SNAP25 and Alzheimer disease: The expression of six different microRNAs (miR-181a-5p, miR-361-3p, miR-23a-3p, miR-15b-3p, miR-130a-3p, miR-27b-3p) is associated with a SNAP25 (encoding synaptosome associated protein 25) polymorphism that could affect the neuroplasticity of the brain in patients with AD and had an influence on AD progression (22).
