At the at Tau2020 conference, scientists show high-resolution cryo-EM of α-synuclein. Two different types of fibril are composed of asymmetric protofibril units.
Centenarians who scored high on the MMSE stayed cognitively and physically active over the next two years, even if they carried genetic risk factors for Alzheimer’s. What protects these lucky few?
By engaging scientists studying every tau-based disorder, a new conference aimed to foster collaborations and research directions.
Tau2020: Meeting for Tauopathies Debuts Genetic Variants Behold the First Human α-Synuclein CryoEM Fibril Structure New at Tau2020: PET Detects First Traces of Tangles in Rhinal Cortex Primary Tauopathies Get New PET Ligands Tau Receptor Identified on ...
At HAI 2020, scientists more precisely quantified the relationship between plaques, tangles, and cognitive decline.
Two epigenetic proteins accelerated age-related behavioral decline in worms and in mice, at least partly by dampening mitochondrial function. Orthologs in the human brain ramped up with aging and with AD progression.
Amyloid and tau PET are helping scientists pinpoint the underlying cause of specific AD symptoms. Perhaps imaging of certain brain regions will help predict an individual’s progression.
At the HAI 2020 conference, the tracers PI-2620 and APN-1607 appeared to bind frontotemporal dementia tau. MK-6240 looked highly sensitive. And JNJ-067 and SNFT-1 are two new kids in town.
Vision improved in some retinitis pigmentosa patients in a Phase 1 trial.
Two studies reveal new aspects of the neurovascular physiology that regulate the flow of oxygenated blood into the brain’s arterioles and capillaries in response to neuronal stimulation.
The protease suppresses Aβ in Down’s syndrome organoids.
Post-translational modifications differ from those in AD tau fibrils, and may dictate tau strains.
The creation of long-term memories requires a continual supply of myelin provided by newly formed oligodendrocytes. Alas, the generation of fresh oligodendrocytes diminishes with age, along with memory.
FDA approves adding safety and efficacy data from an Alzheimer’s trial to the drug’s label.
DIAN, Roche, Lilly disclose that neither gantenerumab nor solanezumab slowed cognitive decline in the first-pass comparison of drug and placebo groups. Analyses are ongoing; dose may have been too low.
