G Protein-coupled Receptors01:15

G Protein-coupled Receptors

12.1K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Phosphoinositides and PIPs01:42

Phosphoinositides and PIPs

8.5K
Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

Transducer Mechanism: Enzyme-Linked Receptors

2.5K
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

GPCR Desensitization01:12

GPCR Desensitization

6.0K
G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...

Nitric Oxide Signaling Pathway01:28

Nitric Oxide Signaling Pathway

5.0K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

5.6K
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Cell Biology

Background:

  • Purinergic and pyrimidinergic signaling molecules, including adenosine triphosphate (ATP) and its derivatives, are crucial for synchronizing cellular functions across human and animal bodies.
  • These signaling molecules are particularly vital in the central and peripheral nervous systems, where they are released by both neural (neurons, astrocytes, oligodendrocytes) and non-neural cells (e.g., vascular endothelium).
  • A wide array of purinergic receptors mediates cellular responses to these extracellular nucleotides and nucleosides, forming the basis of intercellular communication.

Discussion:

  • The collection of papers reviews current knowledge on the medicinal chemistry, electrophysiology, neuropharmacology, and neurobiology of purinergic transmission.
  • Emerging evidence strongly implicates extracellular nucleotides and nucleosides in the pathogenesis of neuroinflammation, neurodegeneration, and neuropsychiatric disorders.
  • The development of novel, brain-permeant, drug-like purinergic ligands is crucial for therapeutic intervention.

Key Insights:

  • Extracellular nucleotides and nucleosides are key regulators of neural network activity.
  • Purinergic signaling plays a significant role in neuroinflammation, neurodegeneration, and neuropsychiatric diseases.
  • Novel purinergic ligands offer potential therapeutic strategies for currently untreatable neurological and psychiatric conditions.

Outlook:

  • Further research into purinergic signaling mechanisms will advance our understanding of complex neurological functions.
  • Development of targeted purinergic therapies holds promise for treating a range of central and peripheral nervous system disorders.
  • This field is poised to open new therapeutic avenues for debilitating neurological and psychiatric diseases.
