In particular, one study shows that Rab3 isoforms regulate presynaptic vesicle trafficking by lowering the Ca²⁺ threshold required for neurotransmitter release, thereby enhancing release probability during synaptic activity yet introducing a delay in vesicle repriming. Such finely tuned modulation of synaptic transmission suggests that any associated regulatory molecule—including a long non‐coding RNA like LINC01070—could feasibly modulate synaptic plasticity through interactions with these vesicle priming or calcium‐sensing pathways."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nA second study underscores the involvement of Rab3b/3c in dendritic cell antigen cross‐presentation.
