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?
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
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.
