Yale researchers develop RNA-based therapy that clears SARS-CoV-2 from mice

Researchers at Yale School of Medicine have discovered that an RNA molecule that stimulates the body’s early antiviral defense system can protect mice from a range of emerging SARS-CoV-2 variants. The study, published today in the Journal of Experimental Medicine (JEM), could lead to new treatments for COVID-19 in immunocompromised patients, as well as providing an inexpensive therapeutic option for developing countries that currently lack access to vaccines.

Newly Approved Lupus Drug Based on Discoveries Made in HSS Lab

The US Food and Drug Administration approved the drug anifrolumab (Saphnelo) on August 2, 2021 for the treatment of adult patients with moderate to severe systemic lupus erythematosus (SLE) who are receiving standard therapy. Much of the groundwork for the development of this drug was done in laboratories at Hospital for Special Surgery (HSS) in the early 2000s.

Peginterferon-lambda shows strong antiviral action to accelerate clearance of COVID-19

A clinical study led by Dr. Jordan Feld, a liver specialist at Toronto Centre for Liver Disease, University Health Network (UHN), showed an experimental antiviral drug can significantly speed up recovery for COVID-19 outpatients – patients who do not need to be hospitalized. This could become an important intervention to treat infected patients and help curb community spread, while COVID-19 vaccines are rolled out this year.

Some Severe COVID-19 Cases Linked to Genetic Mutations or Antibodies that Attack the Body

Two new studies offer an explanation for why COVID-19 cases can be so variable. A subset of patients has mutations in key immunity genes; other patients have auto-antibodies that target the same components of the immune system. Both circumstances could contribute to severe forms of the disease.

Researchers develop new mouse model for SARS-CoV-2

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. The study, published today in the Journal of Experimental Medicine (JEM), also suggests that, rather than protecting the lungs, key antiviral signaling proteins may actually cause much of the tissue damage associated with COVID-19.
