Summary
Researchers developed a new method to detect G-protein coupled receptor (GPCR) messenger RNAs (mRNAs) in cells. This technique successfully profiled GPCRs in various white blood cells and platelets, revealing previously undetected receptors.
Area of Science:
- Molecular Biology
- Cell Biology
- Immunology
Background:
- G-protein coupled receptors (GPCRs) are crucial cell surface proteins involved in numerous physiological processes.
- Detecting GPCRs is challenging due to low messenger RNA (mRNA) abundance and limitations of current high-throughput methods.
Purpose of the Study:
- To develop and validate a sensitive, specific, and semi-quantitative method for detecting GPCR transcripts.
- To profile GPCR mRNA expression in various human white blood cells and platelets.
Main Methods:
- Development of a novel sensitive assay for detecting low-abundance GPCR mRNAs.
- Application of the assay to profile GPCR transcripts in isolated populations of white blood cells (B, CD4, CD8, NK, dendritic cells, monocytes) and platelets.
- Analysis of GPCR mRNA expression levels across different cell types.
Main Results:
- The developed method reliably detected GPCR transcripts, overcoming limitations of existing techniques.
- White blood cells expressed a significant number of GPCR mRNAs, averaging 160 per cell type (range: 123-206).
- Platelets expressed a lower number of GPCR mRNAs (69), with some receptors not previously identified in these cells.
Conclusions:
- The novel method provides a sensitive and specific approach for profiling GPCR transcripts.
- The study identified a broad repertoire of GPCRs in white blood cells and platelets, expanding our understanding of their molecular landscape.
- These findings are expected to facilitate further research into GPCR functions and contribute to novel drug development strategies targeting these receptors.

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...

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

6.8K
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...

01:11IP3/DAG Signaling Pathway
11.9K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

01:15Amplifying Signals via Second Messengers
6.8K
Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
