Enhanced type 1 interferon signature in axial spondyloarthritis patients unresponsive to secukinumab treatment

Arthritis Rheumatol 2024 Epub ahead of print doi: 10.1002/art.42974

Pacheco et al. demonstrated that, compared with axSpA patients who respond to secukinumab,  patients who do not respond show increased IL-17A-producing cells and have a more pronounced type 1 IFN signature, indicating a larger inflammatory burden.

AG490, farelerde JAK2-STAT3 inhibisyonu yaparak T reg ve Th17 hücrelerinin resiprok regülasyonu aracılığıyla Otoimmün Artriti baskılar

J Immunol 2014; 192:4417-4424

In this study, Park et al sought to investigate the effects of the JAK2 inhibitor, AG490 in RA. Using murine CIA models, both preventative and therapeutic models were investigated. In the preventative model, CIA mice treated with AG490 showed a significantly lower incidence rate of arthritis and arthritic scores when compared to mice injected with vehicle. In the therapeutic model, as in the preventative, AG490 treated mice exhibited less severe arthritis. Through further experiments, it was dem...

STA-21, gelecek vadeden STAT3 inhibitörü olup Th17 ve Treg resiprok olarak düzenler, osteoklastogenezi inhibe eder ve otoimmün inflamasyonu iyileştirir

Arthritis and Rheumatism doi: 10.1002/art.38305

STAT3 (signal transducer and activator of transcription 3) is the major transcription factor in the differentiation of Th17 cells, which along with IL-17 are significant in the development of RA. STA-21 is a new small molecule with significant inhibitory effects on STAT3, impeding DNA binding activity, dimerization and STAT3-dependent luciferase activity. While the effect of STA-21 in RA has not been fully determined, it has been hypothesised that STA-21 will suppress arthritis in animal models ...
