Ischemic Stroke ll: Pathophysiology

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Voltage-gated Ion Channels

Voltage-gated Ion Channels

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 types of...

Ion Channels

Ion Channels

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.
Ion channels are specialized integral membrane proteins on the plasma membrane that allow specific...

Stroke: Introduction and Types

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...

Ligand-gated Ion Channels

Ligand-gated Ion Channels

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
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 include the...

Background:

Vascular remodeling of cerebral arterioles, involving vascular smooth muscle cells (VSMCs), is a primary cause of stroke.
Chloride (Cl(-)) channels are increasingly recognized for their significant role in vascular remodeling and stroke pathogenesis.

Purpose of the Study:

To review the functional roles of Cl(-) channels in the development of stroke.
To provide a perspective on future research directions and therapeutic potential of Cl(-) channels for stroke.

Main Methods:

Review of existing literature on Cl(-) channels in VSMCs and their relation to stroke.
Analysis of the roles of specific Cl(-) channels, including TMEM16A (Ano1), CLC-3, and CFTR, in vascular function.
Examination of the involvement of GABA receptor-mediated Cl(-) currents in ischemic neuron death.

Main Results:

TMEM16A (Ano1) activation leads to vasoconstriction and inhibits VSMC proliferation.
Volume-regulated Cl(-) channels (VRCCs) activation promotes VSMC proliferation and inhibits apoptosis.
Cystic fibrosis transmembrane conductance regulator (CFTR) activation may prevent hypertension by inhibiting oxidative stress.

Conclusions:

Chloride channels are critical regulators of vascular remodeling and stroke.
Targeting specific Cl(-) channels presents a promising avenue for novel stroke therapies.
Further research into Cl(-) channel function is essential for developing effective stroke prevention and treatment strategies.
