The infected cultures were incubated at 37°C and 5% CO2 for intended durations. For immunofluorescence, cells were grown on coverslips.

The cell pellets for PCR/reinfection as well as supernatants for cytokine analysis were stored at −80°C. Mock infected controls were prepared for every set of experiment to assess the contribution of host cell debris. Control samples were routinely checked for the presence of chlamydia antigens in the donor samples by immunofluorescence microscopy.
Immunofluorescence microscopy The infected monocytes and DCs after intended incubation were fixed in 2% para-formaldehyde for 10 min and washed 3 times in PBS. Cells were permeabilized with 0.5% TritonX-100 for 3 minutes. Following fixation, the cells were blocked with PBS containing 1% BSA and 1% FCS. Genus-specific fluorescein isothiocyanate (FITC)-labelled monoclonal antibody (Pathfinder Chlamydia Confirmation System; Bio-Rad, Redmond, WA) was used to stain the chlamydial inclusions, while the monocytes and DCs were counterstained with Evan’s Blue at room temperature for 45 min. The samples were then washed once with PBS and then washed twice with PBS/DAPI (1:2500) to stain the cell nuclei. Images were
captured in Vistusertib cost 10 random fields with a fluorescence microscope (Leica DMLB, Germany) with standard filters at 63X magnification. ImageJ was used to count the number of inclusions/cells in replicate samples. Data from 3 independent experiments were combined to calculate the mean and standard deviation. Analysis of the infectivity of C. trachomatis in monocytes/DCs Cells
harvested at different time points were lysed in an ultrasonic sonicator bath (Jürgen’s Hannover, Germany). Cell lysates were used to infect HeLa cells seeded on coverslips and cultured in MEM media containing 1 μg/ml cycloheximide at 37°C in 5% CO2 for the intended duration. At the end of the infection period, cells were fixed for 10 min in absolute methanol, air-dried, and stained using FITC-labelled monoclonal antibody (Pathfinder Chlamydia Confirmation System; Bio-Rad, Redmond, WA) and counterstained with Evan’s blue. Images were captured in 10 random fields with a fluorescence microscope (Leica DMLB, Germany) with Protirelin standard filters at 40X magnification. The inclusions were counted as described under section Immunofluorescence microscopy. Data from 3 independent experiments were combined to calculate the mean and standard deviation. Gene expression analysis by real-time PCR For the analysis of chlamydial gene expression, infected cells were harvested at different time points and real-time PCR was performed targeting the 16S rRNA gene as described previously [34]. To analyse chlamydial developmental phase, expression of genes euo, ompA and omcB were performed.
