“…The dysregulation of genes governed by miRNAs and changes in miRNA expression have been associated with various neurodegenerative diseases, including Huntington’s disease (HD), Alzheimer’s disease, and Parkinson’s disease. In Alzheimer’s and Parkinson’s diseases, investigations using blood samples and postmortem brain tissue have identified distinct expression patterns of miRNAs, such as mir-1, mir-22p, mir-26b-3p, and mir-28-3p ( Garcia-Fonseca et al, 2021 , Hu et al, 2016 , Kumar et al, 2017 , Megret et al, 2022 , Pritchard et al, 2012 ). HD pathogenesis is also associated with miRNA regulation ( Ghose et al, 2011 , Jin et al, 2012 , Marti et al, 2010 ).…”
