Deviant lysosomal Ca(2+) signalling in neurodegeneration. An introduction

Abstract

Lysosomes are key acidic Ca(2+) stores. The principle Ca(2+)-permeable channels of the lysosome are TRP mucolipins (TRPMLs) and NAADP-regulated two-pore channels (TPCs). Recent studies, reviewed in this collection, have linked numerous neurodegenerative diseases to both gain and loss of function of TRPMLs/TPCs, as well as to defects in acidic Ca(2+) store content. These diseases span rare lysosomal storage disorders such as Mucolipidosis Type IV and Niemann-Pick disease, type C, through to more common ones such as Alzheimer and Parkinson disease. Cellular phenotypes, underpinned by endo-lysosomal trafficking defects, are reversed by chemical or molecular targeting of TRPMLs and TPCs. Lysosomal Ca(2+) channels therefore emerge as potential druggable targets in combatting neurodegeneration.

Alzheimer's Disease: Endosomes

Dysfunctional endosomal trafficking may be associated with Alzheimer’s disease (AD) pathology. Targeting the endosome may advance treatment options for AD. Here is the latest research on endosomes and AD.
