytes compared with the same parameters in clinically healthy women were not detected.
  
  
  CONCLUSIONS
  The increase of TLR9 gene expression level in cervical canal cells of women with IDSPO may serve as an additional diagnostic feature of the presence and degree of severity of the disease.
