ALZHEIMER’S DISEASE

Neuronal HSPGs lay a trap for amyloid

Deleting neuronal heparan sulfates in a mouse model of Alzheimer’s disease results in faster Aβ clearance, reduced Aβ aggregation, and less amyloid pathology.

C.-C. Liu, N. Zhao, Y. Yamaguchi, J. R. Cirrito, T. Kanekiyo, D. M. Holtzman, G. Bu, Neuronal heparan sulfates promote amyloid pathology by modulating brain amyloid-β clearance and aggregation in Alzheimer’s disease. Sci. Transl. Med. 8, 332ra44 (2016). [Abstract]

INFLAMMATION

Guarding inflammation

A mutation in pyrin that disrupts regulation leads to autoinflammatory disease.
