Th17/Th2 cells exclusively found at implantation site of ectopic pregnancy. a Percentage of Th1-, Th2-, Th0- and Th17-cells, and of Th17/Th1 and Th17/Th2 and Th17/Th0 among the CD4+ T cell clones derived from the implantation site of embryo (N = 133) and those distant from the implantation site in the same fallopian tube (N = 62) of 3 women suffering from ectopic pregnancy. Data are represented as mean ± SEM. b Levels of IL-4, IL-17A, IL-17F and IL-22 produced by the CD4+ T cell clones at the implantation site (N = 133) and distant from the implantation site (N = 62). Data are represented as mean ± SEM. c mRNA levels of IL-4, GATA-3, IL-17A, ROR-C and IFN-γ in the biopsies taken at embryo implantation site and distant from the implantation site in the fallopian tube of three women suffering from ectopic pregnancy. For a, c the statistical analysis was performed with Chi-square test. For b the statistical analysis was performed with Wilcoxon test
