About 10% patients with severe disease create auto-antibodies that attack the immune system

People infected by the novel coronavirus can have symptoms that range from mild to deadly. Now, two new analyses suggest that some life-threatening cases can be traced to weak spots in patients' immune systems.

Faulty genes and an autoimmune condition linked to severe COVID-19 in young, healthy people

More than 10 percent of young and healthy people who develop severe COVID-19 have misguided antibodies that attack not the virus, but the immune system itself, new research shows. Another 3.5 percent, at least, carry a specific kind of genetic mutation.

New study may explain why more men than women die from COVID-19

New findings by scientists at the National Institutes of Health and their collaborators help explain why some people with COVID-19 develop severe disease.

HIV drugs cause immune-system changes that can improve resistance to viral infections

Drugs currently used to keep the HIV virus in check also cause immune-system changes that might make humans better able to resist viral infections – but might also cause harmful inflammation, according to a study published today in Cell Reports Medicine.

BU researchers find how SARS-CoV-2 infection may drive deadly lung inflammation

Responding to the COVID-19 pandemic caused by the novel coronavirus, SARS-CoV-2, requires models that can duplicate disease development in humans, identify potential targets and enable drug testing.

Ineffective immune responses may be responsible for COVID-19 mortality rates in men and the elderly

News-Medical speaks to Dr. Nicole Lieberman about her latest research that discovered delayed immune responses may affect COVID-19 mortality rates.

Scientists explain why men are at higher risk from COVID-19

Published in the journal PLOS Biology, the study aimed to provide a better understanding of the mechanisms that drive the varying responses of the infected individuals among different patient demographics, including sex and age.

Seasonal influenza and COVID-19 risk

In a new study published on the preprint server medRxiv, researchers from Laval University and McGill University in Canada reviewed evidence from 18 relevant studies on a possible interaction between influenza vaccines on non-influenza respiratory disease (NIRD).

SARS-CoV-2 Neucleocapside (N) protein is heavily glycosylated

However, the nucleocapsid (N) protein is also extremely abundant and, therefore, a useful target for both vaccine and diagnostic test development. A new study published on the preprint server bioRxiv in August 2020 reveals the structure of this protein, a valuable step in using it for these purposes.

SARS-CoV-2 ORF9c responsible for immune evasion and efficient infection of host

A recent study by researchers at the Sanford Burnham Prebys Medical Discovery Institute and the University of California San Francisco and published on the preprint server bioRxiv in August 2020 shows that a protein encoded by the subgenomic sequence ORF9c of SARS-CoV-2 is responsible for the low antiviral response in infected humans, enabling the successful replication of the virus in the host.

SARS-CoV-2 hijacks antiviral factors to promote infection in human lung cells

Now, a new study published in the preprint server bioRxiv in August 2020 shows that under conditions resembling those in vivo, IFNs may promote efficient viral invasion instead.

JAK inhibitors or type I interferon shown to reduce mortality in COVID-19

Now, a new study by researchers at Yale University and published on the preprint server medRxiv in August 2020 reports that the use of two drug categories, namely, JAK inhibitors and Type I interferons (IFNs), is associated with a dramatic improvement in mortality in COVID-19.

C-type lectin receptors play a role in SARS-CoV-2 infection

A new study published on the preprint server bioRxiv in August 2020 confirms and extends earlier findings showing that a type of sugar-based receptor on innate immune cells promotes the entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into other cells that carry the viral receptor, angiotensin-converting enzyme 2 (ACE2).

Research looks at convalescent plasma use in COVID-19 mouse model

A new study by researchers at the University of Iowa and published on the preprint server bioRxiv in August 2020 reports the utility of a mouse model that recapitulates several aspects of human COVID-19 and can reflect the antiviral efficacy of new drugs as well.

12 Aug 2020

Yale researchers develop new mouse model to study SARS-CoV-2 infection

Researchers at Yale University School of Medicine have developed a new mouse model to study SARS-CoV-2 infection and disease and to accelerate testing of novel treatments and vaccines against the novel coronavirus.

15 young scientists receive Damon Runyon Fellowship Award to pursue cancer research

Grants totaling nearly $3.5 million give early career investigators independence to pursue brave and bold cancer research.

Researchers identify potential anti-viral strategy for SARS-CoV-2 virus

In the case of an infection, the SARS-CoV-2 virus must overcome various defense mechanisms of the human body, including its non-specific or innate immune defense. During this process, infected body cells release messenger substances known as type 1 interferons. These attract natural killer cells, which kill the infected cells.

Researchers identify TLR7 gene that predisposes elderly patients to severe COVID-19

Current observations suggest that the coronavirus SARS-CoV-2 causes severe symptoms mainly in elderly patients with chronic disease.

Study shows interferons do not induce the expression of SARS-CoV-2 cell entry receptor

In a new bioRxiv study, authors identified a isoform of ACE2 (designated as deltaACE2 or dACE2) receptor, shown to be induced in various human cell types.

Experimental therapy slows zika replication and prevents microcephaly in mice

An international group of researchers have discovered that inhibiting AHR (aryl hydrocarbon receptor), a protein with roles in regulating immunity, stem cell maintenance and cellular differentiation, enables the immune system to combat replication of zika virus in the organism far more effectively.
