G protein–coupled receptor kinase 2 is increased in OA, and inhibition by the antidepressant paroxetine prevents disease progression. An antidepressant for arthritis? Pathological chondrocyte hypertrophy contributes to osteoarthritis (OA), a degenerative disease of the cartilage and bone. Carlson et al. studied the role of G protein–coupled receptor kinase 2 (GRK2), which is linked to cardiac hypertrophy, in OA. GRK2 was elevated in chondrocytes in mouse models of OA and in injured human… Expand

In a surgical model of osteoarthritis (OA), chondrocyte-specific deletion of GRK2, or pharmacological inhibition with the repurposed FDA-approved antidepressant drug paroxetine, attenuated chondROcyte hypertrophy, matrix degradation and OA progression. Expand


Proteinase-activated receptor 2 modulates OA-related pain, cartilage and bone pathology
This study clearly demonstrates PAR2 plays a critical role, via chondrocytes, in osteophyte development and subchondral bone changes, which occur prior to PAR2-mediated cartilage damage, which likely occurs independently of OA-related bone changes. Expand
Histone deacetylase 4 alters cartilage homeostasis in human osteoarthritis
The findings suggest that the abnormal expression of HDAC4 in osteoarthritic cartilage might be implicated in promoting catabolic activity of chondrocyte, which is associated with OA pathogenesis. Expand
Fluoxetine ameliorates cartilage degradation in osteoarthritis by inhibiting Wnt/β-catenin signaling
Fluoxetine, an antidepressant in the class of selective serotonin reuptake inhibitors (SSRI), down-regulated Wnt/β-catenin signaling in human chondrosarcoma cells and suppressed LiCl-induced β- catenin accumulation in human OA chondrocytes. Expand
Endogenous adenosine maintains cartilage homeostasis and exogenous adenosine inhibits osteoarthritis progression
It is shown that concentrations of ATP and adenosine, its metabolite, fall after treatment of mouse chondrocytes and rat tibia explants with IL-1β, an inflammatory mediator thought to participate in OA pathogenesis. Expand
Chondrocyte hypertrophy and osteoarthritis: role in initiation and progression of cartilage degeneration?
It is proposed that altered chondrocyte behavior and concomitant cartilage degradation result in a disease-amplifying loop, leading to a mixture of disease stages and cellular responses within an OA joint, which plays a role in early and late stage OA. Expand
Emerging drugs for the treatment of knee osteoarthritis
Given the complexity of OA, one single therapy is unlikely to be universally and uniformly effective, and promising therapies are under development, but there are obstacles in the translation of treatment from preclinical models and trial designs need to be cognizant of the complex reasons for previous trial failures.

Small molecule disruption of G protein βγ subunit signaling reprograms human macrophage phenotype and prevents autoimmune myocarditis in rats
The data suggest that the small molecule Gβγ inhibitor, gallein, could be an important pharmacologic therapy for HF as it can switch the phenotypic reprogramming from M1 to M2 phenotype in a rat model of EAM heart and in human macrophages. Expand
Serotonin 5HT2A receptor antagonism mediated anti-inflammatory and anti-fibrotic effect in adriamycin-induced CKD in rats
Ketanserin reduces renal fibrosis and inflammation in adriamycin-induced chronic kidney disease by suppressing 5-HT2A, IL-6, TGF-β and collagen IV expression in renal tissue. Expand
Paroxetine alleviates T lymphocyte activation and infiltration to joints of collagen-induced arthritis
This study elucidates that paroxetine attenuates the symptoms of CIA rats due to its inhibitory effect on T cell activation and infiltration to synovial tissue via suppression of ERK pathway. Expand
Paroxetine and rivastigmine mitigates adjuvant‐induced rheumatoid arthritis in rats: Impact on oxidative stress, apoptosis and RANKL/OPG signals
Paroxetine and rivastigmine possess antirheumatoid effects in CFA‐induced RA which is mediated through antioxidant, anti‐inflammatory, antiapoptotic and modulation of RANKL/OPG expression levels. Expand
