An emerging spectrum of therapeutic targets for Alzheimer's disease.

Development of effective preventative and therapeutic measures for Alzheimer's disease has been unsuccessful because of the long and subtly symptomatic preclinical period, difficulties obtaining tissue and biochemical data from living patients, and the many complex underlying pathogenic processes. Recent applications of sensitive specific bioimaging techniques, analyses of RNAs and proteins of neural cell-derived extracellular vesicles in blood, and sophisticated genetic procedures in cellular and rodent models have yielded hopeful new therapeutic targets. These newer targets are described here in relation to their neural cellular location, potential genetic modifications and possible pharmacological approaches.
