Unraveling one of prion disease's deadly secrets

A molecular biologist at the University of Massachusetts Amherst who has for decades studied the nightmarish group of fatal diseases caused by prions—chronic wasting disease in deer, mad cow in cattle and its human analog—credits ...

How do our cells respond to stress?

Cells are often exposed to stressful conditions that can be life threatening, such as high temperatures or toxins. Fortunately, our cells are masters of stress management with a powerful response program: they cease to grow, ...

Network of protein-RNA interaction guides phase separation

St. Jude Children's Research Hospital investigators are studying the details of how phase separation leads to the formation of RNA granules, assemblies of protein and RNA that are not bound by a membrane. Their findings show ...

Hero proteins are here to save other proteins

Researchers at the University of Tokyo have discovered a new group of proteins, remarkable for their unusual shape and abilities to protect against protein clumps associated with neurodegenerative diseases in lab experiments. ...

The unchanging viscosity of cells

The only thing that appears to be unchanging in living cells is that they are constantly changing. However, scientists from the IPC PAS have managed to show that there is a certain parameter that does not change. It's their ...

A fundamental discovery about how gene activity is regulated

Researchers at Johns Hopkins Bloomberg School of Public Health have discovered a fundamental mechanism that regulates gene activity in cells. The newly discovered mechanism targets RNA, or ribonucleic acid, a close cousin ...

Researchers say may have found cause of mad cow disease

Researchers said Wednesday they believe they may have found the cause of mad cow disease, while stressing the need to maintain precautionary measures to avoid a potential re-emergence of the illness.

Neurodegenerative disease

Neurodegenerative disease (Greek νέυρο-, néuro-, "nerval" and Latin dēgenerāre, "to decline" or "to worsen") is a condition in which cells of the brain and spinal cord are lost. The brain and spinal cord are composed of neurons that do different functions such as controlling movements, processing sensory information, and making decisions. Cells of the brain and spinal cord are not readily regenerated en masse, so excessive damage can be devastating. Neurodegenerative diseases result from deterioration of neurons or their myelin sheath which over time will lead to dysfunction and disabilities resulting from this.

Some sources limit the term "degenerative" to conditions primarily affecting gray matter that are not associated with a obvious inciting event.
