Project description:Intent of this experiment is to define the baseline transcriptome of the synovium obtained from rheumatoid arthritis patients prior to initiation of DMARD (Disease-modifying antirheumatic drug) therapy and compare it with the synovial transcriptome of rheumatoid arthritis patients with an established disease profile.
Project description:Synovial biopsies of Rheumatoid Arthritis patients with active disease were obtained prior to anti-TNF therapy. Clinical response to anti-TNF treatment was measured 20 weeks later using the EULAR response criteria. Gene expression profiles of patients responding to anti-TNF therapy were compared to non-responders and several genes were found to be differentially expressed between both groups of Rheumatoid Arthritis patients.
Project description:Leukocytapheresis((LCAP) is a safe, unique therapy prevalent for intractable rheumatoid arthritis even in case of drug allergy or infectious state. To investigate how to improve LCAP efficacy, we have conducted genes expressions analysis from peripheral blood of Rheumatoid arthritis patients using high resolution DNA microarray just before and after LCAP procedure. 8 Rheurmatoid arthritis patients have been compared just before and after Leukocytapheresis treatment (overall 16 samples). The Pre-LCAP samples were labeled using Cy5, and the Post-LCAP labeled with Cy3.
Project description:Synovial biopsies of Rheumatoid Arthritis patients were obtained at week 20 of anti-TNF therapy. The clinical response to therapy was determined comparing the DAS28 at this time point with the baseline DAS28, using the EULAR response criteria. Gene expression profiles of patients responding to anti-TNF therapy were compared to non-responders and different genes, pathways and deconvoluted cell types were found to be differential between both groups of rheumatoid arthritis patients.
