Concerning proinflammatory miRNAs, miRNA-144 may have been of high importance in AD by regulation of hBD-2 and SERPINB4—NF-κB activators, while decreased levels of let-7a-5p in AD relate to the overexpression of CCR7 on T-cells and DCs in atopic patients [37,43]. This evidence concerns the gene SERPINB4 and Alzheimer disease.
