Production of cytokines from PBMCs stimulated with CtTsp and CtHtrA according to participant cohort. PBMCs were isolated from patients belonging to either Infertile (Cpn negative refers to serologically negative for C. pneumoniae IgG MEDAC ELISA), Infertile (Cpn positive or serologically positive for C. pneumoniae IgG MEDAC ELISA, Acute chlamydial infection or TFI cohorts. PBMCs were stimulated in vitro with A) CtTsp and B) CtHtrA, and IL-6 levels detected in supernatants after four days of culture. Unpaired two-tailed t-tests have been performed between cohorts and no significant differences were seen. The cohort numbers were: Infertile Cpn neg n = 7, infertile Cpn pos n = 4, acute infection n = 4, Tubal factor infertility n = 3.
