Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Enzyme Inhibition

Enzyme Inhibition

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
Although all competitive neuromuscular blockers are designed...

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action

Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

Combined Effects of Drugs: Antagonism

Combined Effects of Drugs: Antagonism

The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...

Background:

Coordinated excitatory and inhibitory activity is essential for brain function.
Recurrent cortical networks exhibit activity patterns largely dominated by inhibition.
Inhibitory plasticity has been traditionally viewed for homeostatic control.

Purpose of the Study:

To propose a new framework where inhibition is a primary driver of network activity.
To emphasize the role of context-dependent modulation and plasticity of inhibitory connections.
To highlight the dynamic and activity-dependent nature of the excitation-inhibition balance.

Main Methods:

Computational modeling of neuronal networks.
Analysis of activity patterns in recurrent cortical networks.
Review of experimental studies on inhibitory plasticity.

Main Results:

Inhibitory activity patterns dominate recurrent cortical networks.
Inhibitory plasticity is crucial for context-dependent modulation.
Synaptic plasticity is often multisynaptic and influences the excitation-inhibition balance.

Conclusions:

Inhibition is a key driver in complex neuronal networks, not just a homeostatic regulator.
The balance between excitation and inhibition is dynamic, context-dependent, and activity-level dependent.
Understanding inhibitory plasticity is critical for insights into memory and learning.
