RESUMO

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic inflammation and joint destruction, leading to significant morbidity and reduced quality of life. Although significant progress has been made in the management of RA over the past few decades, many patients still fail to respond adequately to currently available therapies. This article aims to review the current landscape of RA treatment and explore potential novel therapeutic approaches that hold promise for the future. Advances in our understanding of the underlying pathogenesis of the disease have led to the identification of new targets and the development of innovative treatment strategies. This review focuses on emerging therapies including small molecule inhibitors, targeted biologics, cell-based therapies, and gene editing technologies that have shown potential in preclinical and early clinical trials. Additionally, we discuss the challenges and opportunities associated with the use of these new approaches in the treatment of RA. By elucidating the future of novel therapeutic approaches, this article provides insights that can guide clinicians and researchers in their efforts to improve outcomes for patients with RA.

RESUMO

Mycoplasma ovipneumoniae is associated with chronic non-progressive pneumonia of sheep and goats. As with many other mycoplasmas involved in animal diseases, protective immune responses have not been achieved with vaccines, even though antibody responses can be obtained. This study focuses on characterizing the interaction of M. ovipneumoniae with ovine PBMC using carboxy-fluorescein-succinimidyl-ester (CFSE) loading and flow cytometry to measure lymphoid cell division. M. ovipneumoniae induced a strong in vitro polyclonal suppression of CD4(+), CD8(+), and B blood lymphocyte subsets. The suppressive activity could be destroyed by heating to 60 degrees C, and partially impaired by formalin and binary ethyleneimine treatment that abolished its viability. The activity resided on the surface-exposed membrane protein fraction of the mycoplasma, since mild trypsin treatment not affecting viability was shown to reduce suppressive activity. Trypsin-treated mycoplasma regained suppressive activity once the mycoplasma was allowed to re-synthesize its surface proteins. Implications for the design of vaccines against M. ovipneumoniae are discussed.
