(A,E,I) Left panels: Astrocytes expressing EAAT1-GFP (A), Cx43-GFP (E) or treated with a probe that labels late endosomes and lysosomes (I). Red boxes indicate regions used to analyze particle dynamics. Right panels: Original and color-coded kymographs showing trajectories for the indicated cargos. Red lines represent retrograde-moving cargos, green lines anterograde-moving cargos, and blue lines non-motile cargos. (B,F,J) Percentage of stationary and motile particles. (C,G,K) Quantification of anterograde and retrograde velocity and (D,H,L) run length. Data represents mean ± SEM. Please click here to view a larger version of this figure.
