COVID-19 virus disrupts gut bacteria, increasing secondary infection risk
New research, led by New York University Grossman School of Medicine researchers, shows that SARS-CoV-2 infection reduces bacterial diversity in a patient's gut, creating opportunities for dangerous microbes to thrive. Read More
COVID-19 nasal vaccine bolsters immune response, drops transmission
Yale University scientists have concocted a new nasal vaccine that strengthens immune responses to COVID-19 in previously vaccinated animals and reduces viral transmission, which may help prevent breakthrough infections of vaccinated individuals. Read More
Research reveals mechanisms for SARS-CoV-2 infection in macrophages
Boston University researchers have identified a receptor that contributes to hyper-inflammatory responses to SARS-CoV-2 infection -- a finding that may potentially alleviate COVID-19 disease severity. Read More
Banana protein yields potential SARS-CoV-2 therapy
New research finds that a banana protein-derived antiviral is effective against SARS-CoV-2, as well as all known coronaviruses and influenza. Read More
New drug turns COVID-19 virus against itself in animal models
A Scripps Research team showed that NMT5, a variation of a previously approved drug, can cause the COVID-19 virus to block infection in animals and bring about its own demise. Read More
SARS-CoV-2 mimics could make COVID-19 vaccine research safer, quicker
Viruslike particles, molecular mimics that look and act like SARS-CoV-2 without being infectious, are providing new tools against COVID-19 -- the disease caused by the virus. Read More
Mount Sinai scientists unlock secrets of key SARS-CoV-2 enzyme
Mount Sinai researchers have produced a high-resolution crystal structure of an enzyme that is essential to the survival of SARS-CoV-2. The finding could lead to more antivirals to combat current and future coronaviruses, they added. Read More
Antiviral therapy blocks COVID-19 transmission in hamsters: study
Researchers at Gladstone Institutes have shown that a new single-dose intranasal, antiviral treatment for SARS-CoV-2 infection decreases viral shedding and limits transmission of the virus in hamsters. Read More
Harvard’s Wyss Institute spins out protein detection technology to create Spear Bio
The Wyss Institute for Biologically Inspired Engineering at Harvard University has licensed technology for detecting proteins in small patient samples to a newly formed startup. Read More
Key vulnerability discovered across all major SARS-CoV-2 variants
Researchers at the University of British Columbia have discovered a “weak spot” across all major variants of the SARS-CoV-2 virus, including the recently emerged BA.1 and BA.2 omicron subvariants, using cryo-electron microscopy to reveal the atomic-level structure of the vulnerability on the spike protein.
