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.

BPA May Affect the Developing Brain by Disrupting Gene Regulation

New research suggests environmental exposure to bisphenol A (BPA), a chemical commonly found in plastics and resins, could suppress a gene critical to nerve cell function and the development of the central nervous system. Exposure to BPA could predispose humans to a number of neurodevelopmental and other health disorders.

Where Does Our Head Come From?

New research has shed light on the evolutionary origin of the head.Researchers showed that in a simple, brainless sea anemone, the same genes that control head development in higher animals regulate the development of the front end of the swimming larvae.

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.

Researchers Uncover New Findings on Genetic Risks of Behçet’s Disease

Researchers identify regions of genes linked to Behçet’s disease, a poorly understood condition that causes painful and serious symptoms, including ulcers and brain inflammation. The study identified novel gene variants in the inflammatory disorder and uncovered data that could apply to studies of other diseases.

Low Protein Diet Slows Alzheimer’s in Mice

Researchers discovered that a low protein diet can slow the progression of Alzheimer's disease in mice. By cycling between a normal and protein restricted diet, researchers noted both improvement in memory and a slowing in the advancement of the disease.

Scientists Turn Off the Ability to Feel Cold

Researchers have isolated chills at a cellular level, identifying the sensory network of neurons in the skin that relays the sensation of cold. By better understanding the specific ways in which we feel sensations, scientists hope to one day develop better pain treatments without knocking out all ability to feel for suffering patients.
