New imaging technique helps reveal the best antibodies for COVID-19 detection

Vaccines are turning the tide of the pandemic, but the risk of infection is still present in some situations. If you want to visit a friend, get on a plane, or go see a movie, there is no highly accurate, instant test that can tell you right then and there whether or not you have a SARS-CoV-2 infection.

A possible human-to-canine transmission of SARS-CoV-2

Now, researchers at the U.S. Centers for Disease Control and Prevention (CDC) identified a case of human to animal transmission when SARS-CoV-2 was detected in a healthy poodle dog living with four family members who had COVID-19.

Researchers investigate immune molecule that helps protect transplanted kidneys

Looking to improve organ transplant success, researchers are working to learn more about how an immune molecule, which also protects a fetus, helps protect some transplanted kidneys, and to develop a synthetic version of that molecule that could help more patients.

Stabilizing mutations in SARS-CoV-2 immunogens improve vaccine design

Researchers in the United States have developed stabilized immunogens presenting the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may improve the scalability of RBD-based coronavirus vaccines.

Milder COVID-19 in children may be due to higher memory B cells responses to SARS-CoV-2

A new research paper published in the journal Science explores the differences in coronavirus-specific B memory cell repertoires in children versus adults, as well as the functional importance of this discovery.

Breastfeeding safe and beneficial in SARS-CoV-2 infection

\With the onset of the coronavirus disease 2019 (COVID-19) pandemic, hundreds of millions of people became infected worldwide, including thousands of pregnant women near term. The question of vertical transmission to the infant via the placenta or breast milk was very real, leading to a near-total ban on breastfeeding in this group.

ACROBiosystems makes donations to BEI Resources, accelerating the process of attacking SARS-CoV-2 variants globally

Multiple SARS-CoV-2 variants are emerging and circulating globally; the battle against COVID-19 pandemic is still challenging. Recently, ACROBiosystems donated SARS-CoV-2 mutant proteins to BEI Resources, a NIAID funded bioresource program, joining in the collective effort in attacking SARS-CoV-2 variants globally.

A SARS-CoV-2 neutralizing antibody with extensive spike binding coverage

In a recently published research paper in the journal Nature Communications, a team of scientists from China has described the antiviral efficacy of a novel anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody isolated from recovered coronavirus disease 2019 (COVID-19) patients.

Supercarriers: Just 2% of SARS-CoV-2 positive people carry 90% of the virus

A new study published in the Proceedings of the National Academy of Sciences shows that the vast majority of the viral load in a community at any given point is present in a very small minority of the infected population, underlining the vast differences in viral loads between individuals.

A magnetofluidic platform for SARS-CoV-2 variant and respiratory pathogen detection

Recent research published on the medRxiv* server has developed a portable, magnetofluidic cartridge platform, for automated PCR testing in <30 min, for rapid multiplexed screening of pathogens. A multidisciplinary team of researchers at Johns Hopkins University and the Johns Hopkins University School of Medicine developed these cartridges for multiplexed detection of SARS-CoV-2 with distinctive variant mutations or with Influenza A and B.

Antibodies generated by malaria cross-react with SARS-CoV-2

An international team of researchers has warned that individuals with acute malaria infection generate high levels of antibodies that cross-react with the viral spike protein of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Single dose of Oxford-AstraZeneca vaccine protective in previously infected recipients, suggests study

A recent report on the medRxiv* preprint server suggests that a single dose of the Oxford-AstraZeneca (ChAdOx1 nCoV-19) vaccine could elicit higher titers of neutralizing antibodies, effectively acting as a booster dose, in people who have already been infected by the SARS-CoV-2.

Designer SARS-CoV-2 RBD vaccine produces dramatically improved antibody response in preclinical trials

The importance of computational modeling in the prediction of the course of the ongoing COVID-19 pandemic, as well as evaluating multiple potential drug leads, has never been more clear. Now, a new study describes a set of designer vaccine antigens that may improve vaccine stability as well as enhance the neutralizing antibody response.
