Osteoarthritis (OA) is the most common form of arthritis worldwide yet there is still a lack of effective treatments for this condition. Increasingly, attention has turned to the role of the synovium in OA as it is now recognized, in part from the use of modern imaging techniques, that synovitis is both common and associated with pain. This offers a target for treatment, for both symptom and potential structure modification. In this review we discuss the evidence for histological and imaging-detected synovitis and the current role of antisynovial therapies in OA.

Objective: To study the effect of CCR1 and its ligands on macrophage polarization and evaluate its effect on chondrocytes in relieving the progression of osteoarthritis.
Methods: RAW cells were polarized to M1/M2 subtype, and then different concentrations of BX471 were added to selectively inhibit CCR1. The polarization of the cells was detected by RT-qPCR, immunofluorescence and flow cytometry.

Purpose: Recurrent diffuse-type tenosynovial giant cell tumor: Clinical presentation, Diagnosis, and Management.
Background: Tenosynovial giant cell tumor (TGCT), is a neoplasm arising from synovial joints, bursae, or tendon sheaths. The initial clinical symptoms are vague and non-diagnostic.

[F]FDG PET/TC is an emerging tool in the evaluation of inflammatory arthropathies, characterised by their insidious course and clinical overlap. It allows detection of subclinical inflammation, assessment of systemic involvement and quantification of metabolic parameters useful in early diagnosis and therapeutic monitoring. In rheumatoid arthritis, it correlates with clinical indices (Disease Activity Score), serological markers (CRP, anti-citrullinated protein antibodies) and ultrasound findings, and facilitates the identification of complications such as cardiovascular and pulmonary involvement.

Elevated synovial expression of the triggering receptor expressed on myeloid cells 1 (TREM1) has been identified as a significant biomarker for assessing disease activity in rheumatoid arthritis (RA). The upregulated expression of TREM1, induced by inflammatory mediators in infiltrating macrophages, plays a critical role in synovitis and joint destruction in RA. Our previous sequencing data linked TREM1 activation to aberrant mitophagy.

Introduction: Psoriatic arthritis (PsA) is a complex condition within the Spondyloarthritis (SpA) group. Recent studies have focused on the important role of the intestinal microbiota in maintaining immunological homeostasis, highlighting how intestinal dysbiosis may act as a trigger for autoimmune diseases. Tofacitinib is a Janus kinase inhibitor (JAK-i) with proven efficacy for the treatment of both rheumatoid arthritis and PsA.
