Figure Lengend Snippet: A. Confocal projection of the head of DAF-28::mCherry; pdaf-7 ::GFP animal, with both ASI neurons visible. DAF-28::mCherry protein (red) localizes exclusively to axons of the ASI and other neurons, and is excluded from dendrites. Green: GFP expressed from a pdaf-7 ::GFP; rol-6 array, used to visualize the ASI. The third dendrite in A is from another animal. A’ shows the axonal area. B. 3D confocal projections of axonal area of the animal in Figure 2B,C , showing both left and right neurons together ( left panel ) and separately; DAF-28::mCherry stereotypically accumulates in synapse-rich areas (ovals in A’ and B). Cell bodies of the ASI, ASJ, ASK, and likely Bag neurons are indicated. C. DAF-28::mCherry is secreted from mammalian cells. Dot blot of DAF-28::mCherry protein in media supernatant from transiently transfected HEK293T cells. The presence of DAF-28::mCherry protein in the media decreases dramatically following 24 hour incubation with 2.5 µg/mL BFA, indicating active vesicle-mediated release. Cell-number equivalents for the amount of media applied in each well are indicated at the bottom. D. Video of a section of the VNC (arrowheads) in the tail area, imaged from the ventral side. DAF-28::mCherry moves in bright puncta. A corresponding video file is Sup. Video 1 . Scale bar for B = 5μm, for D = 20μm.
