Here, we describe the first application of a novel viral tracer, based on vesicular stomatitis virus (VSV), which directs retrograde transsynaptic viral spread between defined cell types.
Because the twitching contractions appeared to be coordinated or synchronized in the whole heart, they could be caused by interference between the caudal cardiac pacemaker and neural activity from the anterior aorta directing retrograde contractions.
COPI directs retrograde sorting of membrane proteins from the Golgi to the ER and a widely accepted model is that this retrograde recycling is initiated at the ERGIC and continues during transit of cargo to the Golgi.
The huα-syn in the amygdala could be the result of direct retrograde transport from the accessory OB along axons originating in the amygdala [ 53].
It has also been reported that Exo2 does not affect the integrity of the TGN (trans-Golgi network), or the direct retrograde trafficking of the glycolipid-binding cholera toxin from the TGN to the ER lumen.
Another direction suggests mechanical competition between sets of anterograde and retrograde directed motors (Guerin et al., 2010; Muller et al., 2008).
Therefore, it is possible that Scyl1 uses its 58K binding/golgin network association to position itself to regulate KDEL receptor trafficking events more directly, possibly through the modulation of KDEL receptor phosphorylation, a state that is known to be critical for KDEL receptor inclusion in COPI retrograde directed vesicles [35].
In this study, we seek to gain insight into how small anterograde (and retrograde) directed cargoes traverse stacked Golgi.
We screened for proteins that may serve as a Ctnnb1-directed retrograde factor and identified Slit2.
Recent loss and gain of function studies strongly suggest involvement of the DCLK gene in neurogenesis, neuronal migration, vesicle transport, microtubule-directed retrograde transport, neurotransmission and apoptosis [ 28- 30, 44- 46].
