Mitochondria-lysosome contacts are recently identified sites for mediating crosstalk between both organelles, but their role in normal and diseased human neurons remains unknown. We used super-resolution and live-cell microscopy in human iPSC-derived neurons to demonstrate that mitochondria-lysosome contacts can dynamically form in the soma, axons, and dendrites of human neurons,...
Inter-organelle contact sites have become increasingly appreciated as important regulators of cellular homeostasis, and disruption of inter-organelle contact site dynamics and function has been observed in various pathologies. Recently, inter-organelle contact sites between mitochondria and lysosomes were discovered, offering a new mechanism by which these two organelles may directly interact,...
Mitochondrial complex I is the primary entry point for electrons into the mitochondrial electron transport chain that is composed of 45 individual protein subunits that are encoded in both the nuclear and mitochondrial genomes. Mitochondrial complex I sits at an important nexus in the essential bioenergetic, biosynthetic, and signaling functions...
Frontotemporal Dementia (FTD) and Amyotrophic Lateral Sclerosis (ALS) are two devastating neurodegenerative diseases that affect 100,000s of people globally. They have a severe adverse impact on society, yet there are currently no early diagnostic tools or disease-modifying therapies available. Despite their clinical heterogeneity, evidence points to these diseases being on...
