Genetically determined variability of immune response may underline inter-individual differences in the susceptibility to periprosthetic joint infection (PJI), which via bacterial colonisation complicates total joint arthroplasties (TJA). This project aims at investigating single nucleotide polymorphisms (SNP) within key molecules of Th17 immune response in PJI. The SNPs in genes coding for IL-4, 17, 35, 12B, 23R, IFN gamma, CXCL1 a 5 will be determined by TaqMan or PCR-SSP assays. The mRNA levels of selected cytokines with the most relevant SNPs concerning PJI will be measured by quantitative RT-PCR in synovial cells. Comparison will be made between distributions of SNP variants in group of patients with PJI (n=80-100) and patients without PJI (n=120-150), moreover the effect of SNPs carriage on corresponding cytokine mRNA levels will be assessed. By identification of particular gene variants contributing to PJI, this project will extend our knowledge on pathological immune mechanisms of PJI and suggest genetic markers for testing of PJI risk at presurgical stage.
