Progressive supranuclear palsy (PSP), a mysterious and deadly neurological disorder, usually goes undiagnosed until after a patient dies and an autopsy is performed. But now, UC San Francisco researchers have found a way to identify the condition while patients are still alive.     A study appearing in Neurology on July 3 has found a pattern in the spinal fluid of PSP patients, using a new high-throughput technology that can measure thousands of proteins in a tiny drop of fluid.    Researchers ...

The cerebellum is a region of the brain that helps us refine our movements and learn new motor skills. Patients and mouse models experience many kinds of abnormal movements when their cerebellum is damaged. They can have uncoordinated and unbalanced movements, called ataxia. They can have atypical positioning of body parts or uncontrolled movements because their muscles are working against each other, called dystonia. Or they can have disruptive shaky movements, called tremors. Understanding how changes in a single brain region ...

Twelve years ago, cancer researchers at University of California San Diego identified a molecule that helps cancer cells survive by shuttling damaging inflammatory cells into tumor tissue. In new research, they show that the same molecule does the same thing in lung tissue infected with COVID-19 — and that the molecule can be suppressed with a repurposed cancer drug. The work, published in Science Translational Medicine, represents a new approach to preventing irreversible organ damage in infectious diseases like COVID-19 and methicillin-resistant Staphylococcus aureus (MRSA).  The two key players in this scenario are inflammatory cells called myeloid ...

Many vaccines are only partially effective, have waning efficacy, or do not work well in the very young or the very old.

Dexamethasone is one of the most important drugs in the treatment of severe COVID-19, but patients respond very differently to the therapy. Researchers at the German Center for Neurodegenerative Diseases (DZNE) and Charité – Universitätsmedizin Berlin have now discovered how the cortisone compound influences the impaired inflammatory response and which patients benefit from it. Their method uses so-called single-cell analyses and raises hopes for a precise prediction tool for other therapies and diseases as well. The findings have been published in the scientific journal Cell. It has long been puzzling why certain drugs work so well for some people and fail ...
