Intro
2
The lysosome is an example of the optimized subcellular biochemistry: it degrades macromolecules to recycle their nutrient content
3
Understanding these functions might be key for understanding a wide range of human disease
4
Subcellular metabolism as a new approach to study organelle dysfunction in human disease
5
Untargeted metabolomics reveals the accumulation of Glycerophosphodiesters (GPDs) in CLN3 deficient lysosomes
6
How does CLN3 deficiency lead to neuronal cell death in Batten disease?
7
Decreased contribution of GPC-derived choline to lipid biosynthesis in CLN3 KO-neurons
8
Lysosomal choline metabolism is essential for brain homeostasis
9
Choline: an essential metabolite in physiology
10
What are the principal sources of choline?
11
Endolysosomal CRISPR-Cas9 screen to identify lysosomal proteins important for surviving choline deprivation
12
Phosphocholine and choline are not accumulating in SPNS1- deficient lysosomes
13
SPNS1-deficient lysosomes accumulate lysophosphocholine (LPC) and lysophosphoethanolamine (LPE)
14
LPCs generated in lysosomes are trapped in SPNS1-deficient lysosomes
15
SPNS1 is a lysosomal lysophospholipid transporter
16
A novel lysosomal phospholipid salvage pathway

Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only! Grab it Watch a 42-minute research lecture from the Inaugural Brain Resilience Symposium exploring lysosome function and its critical role in brain health and disease. Delve into groundbreaking research on subcellular metabolism and organelle dysfunction, with particular focus on Batten disease and CLN3 deficiency. Learn about the accumulation of Glycerophosphodiesters in lysosomes, the essential role of choline in brain homeostasis, and discover a novel lysosomal phospholipid salvage pathway. Examine findings from endolysosomal CRISPR-Cas9 screening that identifies crucial lysosomal proteins, and understand the implications of SPNS1 deficiency on lysophospholipid transport. Presented by Monther Abu-Remaileh, this talk provides deep insights into the optimization of subcellular biochemistry and its potential impact on treating various human diseases.
