Conclusion
Given the obtained results in comparison with previous research, the future clinical development of DMAPT could result in the expansion of new anti-inflammatory therapeutics for FMF disorder.
Methods
The effects of DMAPT and colchicine on metabolic activity and apoptosis of FMF-derived PBMCs were evaluated by MTT and Annexin V/PI assays, respectively. Also, the expression levels of NF-κB, NLRP3, MEFV, CASP1, and IL-1β mRNA were investigated using a TaqMan real-time PCR, and the protein levels of IL-1β, IL-18, and IL-37 were assessed via an enzyme-linked immunosorbent assay (ELISA) in LPS/ ATP-stimulated PBMCs.
Results
DMAPT decreased the expression levels of NFκB (0.38±0.096, P<0.0001), NLRP3 (0.39±0.12, P<0.001), MEFV (0.384±0.145, P<0.001), CASP1 (0.48±0.13, P=0.0023), and IL-1β (0.09±0.09, P<0.0001) and reduced the secretion levels of IL-1β (8.92±5.3 vs. 149.85±20.92, P<0.0001), IL-18 (135±32.1 vs. 192±22.18, P=0.01), and IL-37 (27.5±6.3 vs. 78.19±14.3, P<0.0001) as compared to untreated cells.
