For example, Sheykhhasan et al. recently showed that CoQ10 delivery via adipose-derived stem cell exosomes is more efficient than CoQ10 alone in stimulating the memory and increasing the hippocampal expression of BDNF and SRY-box transcription factor 2 (SOX2) in AD rats, while additional studies might be published shortly [513]. The gene discussed is SOX2; the disease is Alzheimer disease.
