MicroRNAs in the Neural Retina Table 2 Differentially expressed microRNAs in retinal cell types.
MicroRNA Regulation/function Retinal cell type Refs miR-204, miR-211 Upregulated RPE [48 ] miR-23a Upregulated (in healthy cells) Downregulated (in AMD) RPE [49 ] miR-183/96/182 Downregulated in dark Upregulated in light Photoreceptors and interneurons of the inner nuclear layer [36 ] miR-29b Upregulated after streptozotocin (STZ) injection; upregulation protects against apoptosis RGCs and cells of the INL [47 ] mir-133b Overexpression suppresses maturation and function of dopaminergic amacrine cells Dopaminergic amacrine cells [46 ] mir-124 Abundantly expressed in differentiated neurons
All retinal cell layers, but is not detected in the RPE [45 ]
miR-155*, miR-124. Resting microglia : low expression of miR-155 and high expression of miR-124 Activation phenotype (M1) : downregulation of miR-124, upregulation of miR-155 Activation phenotype (M2) : upregulation of miR-124, downregulation of miR-155Microglia [52 ]
Expression of these miRNAs has been reported for microglia of the brain.
