Summary
G protein-coupled receptors (GPCRs) regulate inflammation by mediating immune cell movement and responding to anti-inflammatory signals. Targeting these GPCRs offers potential for new inflammation therapies.
Area of Science:
- Immunology
- Pharmacology
- Cell Biology
Background:
- G protein-coupled receptors (GPCRs) are crucial for human physiology and immunoregulation.
- GPCRs mediate inflammatory responses, including immune cell chemotaxis via chemokines.
- Certain GPCRs transduce anti-inflammatory signals, promoting inflammation resolution.
Purpose of the Study:
- To review current knowledge on GPCRs involved in anti-inflammatory and pro-resolving pathways.
- To summarize GPCR structures, signaling mechanisms, and therapeutic potential.
- To highlight knowledge gaps in understanding these GPCR signaling pathways.
Main Methods:
- Literature review of GPCRs interacting with lipid mediators.
- Analysis of GPCR signaling pathways in inflammation resolution.
- Exploration of therapeutic targeting strategies for anti-inflammatory GPCRs.
Main Results:
- GPCRs for chemoattractants guide phagocyte and lymphocyte migration to inflammatory sites.
- GPCRs interacting with lipoxins, resolvins, and protectins promote inflammation resolution.
- Signaling mechanisms of these anti-inflammatory GPCRs require further elucidation.
Conclusions:
- GPCRs play dual roles in inflammation: mediating inflammatory cell recruitment and resolving inflammation.
- Targeting specific GPCRs offers a promising avenue for developing novel anti-inflammatory therapies.
- Further research into GPCR signaling pathways is essential for optimizing therapeutic strategies.

01:09GPCRs Regulate Adenylyl Cylase Activity
6.6K
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...

01:22Amplifying Signals via Enzymatic Cascade
15.9K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

01:19Interactions Between Signaling Pathways
7.0K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:15G Protein-coupled Receptors
15.5K
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...

01:20The JAK-STAT Signaling Pathway
10.9K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:28Inflammatory Response
15.4K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
