Figure 5.
TeNT HC retrograde carriers partially colocalize with NGF-labeled compartments. MNs were incubated with TeNT HC Alexa488 and Texas red NGF for 30 min at 37°C. Cells were then washed and imaged by time-lapse confocal microscopy. The cell body is located out of view to the right. (a) TeNT HC Alexa488 and (b) Texas red NGF colocalize in retrograde carriers (arrowhead, asterisk, arrow) (see Video 3, available at http://www.jcb.org/cgi/content/full/200106142/DC1). (c) Merged image of a and b. (d) Corresponding DIC image. TeNT HC (e) and NGF (f) are found only in round vesicles (arrowhead), whereas tubules appear to be labeled only by TeNT HC (*). (g) Merged image of e and f. (h–j) Many TeNT HC carriers colocalize with p75NTR (arrowheads). MNs were incubated with TeNT HC Alexa488 (h), fixed, immunostained for p75NTR (i), and imaged by confocal microscopy. (j) Merged image of h and i. Bars, 5 μm.
