Study demonstrates that intra-host SARS-CoV-2 variants with reduced infectivity are developed during infection

A new paper discusses the appearance of quasi-species in a single host with prolonged infection, with different rates of infectivity and sensitivity to neutralization by antibodies elicited by the Pfizer vaccine or those present in convalescent plasma.

Study investigates whether immune responses to BNT162b2 vaccine differ in subjects with and without prior SARS-CoV-2 infection

A new paper published in the journal JCI Insight reports on the differential levels of immunity achieved in those with and without a history of prior infection with the virus following one and two doses of the earliest vaccines to be approved for emergency use.

Study identifies cellular receptors for alphaviruses shared across mosquitoes, humans, and animals

A new study led by researchers at Harvard Medical School has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.

Researchers engineer enucleated cells to deliver therapeutics precisely to diseased tissues

Researchers at University of California San Diego School of Medicine and Moores Cancer Center at UC San Diego Health report successfully removing the nucleus out of a type of ubiquitous cell, known as enucleation, then using the genetically engineered cell as a unique cargo-carrier to deliver therapeutics precisely to diseased tissues.

Pathogens turn off mitochondrial defense by hijacking a normal cellular response to stress

Mitochondria are known as energy suppliers for our cells, but they also play an important role in the defense against pathogens. They can initiate immune responses, and deprive pathogens of the nutrients they need to grow.

Protein biomarkers in urine could be used to diagnose concussion and monitor recovery

Concussion can be frustratingly hard to diagnose and track. The injury doesn't show up on routine brain scans, and there is no definitive diagnostic test. It's usually diagnosed based on symptoms, and, in athletes, comparison with baseline testing if it was done. But concussion symptoms are non-specific, unreliable, and easily influenced by emotions.

Mutations in SARS-CoV-2 Omicron variant promote cell binding

Researchers in Germany, based on their recent study published in the journal ChemBioChem, have proposed that the elevated occurrence of positively charged amino acids in specific domains of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant spike protein improves viral binding to cellular negatively charged receptors aiding in enhanced infectiousness.

Monitoring rodents for SARS-CoV-2 and other coronaviruses, Hong Kong

A new study published in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal has hypothesized that locations with positive SARS-CoV-2 in sewage could be used as potential surveillance targets to analyze if pestiferous urban rodents shed SARS-CoV-2 into the environment.

Topical antiseptic Acriflavine inhibits SARS-CoV-2 and other betacoronaviruses

A new study, published in the journal Cell Chemical Biology, has reported the discovery of acriflavine (ACF), an effective inhibitor of SARS-CoV-2. This drug is a mixture of trypaflavines (3,6-diamino-10-methylacridinium chloride and 3,6-diamino-3-methylacridinium chloride) and proflavine (3,6-diaminoacridine).

Cannabidiol may improve innate immune response against SARS-CoV-2

A recent study shows evidence that cannabidiol, an important active ingredient in the Cannabis sativa plant, can augment the antiviral innate immune response and prophylactically prime the innate antiviral response of cells – enabling in turn improved response against viruses such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

UMass Amherst professor receives $2 million NIH MIRA grant for trailblazing research

Jianhan Chen, a University of Massachusetts Amherst chemistry and biochemistry and molecular biology professor, has received a five-year, $2 million National Institutes of Health (NIH) grant to support research in his computational biophysics lab aimed at better understanding the role of intrinsically disordered proteins (IDPs) in biology and human disease.

Even mild SARS-CoV-2 respiratory-only infection can cause long-term neurologic damage

A new bioRxiv* preprint study led by Michelle Monje of Stanford University in California finds that a mild COVID-19 infection can produce long-term neurological damage. Persistent cognitive complications are one of many symptoms of long COVID, and the latest results suggest the severity of COVID-19 induced brain fog is similar to cancer’s “chemobrain.”

UV-C light prevents airborne transmission of SARS-CoV-2

Researchers demonstrate that ultraviolet light-C (UV-C) effectively prevents airborne transmission of SARS-CoV-2.

Research shows fewer deaths related to COVID-19 in Cape Town during fourth wave

Researchers observe changes in COVID-19-related deaths during the fourth wave of the COVID-19 pandemic in South Africa.

Omicron variant spike protein shows significantly weaker membrane fusion activity than other variants

New research suggests that the SARS-CoV-2 Omicron spike protein requires significantly higher levels of ACE2 for efficient membrane fusion, lagging behind other variants.

Synthetic antibody demonstrates Omicron detection along with all other variants of concern

MIP Diagnostics Ltd. has today announced that its synthetic SARS-CoV-2 antibody (COVID-19 nanoMIPTM) can detect the Omicron variant as well as previously proven Alpha, Beta, Delta and Gamma variants of the COVID-19 virus.

Research could advance the understanding of links between heart disease and dementia

Heart disease can directly cause brain dysfunction early on which could lead to dementia and can treble the amount of an Alzheimer's protein in the brain, say scientists.

Study advances the understanding of lymphatic vessels serving the heart

Scientists at the UNC School of Medicine led a study to advance the understanding of lymphatic vessels, which transport lymph, a clear fluid containing important molecules, immune cells and fluid, away from organs and tissues and back to the bloodstream.

Insignificant homology of SARS-CoV-2 spike sequences to myocarditis-associated antigens

Researchers determine whether sequences within SARS-CoV-2 could lead to an immune response to autoantigens associated with autoimmune myocarditis.
