Sphingosine-1-phosphate (S1P) plays an important role in trafficking leukocytes and developing immune disorders including autoimmunity. In the synovium of rheumatoid arthritis (RA) patients, increased expression of S1P was reported, and the interaction between S1P and S1P receptor 1 (S1P1) has been suggested to regulate the expression of inflammatory genes and the proliferation of synovial cells. In this study, we investigated the level of S1P1 mRNA expression in the blood leukocytes of RA patients. In contrast to the previous reports, the expression level of this gene was not correlated to their clinical scores, disease durations and ages. However, S1P1 was transcribed at a significantly lower level in the circulating leukocytes of RA patients when compared to age-, and sex-matched healthy controls. Since these data may suggest the participation of S1P1, further studies are needed to determine the role of this receptor in the pathogenesis of RA.

Background: Diabetes mellitus (DM) and arthritis are prevalent conditions worldwide. The intricate relationship between these two conditions, especially in the context of various subtypes of arthritis, remains a topic of interest.
Objective: To investigate the relationship between diabetes and arthritis, with a focus on Rheumatoid Arthritis (RA), using data from the National Health and Nutrition Examination Survey (NHANES) and Mendelian Randomization (MR) analysis.

Objectives: The effects of systemic inflammation on the temporomandibular joint (TMJ) are poorly understood. This study aimed to establish a mouse model to study the effects of systemic inflammation on the TMJ.
Materials And Methods: SKG mice, a BALB/c strain with spontaneous onset of rheumatoid arthritis-like symptoms due to a spontaneous point mutation (W163C) in the gene encoding the SH2 domain of ZAP-70, were treated with zymosan (β-1,3-glucan).

Background: Effective disease management is crucial for rheumatoid arthritis (RA) patients as it can significantly reduce disease-associated symptoms. Currently, the utilization of mobile applications for managing RA patients has gained widespread popularity in clinical settings. However, there is a notable absence of a comprehensive meta-analysis exploring their effectiveness specifically in the context of RA patients.

Background/objective: Rheumatic diseases (RMDs) are among the leading health burdens and causes of disability globally. Interestingly, they are on the rise due to the increasingly ageing population. Inflammatory RMDs are not left behind in the rise, especially in Africa, where they were thought to be rare as there has been increasing reportage of these diseases in recent years.

Objectives: Little is known about how various treatments impact the progression of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients. Here, we compared ILD progression in RA patients treated with Janus kinase inhibitors (JAKi) or biological disease-modifying anti-rheumatic drugs (bDMARDs). experiments were also performed to evaluate the potential effects of the drugs on epithelial-mesenchymal transition (EMT), a key event in pulmonary fibrosis.
