Summary
Adhesion G protein-coupled receptors (aGPCRs) are crucial for cell adhesion and immune responses. Recent research highlights their roles in regulating inflammation and innate immunity.
Area of Science:
- Molecular Biology
- Immunology
- Cell Biology
Background:
- Adhesion G protein-coupled receptors (aGPCRs) are a major class of GPCRs with unique extended ectodomains.
- These receptors possess protein-protein interaction domains, suggesting roles in cellular adhesion.
- Many aGPCRs undergo autoproteolytic cleavage, forming bipartite structures crucial for their function.
Purpose of the Study:
- To review current knowledge on aGPCRs in immune responses and inflammation.
- To discuss the roles of aGPCRs in hematopoietic cells and their impact on immune cell populations.
- To explore the mechanisms of aGPCR activation and signal transduction in the context of immunity.
Main Methods:
- Literature review of recent studies on aGPCRs.
- Analysis of aGPCR expression patterns in hematopoietic cells.
- Discussion of functional studies implicating aGPCRs in immune regulation.
Main Results:
- Approximately one-third of human aGPCRs are expressed in hematopoietic cells, defining distinct populations.
- aGPCRs play significant roles in controlling innate effector functions.
- Emerging evidence links aGPCRs to the susceptibility and onset of inflammatory and autoimmune conditions.
Conclusions:
- aGPCRs are critical regulators of immune responses and inflammation.
- Further research into aGPCR mechanisms can provide insights into immune cell function and disease pathogenesis.
- Targeting aGPCRs may offer therapeutic strategies for inflammatory and autoimmune diseases.

7.7K
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...

01:15G Protein-coupled Receptors
18.1K
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...

4.5K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:24Adherens Junctions
6.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

10.1K
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

8.4K
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...
