When Proteins Go Astray: Uncharted Territory in Adult-Onset Neuronal Ceroid Lipofuscinosis

Published on April 9, 2022

Imagine a bunch of unruly proteins going off the rails and causing chaos in your brain. That’s kind of what happens in adult-onset neuronal ceroid lipofuscinosis (ANCL), a group of inherited neurodegenerative diseases. Instead of staying where they’re supposed to, these troublesome proteins form clumps and accumulate inside lysosomes, which are like tiny garbage disposals in your cells. It’s like a party gone wrong, with lipids, proteins, and metal materials mingling together and causing trouble. In this particular case, a young Chinese woman with ANCL has a brand-new DNAJC5 gene mutation called C128Y, which messes up something called protein palmitoylation and triggers the formation of lipofuscin deposits. By understanding these molecular hiccups, scientists can develop targeted treatments to clean up the party mess in our cells and potentially slow down the progression of ANCL. So grab your lab coat and delve into the fascinating research behind this promising breakthrough!

Neuronal ceroid lipofuscinosis (NCL) is composed of a group of inherited neurodegenerative diseases, with the hallmark of lipofuscin deposit (a mixture of lipids and proteins with metal materials) inside the lysosomal lumen, which typically emits auto-fluorescence. Adult-onset NCL (ANCL) has been reported to be associated with a mutation in the DNAJC5 gene, including L115R, L116Δ, and the recently identified C124_C133dup mutation. In this study, we reported a novel C128Y mutation in a young Chinese female with ANCL, and this novel mutation caused abnormal palmitoylation and triggered lipofuscin deposits.
