Schematic image of the experimental set-up of transmigration experiments. At first HIBCPP cells were infected with E-30 MOI (0.7) T = 0 h. At T = 24 h post infection T cells were labeled with cell tracker green and added to the upper compartment of the well. CXCL12 was added to the bottom of the well in some conditions. At the end of the 4 h of migration experiment the filters were removed and the T cells present on the bottom part of the well were counted under the microscope
