Abstract:
Osteoarthritis (OA) is the most common chronic joint disease characterized, for which there are no available therapies being able to modify the progression of OA and prevent long-term disability. Critical roles of G-protein coupled receptors (GPCRs) have been established in OA cartilage degeneration, subchondral bone sclerosis and chronic pain. In this review, we describe the pathophysiological processes targeted by GPCRs in OA, along with related preclinical model and/or clinical trial data. We review examples of GPCRs which may offer attractive therapeutic strategies for OA, including receptors for cannabinoids, hormones, prostaglandins, fatty acids, adenosines, chemokines, and discuss the main challenges for developing these therapies.
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.
