Summary
Calcium signaling disruption is key in blast-related traumatic brain injury (bTBI). Targeting calcium channels offers potential neuroprotective strategies for military personnel experiencing bTBI.
Area of Science:
- Neuroscience
- Molecular Biology
- Trauma Research
Background:
- Repeat low-level blast exposure is a growing concern for military populations.
- Blast-related traumatic brain injury (bTBI) has poorly understood molecular mechanisms.
- Loss of calcium homeostasis is a suspected mediator of early neuronal dysfunction after blast injury.
Purpose of the Study:
- To review the role of calcium signaling in bTBI.
- To examine calcium channels as mediators and modulators of injury.
- To explore therapeutic strategies targeting calcium homeostasis.
Main Methods:
- Review of 13 peer-reviewed articles (2000-2024) from PubMed, Scopus, EBSCO.
- Search terms: "blast traumatic brain injury", "calcium channels", "calcium".
- Inclusion of studies on intracellular calcium dynamics post-bTBI; exclusion of extracellular calcium and biomarker studies.
Main Results:
- Dysregulated calcium signaling correlates with cellular dysfunction (membrane abnormalities, cytoskeletal destabilization, mitochondrial dysfunction).
- Specific neuronal and astrocyte vulnerabilities identified, suggesting targeted interventions.
- Therapeutic strategies include pharmacological inhibitors, membrane stabilizers, and secondary injury modulators.
Conclusions:
- Calcium signaling plays a critical role in bTBI pathophysiology.
- Standardized research approaches are needed to clarify calcium channel dynamics in bTBI.
- Targeting calcium homeostasis may lead to effective neuroprotective interventions for bTBI recovery.

2.1K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

7.9K
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
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...
