Drug-Receptor Interactions01:29

Drug-Receptor Interactions

Drug-receptor interaction describes the binding of receptors by drugs, but not all drug-receptor interactions result in activation and tissue response. For instance, the binding of agonists activates the receptor to generate a cellular reaction, while antagonists bind to receptors without causing their activation.
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue.
Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence the...

The Two-State Receptor Model01:29

The Two-State Receptor Model

The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.
The binding affinity of a drug determines its interaction with one...
Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Activation and Inactivation of G Proteins01:22

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...

Summary
This summary is machine-generated.

Human action control involves automatically linking movements with their sensory outcomes. This study shows that even brief action-effect links influence subsequent behavior, especially when attention is focused.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human Action Control

Background:

  • Ideomotor theories posit automatic integration of motor commands and perceptual consequences.
  • Understanding the rapid formation and influence of action-effect bindings is crucial for explaining human behavior.

Purpose of the Study:

  • To investigate the microgenesis of action-effect integration.
  • To examine how trial-to-trial variations in action-effect mapping influence behavior.
  • To explore the role of attentional factors in action-effect integration and retrieval.

Main Methods:

  • Participants performed actions with varying mappings to perceptual effects (e.g., tones).
  • Behavioral responses were analyzed to assess the influence of prior action-effect contingencies.
  • Attentional modulation was investigated by manipulating stimulus salience and attentional set.

Main Results:

  • Perceiving a repeated tone systematically biased participants towards repeating the action that produced it.
  • This suggests a temporary binding between an action and its unintentional perceptual consequence.
  • Action-effect integration and retrieval were significantly modulated by attentional factors, such as stimulus salience and matching attentional sets.

Conclusions:

  • Even unintentional stimulus production leads to rapid action-effect binding.
  • Attentional processes play a key role in modulating the impact of action effects on ongoing performance.
  • Findings support and extend ideomotor theories by detailing the dynamic nature of action-effect integration.
