Mechanosignalling in cartilage: an emerging target for the treatment of osteoarthritis | Nature Reviews Rheumatology

Mechanosignalling in cartilage: an emerging target for the treatment of osteoarthritis | Nature Reviews Rheumatology | Rheumatology-Rhumatologie | Scoop.it
Mechanical stimuli have fundamental roles in articular cartilage during health and disease. Chondrocytes respond to the physical properties of the cartilage extracellular matrix (ECM) and the mechanical forces exerted on them during joint loading. In osteoarthritis (OA), catabolic processes degrade the functional ECM and the composition and viscoelastic properties of the ECM produced by chondrocytes are altered. The abnormal loading environment created by these alterations propagates cell dysfunction and inflammation. Chondrocytes sense their physical environment via an array of mechanosensitive receptors and channels that activate a complex network of downstream signalling pathways to regulate several cell processes central to OA pathology. Advances in understanding the complex roles of specific mechanosignalling mechanisms in healthy and OA cartilage have highlighted molecular processes that can be therapeutically targeted to interrupt pathological feedback loops. The potential for combining these mechanosignalling targets with the rapidly expanding field of smart mechanoresponsive biomaterials and delivery systems is an emerging paradigm in OA treatment. The continued advances in this field have the potential to enable restoration of healthy mechanical microenvironments and signalling through the development of precision therapeutics, mechanoregulated biomaterials and drug systems in the near future. The pathways involved in sensing and responding to mechanical stimuli have important roles in maintaining cartilage health, and can contribute to disease when dysregulated. This Review discusses cartilage mechanosignalling pathways and how they can be targeted to treat osteoarthritis.

Best Practice Award winner: empowering patients living with inflammatory arthritis | British Society for Rheumatology

In the last of our series showcasing our Best Practice Award winners, we talk to the rheumatology team at North Bristol NHS Trust, who developed an education programme to help support arthritis patients. The rheumatology team at North Bristol NHS Trust won their Best Practice Award for their Living Well Pathway, developed to help patients living with inflammatory arthritis. The course was designed to support both physical and psychological wellbeing, empowering patients to feel more in control of their health. The project The project was set up to incorporate NICE guidelines, which state that patients should be offered education and self-management within one month of diagnosis and should be helped to adjust to their condition. The pathway is split into two parts; a Living Well event for newly diagnosed patients and a Living Well course for people who have been diagnosed for a year or more. Clinical psychologist Kate Druett, who helped set the programme up, said: “We wanted to make sure all our patients were aware of the different services available within our team to support them. We also wanted to be holistic and supportive in terms of both physical and emotional wellbeing.” The Living Well event has seen 77 patients attend since it began in March 2017: It's signposting and information session giving patients the opportunity to meet the rheumatology team and other patients with inflammatory arthritis During a series of interactive talks, patients can ask questions and find out what support is available, as well as what might help with managing their condition These run for 2.5 hours every other month and alternate between a morning or evening slot so it’s accessible for people who work. Attendees have found the inclusion of a talk by a patient volunteer particularly valuable; this provides a picture of their own experience, a talk about what they have found helpful in learning to live with the condition, and offers hope for the future. The Living Well course was completed by 56 patients between October 2017-September 2019. It: Is aimed at helping patients who are at least one-year post diagnosis cope with their symptoms Weekly course, seven sessions of 2.5 hours each Includes a two-month 'reunion' follow-up Covers issues like fatigue, stress, keeping active, and goal-setting. Kate explains: “We interchange who runs the course amongst the team, but we have representatives from Specialist Nursing, Occupational Therapy and Psychology.” Another key element is the social aspect and patients supporting each other in the community once the course comes to an end. Kate says: “Patients are encouraged to meet informally amongst themselves to help keep the momentum going and put what they've learnt into practice.” Following the course, many patients have reported an increase in confidence in knowing where to get help with their condition and have seen improvements in their mood. Kate says: “One of the key benefits we’ve seen is that people report a lift in their confidence. Before the course patients may have been struggling with fatigue or pain for some time and lost a lot of their confidence. They often tell us they feel low and isolated, finding day-to-day activities difficult, and often feel quite stuck.” She continues: “It’s been rewarding to hear how people have really valued the opportunity to meet and learn from others. Patients have often made many changes, such as taking regular time for themselves to swim or get back to day-to-day activities they used to enjoy, such as cooking. Others made changes at work so that it's more manageable, or made plans to return to work.” The team use an active and supportive group of volunteers to help them run the signposting event. Feedback and discussion with previous participants help with continued reviewing of the course content Kate explains: “They've contributed to the content based on their experience of what would have been helpful to them when they were diagnosed. We know people find strength and encouragement from hearing from other patients who have been through similar circumstances.”  What happens next? Post-pandemic, the team will restart the courses and will look at putting some of the content online. Kate says: “We’ve recorded some short films with our participants so that they can be used on our website to encourage other patients to get involved. Plus, we want to get some of the other useful information online.”. What did the judges say? The judges commended the team for helping patients take control of their health and have better outcomes. BSR’s Chief Executive, Ali Rivett, says: “I was particularly impressed by how patient-focused this initiative was. Patients are involved in the design and delivery of the programme, alongside their AHP team. Participant feedback is positive, with reported increases in patient activation measures alongside other key metrics.” Congratulations to all our winners, who are working hard to improve the lives of patients.

Frontiers | Anti-Mouse CD83 Monoclonal Antibody Targeting Mature Dendritic Cells Provides Protection Against Collagen Induced Arthritis | Immunology

Frontiers | Anti-Mouse CD83 Monoclonal Antibody Targeting Mature Dendritic Cells Provides Protection Against Collagen Induced Arthritis | Immunology | Rheumatology-Rhumatologie | Scoop.it
Antibodies targeting the activation marker CD83 can achieve immune suppression by targeting antigen-presenting mature dendritic cells (DC). This study investigated the immunosuppressive mechanisms of anti-CD83 antibody treatment in mice and tested its efficacy in a model of autoimmune rheumatoid arthritis. A rat anti-mouse CD83 IgG2a monoclonal antibody, DCR-5, was developed and functionally tested in mixed leukocyte reactions, demonstrating depletion of CD83+ conventional (c)DC, induction of regulatory DC (DCreg), and suppression of allogeneic T cell proliferation. DCR-5 injection into mice caused partial splenic cDC depletion for 2–4 days (mostly CD8+ and CD83+ cDC affected) with a concomitant increase in DCreg and regulatory T cells (Treg). Mice with collagen induced arthritis (CIA) treated with 2 or 6 mg/kg DCR-5 at baseline and every three days thereafter until euthanasia at day 36 exhibited significantly reduced arthritic paw scores and joint pathology compared to isotype control or untreated mice. While both doses reduced anti-collagen antibodies, only 6 mg/kg achieved significance. Treatment with 10 mg/kg DCR-5 was ineffective. Immunohistological staining of spleens at the end of CIA model with CD11c, CD83, and FoxP3 showed greater DC depletion and Treg induction in 6 mg/kg compared to 10 mg/kg DCR-5 treated mice. In conclusion, DCR-5 conferred protection from arthritis by targeting CD83, resulting in selective depletion of mature cDC and subsequent increases i

A new immunometabolic perspective of intervertebral disc degeneration | Nature Reviews Rheumatology

A new immunometabolic perspective of intervertebral disc degeneration | Nature Reviews Rheumatology | Rheumatology-Rhumatologie | Scoop.it
Intervertebral disc (IVD) degeneration is a common finding on spine imaging that increases in prevalence with age. IVD degeneration is a frequent cause of low back pain, which is a leading cause of disability. The process of IVD degeneration consists of gradual structural change accompanied by severe alterations in metabolic homeostasis. IVD degeneration, like osteoarthritis, is a common comorbidity in patients with obesity and type 2 diabetes mellitus, two metabolic syndrome pathological conditions in which adipokines are important promoters of low-grade inflammation, extracellular matrix degradation and fibrosis. Impairment in white adipose tissue function, due to the abnormal fat accumulation in obesity, is characterized by increased production of specific pro-inflammatory proteins such as adipokines by white adipose tissue and of cytokines such as TNF by immune cells of the stromal compartment. Investigations into the immunometabolic alterations in obesity and type 2 diabetes mellitus and their interconnections with IVD degeneration provide insights into how adipokines might affect the pathogenesis of IVD degeneration and impair IVD function and repair. Toll-like receptor-mediated signalling has also been implicated as a promoter of the inflammatory response in the metabolic alterations associated with IVD and is thus thought to have a role in IVD degeneration. Pathological starvation, obesity and adipokine dysregulation can result in immunometabolic alterations, which could be targeted for the development of new therapeutics. In this Review, the authors discuss the immunometabolic alterations involved in the pathogenesis of intervertebral disc degeneration, including the role of adipokines in impaired metabolism in intervertebral disc cells, and discuss opportunities for future research and development of new therapies.
