Neurodegeneration News and Research

RSS

Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.

New Research Reveals Mitochondrial Guardians Linked to Parkinson’s and ALS

Scientists at Johns Hopkins Medicine say they have discovered how a group of proteins linked to Parkinson's disease and amyotrophic lateral sclerosis act as "guardians" of mitochondria, small organelles, or subunits, within a cell that make and store energy and are found in almost all plants and animals.

New Study Challenges Traditional View of Axon Shape and Function

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell – and propose a new model for understanding how information is transmitted in the brain.

Integrating Multiple Scales to Understand Brain Function

A long-standing goal of neuroscience is to understand how molecules and cellular structures on a microscale give rise to communication between brain regions at the macroscale. A study published in Nature Neuroscience now identifies, for the first time, hundreds of brain proteins that explain inter-individual differences in functional connectivity and structural covariation in the human brain.

Structural Insights into Bacteriophages Open Doors for New Therapeutics

The viruses that infect bacteria are the most abundant biological entities on the planet. For example, a recent simple study of 92 showerheads and 36 toothbrushes from American bathrooms found more than 600 types of bacterial viruses, commonly called bacteriophages or phages.

A New Method to Correct Misplaced Proteins in Cells

Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally stands watch over DNA replicating in the nucleus is sent far from the DNA it is meant to monitor, allowing cancers to grow.
