Research Team Discovers Molecular Processes in Kidney Cells That Attract and Feed COVID-19

What about the kidneys make them a hotspot for COVID-19's cytokine storm? A research team says it's the presence of a protein found on specialized renal transport ...

Coronavirus Mutations Show Early Safety Measures and Restrictions Limited Viral Spread

Scientists analyzed genomic information from over 6,000 samples of SARS-CoV-2, the coronavirus behind the COVID-19 pandemic. Results show that early measures in states such as California and ...

A Promising Discovery Could Lead to Better Treatment for Hepatitis C

Virologists have identified a critical role played by a cellular protein in the progression of Hepatitis C virus infection, paving the way for more effective treatment. No vaccine currently exists ...

COVID-19 Infection May Be Part of a 'Perfect Storm' for Parkinson's Disease

Can COVID-19 infection increase the risk of developing Parkinson's disease? That's the question posed by a new commentary that explores three known case studies of people developing ...

How Herpes Infection May Impair Human Fetal Brain Development

Three cell-based models shed light on how herpes simplex virus type 1 (HSV-1) infection, which can spread to the fetal brain during pregnancy, may contribute to various neurodevelopmental ...

Do Asymptomatic Kids With COVID-19 Carry Less Virus?

A new study from nine children's hospitals finds that most asymptomatic children who tested positive for COVID-19 had relatively low levels of the virus compared to symptomatic children. The ...

Details 211Ʊ Broadly Neutralizing Antibodies Provide Insights for Universal Flu Vaccine

New research from an immunology team may shed light on the challenges of developing a universal flu vaccine that would provide long-lasting and broad protection against influenza ...

Immune Response the Probable Underlying Cause of Neural Damage in COVID-19

A new study shows that it is probably the immune response to, rather than the virus in itself, that causes sudden confusion and other symptoms from the nervous system in some patients with ...

Multiple Sclerosis as the Flip Side of Immune Fitness

211Ʊ half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study has now shown how this genetic predisposition contributes to the development of the autoimmune disease ...

Tracking the SARS-CoV-2 Virus With Genome Sequencing

A new study shows how next generation genetic sequencing can track mutations in the SARS-CoV-2 virus, which can in effect help with transmission tracing, diagnostic testing accuracy and vaccine ...

Hydroxychloroquine Does Not Prevent COVID-19 in Health Care Workers, Trial Shows

Researchers found that taking hydroxychloroquine once or twice weekly did not prevent the development of COVID-19 in health care workers better than the ...

Observed COVID-19 Variability May Have Underlying Molecular Sources

People have different susceptibilities to SARS-CoV-2, the virus behind the COVID-19 pandemic, and develop varying degrees of fever, fatigue, and breathing problems -- common symptoms of the illness. ...

Genome Archeologists Discover Path to Activate Immune Response Against Cancer

Ancient embedded elements in our DNA from generations past can activate a powerful immune response to kill cancer cells like an ...

Hidden States of the COVID-19 Spike Protein

Computer modeling of the COVID-19 virus on supercomputers showed that the spike protein visits an intermediate state before it can dock to the receptor protein on the host cell membrane. This ...

Evidence Review Confirms CDC Guidance 211Ʊ Infectivity of Novel Coronavirus

A new review of dozens of studies suggests that people may shed virus for prolonged periods, but those with mild or no symptoms may be infectious for no more than about 10 days. People who are ...
