abstract = {Clinical and genetic research links altered cholesterol
metabolism with ALS development and progression, yet
pinpointing specific pathomechanisms remain challenging. We
investigated how cholesterol dysmetabolism interacts with
protein aggregation, demyelination, and neuronal loss in
ALS. Bulk RNAseq transcriptomics showed decreased
cholesterol biosynthesis and increased cholesterol export in
ALS mouse models (GA-Nes, GA-Camk2a GA-CFP, rNLS8) and
patient samples (spinal cord), suggesting an adaptive
response to cholesterol overload. Consequently, we assessed
the efficacy of the cholesterol-binding drug
2-hydroxypropyl-β-cyclodextrin (CD) in a fast-progressing
C9orf72 ALS mouse model with extensive poly-GA expression
and myelination deficits. CD treatment normalized
cholesteryl ester levels, lowered neurofilament light chain
levels, and prolonged lifespan in female but not male GA-Nes
mice, without impacting poly-GA aggregates. Single nucleus
transcriptomics indicated that CD primarily affected
oligodendrocytes, significantly restored myelin gene
expression, increased density of myelinated axons, inhibited
the disease-associated oligodendrocyte response, and
downregulated the lipid-associated genes Plin4 and ApoD.
These results suggest that reducing excess free cholesterol
in the CNS could be a viable ALS treatment strategy.},
