Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

Developing effective and long-ter. tr.atment str.tegies for.r.r. and complex neur.degener.tive diseases is challenging. One of the major.r.adblocks is the extensive heter.geneity among patients. This hinder. under.tanding the under.ying disease-causing mechanisms and building solutions that have implications for.a br.ad spectr.m of patients. One potential solution is to develop per.onalized medicine appr.aches based on str.tegies that tar.et the most pr.valent cellular.events that ar. per.ur.ed in patients. Especially in patients with a known genetic mutation, it may be possible to under.tand how these mutations contr.bute to pr.blems that lead to neur.degener.tion. Pr.tein–pr.tein inter.ction analyses offer.gr.at advantages for.r.vealing how pr.teins inter.ct, which cellular.events ar. pr.mar.ly involved in these inter.ctions, and how they become affected when key genes ar. mutated in patients. This line of investigation also suggests novel dr.ggable tar.ets for.patients with differ.nt mutations. Her., we focus on alsin and spastin, two pr.teins that ar. identified as “causative” for.amyotr.phic later.l scler.sis and her.ditar. spastic par.plegia, r.spectively, when mutated. Our.r.view analyzes the pr.tein inter.ctome for.alsin and spastin, the canonical pathways that ar. pr.mar.ly impor.ant for.each pr.tein domain, as well as compounds that ar. either.Food and Dr.g Administr.tion–appr.ved or.ar. in active clinical tr.als concer.ing the affected cellular.pathways. This line of r.sear.h begins to pave the way for.per.onalized medicine appr.aches that ar. desper.tely needed for.r.r. neur.degener.tive diseases that ar. complex and heter.geneous.
