Under diabetic conditions, SERP1 binds secretase subunit, cranking up cleavage of APP but not Notch. The finding offers a mechanistic link between diabetes and Alzheimer’s.
The slowdown of proteasomes stymied TDP-43’s entry into the nucleus and promoted its aggregation in the cytoplasm.
In a conditional mouse knockout, lack of neuronal BIN1 slowed excitatory signaling, leading to spatial memory problems. Could this play a role in Alzheimer’s?
In the human brain, alpha waves fell out of sync, while delta-theta waves swelled in concert with amyloid plaques, neurofibrillary tangles. Alpha modulation correlated with cognitive decline.
Different forms of p-tau in cerebrospinal fluid reflect worsening plaque load, metabolism, and atrophy in the brain. They could help stage Alzheimer’s disease.
A survey conducted by the Alzheimer’s Association finds that three-quarters of these physicians had little to no residency training in dementia care.
In motor neurons of TMEM106b knockout mice, swollen vacuoles piled up in axons near the soma, rendering the mice wobbly and slow to react. The finding contradicts prior reports.
The monoclonal antibody activated TREM2 signaling on mouse microglia. It supported their survival and stimulated their clearance of amyloid plaques.
At Tau2020 conference, scientists implicate LDL receptor-related protein 1 in cell-to-cell transmission.
Autopsy data confirm that current tau PET tracers are unsuitable for some primary tauopathies. CryoEM structures help researchers find new ligands for tau and α-synuclein.
Not sure where that is? You are not alone. It is a tiny spot deep behind the nose, newly defined by the PET signal of early neurofibrillary tangle deposition. It also prompted a tau-staging scheme.
At the at Tau2020 conference, scientists show high-resolution cryoEM 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 Cel
