Insights

Osteoarthritis therapies targeting G-protein coupled receptors (GPCRs) show promise for managing cartilage degeneration and pain. This review explores GPCRs as therapeutic targets for osteoarthritis, highlighting challenges and potential strategies.

Area of Science:

  • Rheumatology and Pharmacology
  • Molecular Biology and Biochemistry

Background:

  • Osteoarthritis (OA) is a prevalent chronic joint disease causing significant disability.
  • Current OA treatments lack disease-modifying capabilities.
  • G-protein coupled receptors (GPCRs) play critical roles in OA pathogenesis, including cartilage breakdown, bone changes, and pain.

Purpose of the Study:

  • To review pathophysiological processes in OA targeted by GPCRs.
  • To examine preclinical and clinical data related to GPCRs in OA.
  • To identify promising GPCR targets for novel OA therapies.

Main Methods:

  • Literature review of scientific publications and clinical trial data.
  • Analysis of the role of various GPCRs in OA.
  • Identification of therapeutic strategies targeting specific GPCRs.

Main Results:

  • GPCRs are implicated in OA cartilage degeneration, subchondral bone sclerosis, and chronic pain.
  • Examples of therapeutic GPCR targets include receptors for cannabinoids, hormones, prostaglandins, fatty acids, adenosine, and chemokines.
  • Preclinical and clinical data support the potential of targeting these GPCRs.

Conclusions:

  • GPCRs represent a significant area for developing disease-modifying OA therapies.
  • Targeting specific GPCRs offers potential strategies to combat OA progression and associated pain.
  • Further research and development are needed to overcome challenges in translating these therapies to clinical practice.

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

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.

G Protein-coupled 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...

Transducer Mechanism: G Protein–Coupled Receptors

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.
GPCRs are also called heptahelical,...

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...

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

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...

GPCR Desensitization01:12

GPCR Desensitization

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...
