CXCL13 enhances B cell margination in the lung. Related to Fig. 5. Intravital lung microscopy was used to investigate the role of exogenously provided CXCL13 on CD19+ B cell (Cd19ZsGreen1; green) margination in the lung capillaries. 12 h after i.t. CXCL13 injection, B cell marginated behavior was assessed. Ly6G+ neutrophils (fluorochrome-conjugated anti-Ly6G antibody; blue) were also labeled. Experiments were repeated three times (n = 3). Playback speed is 12 frames/s, 10 min actual imaging time.
