Premature SC activation before injury both accelerated myogenic repair and disrupted NMJ remodeling and maturation, possibly by reducing Sema3A neuro-repulsion and altering S100B. This interpretation extends the model of Sema3A-mediated motoneuritogenesis during muscle regeneration. Manipulating the timing and type of Sema3A by brief NO effects on SCs suggests an important role for TSCs and Sema3A-65 processing in axon guidance and NMJ restoration during muscle repair.BACKGROUND The purpose of this study was to evaluate a new pharmacological strategy using a first generation succinate prodrug, NV118, in peripheral blood mononuclear cells (PBMCs) obtained from subjects with carbon monoxide (CO) poisoning and healthy controls. We obtained human blood cells from subjects with CO poisoning and healthy control subjects. Intact PBMCs from subjects in the CO and Control group were analyzed with high-resolution respirometry measured in pmol O2 × s-1 × 10-6 PBMCs. In addition to obtaining baseline respiration, NV118 (250 mM) was injected and the same parameters of respiration were obtained for comparison in PBMCs. We measured mitochondrial dynamics with microscopy with the same conditions. RESULTS We enrolled 37 patients (17 in the CO group and 20 in the Control group for comparison) in the study. PMBCs obtained from subjects in the CO group had overall significantly lower respiration compared to the Control group (P less then 0.0001). There was a significant increase in respiration with NV118, specifically with an increase in maximum respiration and respiration from Complex II and Complex IV (P less then 0.0001). The mitochondria in PBMCs demonstrated an overall increase in net movement when compared to the Control group. CONCLUSIONS Our results of thi
