Cell-adhesion molecules (CAMs) are crucial for synapse formation and brain neural network development. This review explores how CAMs regulate synaptogenesis, stabilization, and plasticity, and their role in neurological disorders.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Cell Biology

Background:

  • Synapses are specialized junctions essential for neural network formation and function.
  • Synaptic connectivity is precisely regulated, implying underlying cellular and molecular mechanisms.
  • Cell-adhesion molecules (CAMs) are key regulators of synaptic structure and plasticity.

Purpose of the Study:

  • To review synaptogenesis stages through the lens of CAMs.
  • To highlight factors regulating CAM function at synapses.
  • To discuss the role of CAM dysfunction in neurological disorders.

Main Methods:

  • Literature review focusing on cell-adhesion molecules in synaptogenesis.
  • Analysis of CAM families including neuroligins, SynCAM, NCAM, L1-CAM, cadherins, protocadherins, and integrins.

  • Discussion of CAM roles in contact initiation, protein recruitment, synapse maturation, and plasticity.

    • Main Results:

    • CAMs are enriched at synaptic junctions and regulate key features of synapse formation.
    • Specific CAM families are involved in distinct stages of synaptogenesis.
    • Dysfunction of synaptic adhesion systems is linked to neurological disorders.

    Conclusions:

    • Cell-adhesion molecules are critical determinants of synaptic specificity, stability, and plasticity.
    • Understanding CAM regulation offers insights into neural circuit development and neurological disease.
    • CAMs represent potential therapeutic targets for neurological disorders.
