Summary
Neuronal migration is crucial for brain development, with disruptions linked to disorders like autism. This review examines how microfilaments and microtubules regulate excitatory neuron migration and the role of autism risk genes.
Area of Science:
- Neuroscience
- Developmental Biology
- Genetics
Background:
- The mammalian neocortex has six distinct neuronal layers essential for brain function.
- Neuronal migration, particularly radial migration of excitatory neurons, is critical for forming functional neural circuits.
- Aberrant neuronal migration is associated with neuropsychiatric disorders, including autism spectrum disorder (ASD), schizophrenia, and epilepsy.
Purpose of the Study:
- To review the regulation of microfilaments (actin filaments) and microtubules during excitatory neuron radial migration.
- To highlight the role of cytoskeleton-associated genes in neuronal morphology and migration.
- To discuss the involvement of ASD-associated risk genes in radial migration.
Main Methods:
- Literature review focusing on molecular and genetic regulation of neuronal migration.
- Analysis of signaling pathways and cytoskeletal dynamics (microfilaments and microtubules).
- Examination of gene expression and function related to neuronal migration and ASD.
Main Results:
- Cytoskeletal components, specifically actin filaments and microtubules, are key regulators of excitatory neuron radial migration.
- Cytoskeleton-associated genes significantly influence neuronal shape and migratory capacity.
- Several genes linked to ASD risk play a role in the radial migration process.
Conclusions:
- Proper regulation of the cytoskeleton is vital for normal excitatory neuron migration during neocortex development.
- Understanding the genetic underpinnings of radial migration offers insights into the etiology of neurodevelopmental disorders like ASD.
- Further research into ASD-associated genes and their impact on neuronal migration may reveal therapeutic targets.

01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
01:21Cell Polarization by Rho Proteins
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...
01:18Role of Myosin in Cell Migration
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...

01:09Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
01:24Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
01:32Assembly of Complex Microtubule Structures
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.
