“…Dysregulation of miRNA expression profiles has been described in several brain areas and fluids of PD patients, as well as in iPSCs-derived DNs generated from affected patients. Table 2 shows a list of 15 miRNAs (let-7b, miR-34b, miR-124, miR-126, miR-132, miR-133b, miR-144, miR-148b, miR-184, miR-199a, miR-204, miR-218, miR-221, miR-338, miR-425) that were found dysregulated by at least two independent studies in nervous tissues (midbrain, prefrontal cortex, amygdala, laser-micro dissected DNs, or anterior cingulate gyrus) [ 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 ], iPSC-derived DNs [ 119 ] and circulating fluids (CSF, plasma, serum, peripheral blood) [ 119 , 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 , 137 , 138 , 139 , 140 , 141 , 142 , 143 , 144 , 145 , 146 , 147 , 148 ] of PD patients, thus supporting their potential utility as biomarkers and/or therapeutic targets.…”
