Video 1. FRC-specific ATX ablation reduced the velocity of T cells in LNs.
Intravital two-photon microscopy was used to analyze the intranodal migration of eGFP-expressing CD4+ T cells (green) 15 hr after the cells were injected into Enpp2fl/fl (left) or Ccl19-Cre Enpp2fl/fl mice (right). Data shown are representative of three independent experiments. Bars, 50 μm.
