Cadherins, cell adhesion molecules, are crucial for forming and maintaining synapses in the vertebrate central nervous system. Their specific expression patterns may guide synaptic specificity during development and plasticity.

Area of Science:

  • Neuroscience
  • Cell Biology
  • Developmental Biology

Background:

  • Cadherins are cell-cell adhesion molecules vital for organ morphogenesis.
  • Recent evidence suggests cadherins play a role in synaptogenesis within the vertebrate central nervous system.

Purpose of the Study:

  • To review current evidence on the involvement of cadherins in vertebrate central nervous system synaptogenesis.
  • To explore the role of cadherins in synaptic formation, maintenance, and specificity.

Main Methods:

  • Review of existing literature and electron microscopic studies.
  • Analysis of cadherin expression patterns during neural development, regeneration, and plasticity.

Main Results:

  • N-cadherin is the first identified synaptic cadherin, located at the synaptic cleft.

  • Multiple cadherins are found in synaptic junctions, some in specific synapse subsets.
  • Cadherins' homophilic binding properties support pre- and postsynaptic membrane adhesion.

    • Conclusions:

    • Cadherins are implicated in the formation and maintenance of synapses.
    • Differential cadherin expression in neural circuits may establish synaptic specificity.
    • Cadherins provide a molecular framework for adhesive interactions at the synapse.
