The video is a time-lapse image sequence corresponding to Figure 6F, showing the interactions of an OVA-specific OT-II CD4 T cell (red) with a CX3CR1-GFP^bright BAM (green) in the proximity of CD11c-YFP^bright DCs (yellow). The OT-II T cell was visualized by the expression of a β-actin-CFP transgene. The image sequence is rendered from a 22 μm z-stack, collected by two-photon microscopy of a cultured precision-cut vibratome section of the lung isolated 6 hr after intranasal OVA challenge. Elapsed time is shown as hh:mm:ss.
