Scientists Find Genes Linked to Human Neurological Disorders in Sea Lamprey Genome

Scientists have identified several genes linked to human neurological disorders, such as Alzheimer’s disease, Parkinson’s disease and spinal cord injury, in the sea lamprey. The lamprey has large, identified neurons in its brain and spinal cord, making it an excellent model to study regeneration at the single cell-level.

Genome-Wide Imaging Study Identifies New Gene Associated with Alzheimer’s Plaques

Researchers combined genetic data with neuroimaging in order to identify genes associated with amyloid plaque deposits in Alzheimer's disease patients. The study is believed to be the first genome-wide association study of plaque deposits using a specialized PET scan tracer that binds to amyloid.

Neuronal Activity Induces Tau Release from Healthy Neurons

Researchers discover neuronal activity can stimulate tau release from healthy neurons in the absence of cell death. The study shows treatment of neurons with known biological signaling molecules increases the release of tau into the culture medium.
