Bcl-2 family members play an active role in the regulation of mitochondrial dynamics, mitochondrial respiration, metabolism, and apoptotic resistance.49, 50, 51, 52 In this study, real-time PCR and ELISA were used to measure the expression and protein levels of mitochondrial fusion/fission proteins in PBMCs from BD patients. This evidence concerns the gene BCL2 and Behcet disease.
