Some aspects of the neuronal cytoskeleton in development

Area of Science:

• Neuroscience
• Cell Biology

Background:

• The neuronal cytoskeleton is crucial for neuronal structure and function.
• Its molecular composition and organization evolve during neuronal development.

Purpose of the Study:

• To review the developmental aspects of the neuronal cytoskeleton.
• To survey the molecular properties of key cytoskeletal proteins.
• To examine the cytoskeleton's role in neuronal cytoarchitecture and function.

Main Methods:

• Literature review of studies on neuronal cytoskeleton development.
• Analysis of molecular properties of cytoskeletal proteins (tubulins, MAPs, neurofilaments, actins, spectrins).
• Examination of the involvement of cytoskeletal elements in neuronal cytoarchitecture.

Main Results:

• Detailed survey of molecular properties of tubulins, microtubule-associated proteins, neurofilament subunits, actins, and brain spectrins.
• Explanation of how microtubules, neurofilaments, microfilaments, and spectrin-based membrane cytoskeleton contribute to neuronal cytoarchitecture.
• Correlation between cytoskeletal composition changes during neuronal differentiation and cell function.

Conclusions:

• The neuronal cytoskeleton's molecular composition and organization are dynamic during development.
• These dynamic changes are integral to establishing neuronal cytoarchitecture and function.
