MAPT and Alzheimer disease: Growing evidence suggests that some of these miRNAs may be important players in the development of AD by regulating Aβ accumulation (miR‐138,46, 47 miR‐146a48); tau hyperphosphorylation (miR‐138,47 miR21949); synaptic dysfunction (miR‐13846); neuroinflammation (miR‐146a48, 50); and dysfunctional autophagy (miR‐20451, 52).
