Integrative genetic analysis illuminates ALS heritability and identifies risk genes.

Amyotrophic lateral sclerosis (ALS) has substantial heritability, in part shared with fronto-temporal dementia (FTD). We show that ALS heritability is enriched in splicing variants and in binding sites of 6 RNA-binding proteins including TDP-43 and FUS. A transcriptome wide association study (TWAS) identified 6 loci associated with ALS, including in NUP50 encoding for the nucleopore basket protein NUP50.

Functionalized nanogel for treating activated astrocytes in spinal cord injury.

Astrogliosis has a unique reaction during spinal cord damage, with helpful or adverse impacts on recovery. There is consequently a pressing need for treatment to target activated astrocytes and their unsafe response after injury to ensure some preservative effect during the progressive damage. We specifically developed and characterized a functionalized nanogel-based nanovector in vitro and in vivo, demonstrating its selectivity towards astrocytes, and limited uptake by macrophages when functionalized with both NH and Cy5 groups.
