MyD88-GFP dynamics in WT, IRAK4 KO, and IRAK1 KO EL4 cells (related to Fig. 6). This video shows MyD88-GFP in WT (left), IRAK1 KO (middle), and IRAK4 KO (right) EL4 cells landing on an IL1β-functionalized supported lipid membranes. White box in each panel indicates example cells shown in Fig. 6 A. Scale bar, 5 µm.
