Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.
An integrated approach for studying laminar organization in the developing mouse retina identifies two families of extracellular recognition proteins that mediate neuronal subtype-specific recognition.
Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.
Crystal structures of synaptic recognition molecules Sidekick-1 and -2 reveal a single homodimer interaction mode responsible for both cell-cell recognition and cis-clustering, suggesting that competition between cis and trans interactions may be critical to specificity.
Clinical, clinicopathological and image data from Malawian children shows that sequestration in P. falciparum cerebral malaria is visible clinically in the eye as orange retinal vessels and is strongly associated with death.
A quantitative analysis of the connectivity between photoreceptors and bipolar cells in the mouse retina based on electron microscopy data yields exceptions from established rules of outer retinal connectivity.
While photoreceptor and bipolar cells exhibit very similar cis-regulatory grammars, subtle differences in homeodomain motif enrichment represent a key distinction driving the divergence in their transcriptomes.
