Abstract:
Microglial cells are widely distributed in the brain and spinal cord, and usually act as resident immune cells which could provide continuous monitoring roles within the central nervous system. When the cells in the central nervous system are injured, microglial cells are activated and induce a series of biological effects. Recently, several voltage-gated sodium channel subtypes were found to be expressed on the surface of the microglial cells which are able to participate in the regulation of the activation, phagocytosis, secretion of multiple cytokines/chemokines, migration, invasion of microglial cells, and etc. In the present study, the latest progresses on the regulation of voltage-gated sodium channel isoforms on microglial cells were summarized and analyzed. In addition, the mechanism and future research of the relationship between voltage-gated sodium channels and microglial cells were also discussed.
Insights
Voltage-gated sodium channels regulate microglial cell functions, including activation and cytokine secretion. This review summarizes recent advances in understanding these channels
Area of Science:
- Neuroscience
- Immunology
- Cell Biology
Background:
- Microglial cells are the primary immune cells of the central nervous system (CNS), performing surveillance and responding to injury.
- Upon CNS injury, microglial cells become activated, initiating various biological responses.
- Recent discoveries highlight the presence and function of voltage-gated sodium channels (VGSCs) on microglial cells.
Purpose of the Study:
- To review and analyze the latest research on the regulation of microglial cell functions by voltage-gated sodium channel isoforms.
- To discuss the underlying mechanisms and future research directions concerning the interplay between VGSCs and microglial cells.
Main Methods:
- Literature review and analysis of recent scientific publications.
- Synthesis of current knowledge on VGSC expression and function in microglial cells.
- Discussion of experimental findings and theoretical models.
Main Results:
- Several VGSC subtypes are expressed on microglial cells.
- These VGSCs play crucial roles in regulating microglial activation, phagocytosis, cytokine/chemokine secretion, and migration.
- Evidence suggests VGSCs are key modulators of microglial cell behavior in the CNS.
Conclusions:
- Voltage-gated sodium channels are critical regulators of microglial cell activity and function within the central nervous system.
- Further research into VGSC mechanisms in microglial cells holds promise for understanding and treating neurological disorders.
- Targeting VGSCs could offer novel therapeutic strategies for modulating neuroinflammation.

Ligand-Gated Ion Channel Receptor: Gating Mechanism
Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...

Non-gated Ion Channels
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....
The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
