Matcham AC, Toma K, Tsai NY, Sze CJ, Lin PY, Stewart IF, Duan X (2024) Cadherin-13 Maintains Retinotectal Synapses via Transneuronal Interactions. J Neurosci 44(5):e1310232023. doi: 10.1523/JNEUROSCI.1310-23.2023 PMID: 38123991
Objective: To explore the role of Type II cadherins, particularly Cdh13, in the formation of specific retinotectal synapses.
Summary: Cdh13 is highly expressed in wide-field neurons of the superficial superior colliculus (sSC), and its removal from presynaptic retinal ganglion cells (RGCs) leads to a significant reduction in dendritic spines on postsynaptic wide-field neurons. Unlike αRGCs and On–Off Direction-Selective Ganglion Cells (ooDSGCs), Cdh13-expressing RGCs utilize distinct mechanisms to establish precise retinotectal connections.
Usage: Immunohistochemistry (1:500).
