The Charcot-Marie-Tooth disease 2F (CMT2F) and distal hereditary motor neuropathy 2B (dHMN2B) are caused by autosomal\ndominantly inherited mutations of the heat shock 27 kDa protein 1 (HSPB1) gene and there are no specific therapies available yet.\nHere, we assessed the potential therapeutic effect of HDAC6 inhibitors on peripheral neuropathy with HSPB1 mutation using in\nvitro model of motor neurons derived from induced pluripotent stem cells (iPSCs) of CMT2F and dHMN2B patients. The absolute\nvelocity of mitochondrial movements and the percentage of moving mitochondria in axons were lower both in CMT2F-motor\nneurons and in dHMN2B-motor neurons than those in controls, and the severity of the defective mitochondrial movement was\ndifferent between the two disease models. CMT2F-motor neurons and dHMN2B-motor neurons also showed reduced
