Abstract:
:The delivery of proteins to the presynaptic terminals of guinea pig retinal ganglion cells by two of the major components of axonal transport, and the subsequent persistence and turnover of those proteins were examined in this study. Ganglion cell proteins were radiolabeled by intravitreal injection of radiolabeled amino acids and radioactive axonally transported proteins were analyzed in synaptosomes prepared from the superior colliculi. This procedure allowed examination of presynaptic components of ganglion cell synapses without having to compensate for postsynaptic or other unidentified contaminants. Each of the two major axonal transport components supplies a large number of proteins to the presynaptic terminal, in relative quantities similar although not identical to those seen in the axon. Proteins conveyed by the fast component of axonal transport reached the terminals by 3 h after intraocular injection, peaked by 24 h, and were largely undetectable by 15 days. Slow component b proteins reached the terminals by 12 days, peaked around 21 days, and persisted up to 63 days in the terminals. Proteins in both components demonstrated differential turnover relative to cotransported proteins once they reached the terminals. Differential turnover may account for change in relative concentration of a particular protein required to meet new functional demands on that protein once it enters the terminal.
