CXCR3A and CXCR3B induce distinct βarr2 trafficking patterns. Confocal microscopy of HEK 293 cells transiently transfected with unlabeled CXCR3A or CXCR3B and βarr2-GFP pre-CXCL11 (left panels) and post-CXCL11 (three right panels) treatment (100 nM). Three different cells are shown post-treatment of each splice variant.
