As RNA Therapies Come of Age, Efficacy Remains Weak At AAN, Sights Set on Antisense Therapies for Diseases of the Brain New Alzheimer’s and Parkinson’s Immunotherapy Data at AAN Will RNA molecules that bump up or tamp down gene expression live up to their ...
A fleet of patient-derived neurons show that while an APP mutation shifts where γ-secretase takes its first bite, PS1 mutations blunt the enzyme’s second cut. Eventually, all mutations drive up the Aβ42:40 ratio.
Many genes that increase risk for late-onset AD are expressed in microglia, and researchers are going cell by cell to unravel the pathways involved in the immune response to amyloid and tau.
At SfN and in new papers, scientists describe how synapses crater under the combined onslaught of Aβ and tau. They also link gene-expression signatures to the selective vulnerability of excitatory neurons to tau pathology.
Aggregates that form inside, or just pass through, oligodendrocytes take on the properties of the virulent strain that gives rise to multiple system atrophy.
