<b>Objective: </b> Migraine carries an increased risk for cardiovascular and cerebrovascular diseases that cannot be explained by traditional cardiovascular risk factors. The circulating endothelial progenitor cell (EPC) number is a surrogate biologic marker of vascular function, and diminished EPC counts are associated with higher cardiovascular risk. We investigated whether abnormalities in EPC levels and functions are present in migraine patients. <b>Methods: </b> Consecutive headache patient

Huntington's disease (HD) is a hereditary neurodegenerative disorder caused by the aggregation of mutant Huntingtin (mHtt). Adipose-derived stem cells (ASCs) have a potential for use in the treatment of incurable disorders, including HD. ASCs secrete various neurotrophic factors and microvesicles, and modulate hostile microenvironments affected by disease through paracrine mechanisms. Exosomes are small vesicles that transport nucleic acid and protein between cells. Here, we investigated the the

Stem cell therapy is a promising treatment for incurable disorders including Huntington's disease (HD). Adipose-derived stem cell (ASC) is an easily available source of stem cells. Since ASCs can be differentiated into nervous stem cells, it has clinically feasible potential for neurodegenerative disease. In addition, ASCs secrete various anti-apoptotic growth factors, which improve the symptoms of disease from transplanted ASCs. Thus, cell-free extracts of ASCs (ASCs-E) could be a potential can

Huntington's disease (HD) is one of the most devastating genetic neurodegenerative disorders with no effective medical therapy. β-Lapachone (βL) is a natural compound obtained from the bark of the Lapacho tree and has been reported to have beneficial effects on various diseases. Sirt1 is a deacetylase of the sirtuin family and deacetylates proteins including the peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) which is associated with mitochondrial respiration and bi

We found that the overall pathology of HD could be improved by the shared blood circulation through heterochronic parabiosis, furthermore, we demonstrated that the exosomes could be messengers for transferring positive factors, showing the potential of exosomes from young blood for the amelioration of HD.

Huntington's disease (HD) is a genetic neurodegenerative disorder caused by abnormal expansion of CAG in the huntingtin gene. In R6/2 HD transgenic mice, human adipose-derived stem cells (ASCs) can slow disease progression via secretion of multiple paracrine growth factors. In order to prompt autologous ASCs transplantation in HD, we isolated ASCs from subcutaneous adipose tissues from a HD patient and a normal volunteer. ASCs were grown in two different types of stem cell culture media, EGM-2MV

Gene therapy is a potential therapeutic strategy for treating hereditary movement disorders, including hereditary ataxia, dystonia, Huntington's disease, and Parkinson's disease. Genome editing is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome using modified nucleases. Recently, clustered regularly interspaced short palindromic repeat/CRISPR associated protein 9 (CRISPR/Cas9) has been used as an essential tool in biotechnology. Cas9 is an RNA-guided DNA
