The result showed that the activity of Th1 immune response tent to be higher in patient with WHO class III and IV LN. The frequency of IFNG 112 allele were higher in patients with SLE compared with healthy controls and the risk to have jak stat LN class V in patients with IFNG 112 was 6 times higher compared with patients without these allele. The results showed different underlying mechanism of inflammation in different pathologic class of LN. After the breakthrough in the treatment of rheumatoid arthritis and numerous related disorders with biological therapies targeting TNFa at the Kennedy Institute in London Millions of patients have tremendously benefitted. However, we cannot cure these diseases yet and have to search for additional therapeutic targets.

Since it was shown that synovial purchase Everolimus fibroblasts are not only effector cells responding to inflammatory stimuli, but appear endogenously activated and potentially involved into spreading the disease, we searched for the epigenetic modifications leading to the activated phenotype of these cells. Epigenetics in its scientific definition is the study of all heritable and potentially reversible changes in genome function that do not alter the nucleotide sequence within the DNA, but might be considered in simpler terms as the regulation of gene expression. Epigenetic modifications include: Acetylation, Methylation, Phosphorylation, Sumoylation, miRs or microRNAs. Our laboratory is studying these processes and we have found that RASF reside in a hyperacetylated synovial tissue and appear hypomethylated.

Hypomethylation leads to the activated phenotype of RASF which is characterized by the production of matrix degrading enzymes and of potent chemokines induced by Toll like receptor signalling. Chromoblastomycosis Current strategies are designed to methylate these cells to deactivate and normalise them again. miRs are about 20 nucleotide long smallRNAs acting to destroy specific mRNA. In the race to identify specific miRs as novel targets we have identified for example, that interleukin 6 modulates the expression of the Bone Morphogenic Protein Receptor Type II through a novel STAT3microRNA cluster 17/92 pathway, which helps to explain the loss of the BMPR2 in the vascular cells in pulmonary hypertension. Moreover, miR 203 is regulating the production of IL 6.

Rheumatology has pioneered in the study of autoantibodies by showing that they are not only involved in pathogenesis but are also highly useful as diagnostic research chemicals library biomarkers. The diagnostic biomarker aspect of autoimmunity has gained increasing importance in cancer and many of the insights gained in Rheumatology have contributed to understanding the significance of autoantibodies in cancer. Features of autoantibodies in rheumatic disorders: In rheumatic diseases no individual autoantibody antigen system has sufficient combination of sensitivity and specificity to serve as a useful diagnostic biomarker. Instead, several antigen antibody systems constructed as profiles of biomarkers are highly effective in distinguishing one disorder from another.
