Two monoclonal IgG rheumatoid factors were obtained after hybridization of spleen cells from DBA/1 mice immunized with immune complexes containing native collagen type II and a monoclonal anti-collagen II antibody. One of these rheumatoid factors reacted not only with purified murine Fc fragments, but also with Fab fragments of the anti-collagen II antibody used for immunization, whereas no reactivity was seen with Fab fragments from normal mouse IgG. The findings demonstrate the ability of immune complexes encompassing native collagen type II to induce production of IgG rheumatoid factors, and suggest that an idiotypic relationship may exist between certain rheumatoid factors and anti-collagen II antibodies.

Introduction: TNFα inhibitor (TNFi) immunogenicity in rheumatoid arthritis (RA) is a major obstacle to its therapeutic effectiveness. Although methotrexate (MTX) can mitigate TNFi immunogenicity, its adverse effects necessitate alternative strategies. Targeting nuclear factor of activated T cells (NFAT) transcription factors may protect against biologic immunogenicity.

Rheumatoid arthritis (RA) is a progressive autoimmune disease leading to structural and functional joint damage and, eventually, to physical disability. The pathogenesis of the disease is highly complex and involves interactions between fibroblast-like synoviocytes (FLSs) and immune cells, which stimulate the secretion of pro-inflammatory factors, leading to chronic inflammation. In recent years, studies have demonstrated the importance of epigenetics in RA.

Objectives: Physical function in RA is largely influenced by multiple clinical factors, however, there is a growing body of evidence that psychological state and other comorbidities also play an essential role. Using data obtained in the COVID-19 Vaccination in Autoimmune Diseases study, an international self-reported e-survey, we aimed to explore the predictive ability of sociodemographic and clinical variables on Patient-Reported Outcomes Measurement Information System Physical Function Short Form 10a (PROMIS PF-10a) in RA and to investigate variation in disease activity and functional outcomes based on country-level socio-economic parameters.
Methods: Patient demographics, disease characteristics including current symptom status, functional status and treatment variables, as well as income level of the country of residence, were extracted from survey responses.

Toll-Like Receptors (TLRs) is a pattern recognition receptor that connects innate and adaptive immunity and participates in inflammatory responses play a key role in common autoimmune diseases such as Rheumatoid Arthritis (RA), systemic lupus erythematosus (SLE), psoriasis, and Sjögren's syndrome (SS) by participating in antigen recognition, immune cell activation, and inflammatory factor release. Due to the multi-component and multi-target characteristics of traditional Chinese medicine (TCM), the role of TCM active ingredients acting on TLRs has been widely studied. This article describes the relationship between TLR and four autoimmune diseases, as well as a review of the efficacy of TLR intervention by active ingredients of traditional Chinese medicine.
