TCR and CD40L microclusters are linked in synaptic ectosomes (extracellular vesicles) and released in the immunological synapse by helper T cells and induce dendritic cell maturation and cytokine production.
Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.
Structural and functional striatal synaptic plasticity abnormalities occur early in a sensitive developmental period, representing a potential unique endophenotypic traits that increase the risk of manifesting clinical symptoms in DYT1 mutation carriers.
A model for synchronous neurotransmitter release suggests that when not in the presence of calcium ions, Synaptotagmin proteins form ring-like structures between the vesicle and plasma membrane that prevent spontaneous fusion.
Clarinet, a novel C. elegans active zone protein with homology to vertebrate Piccolo and Rim, uses its different isoforms for diverse functions, including synaptic vesicle clustering, vesicle release and synaptogenesis.
Synaptic defects previously attributed to loss of kinesin function are found to be mediated by the Wnd/DLK axonal injury signaling pathway, which restrains the total levels of presynaptic proteins in response to their accumulation.
