SARS-CoV-2 spike mutation can independently predict viral evolution

A team of scientists from Portugal has recently estimated the rate of mutation in two circulating variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using experimental evolution methods. Their findings reveal that in a condition with no immune surveillance, SARS-CoV-2 can potentially undergo evolution during the first stages of infection. The study is currently available on the bioRxiv* preprint server.

North America has 87% of all unique SARS-CoV-2 S protein variants in the NCBI database among six continents

Recently, a team of researchers from various countries analyzed the unique variants of S proteins across six continents, including Africa, Asia, Oceania, Europe, South America, and North America. They wanted to characterize the unique S protein variants embedded in SARS-CoV-2 genomes infecting millions of people globally.

Protein intake is more important than protein source to gain muscle strength and mass

Protein intake is more important than protein source if the goal is to gain muscle strength and mass.

SARS-CoV-2 mRNA vaccine PTX-COVID19-B safe and highly immunogenic in preclinical study

COVID-19, the coronavirus disease of 2019, is one of the worst pandemics in human history. It emerged in December 2019 and is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nearly 164 million SARS-CoV-2 infections and 3.4 million deaths have been reported globally since the beginning of the pandemic, which is still raging in many countries.

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.

Immunity developed by SARS-CoV-2 infection can protect against E484K variants, suggests study

A team of scientists from Japan has recently investigated the neutralizing potency of convalescent sera against currently circulating SARS-CoV-2 variants with multiple spike mutations.

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.

CNIO researchers unravel why motor neurons die in ALS patients

In Amyotrophic Lateral Sclerosis (ALS), the progressive death of neurons that control body movement leads to paralysis of muscles in the limbs and gradually of the whole body, which ultimately makes it impossible to breathe. ALS is currently untreatable, and its cause is unknown.

Researchers develop novel targeted therapy for triple-negative breast cancer

Researchers from Hong Kong Baptist University (HKBU), in collaboration with Cornell University, have developed a novel targeted therapy for triple-negative breast cancer (TNBC) that uses a specially-designed nano-carrier to deliver the Chinese medicine compound gambogic acid (GA).

Spread of minority SARS-CoV-2 variants in New York City

Viruses mutate to survive. But not all mutations are beneficial to the virus. On the other hand, some mutations such as N501Y and E484K on the spike protein propelled specific severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants to ‘variant of concern’ status, due to their ability to increase transmission and weaken the response of neutralizing antibodies.

Lab reports 1st instance of SARS-CoV-2 variants affecting antigen test performance

Researchers from the US recently determined the sensitivity of the Quidel Sofia SARS Antigen FIA test (Sofia 2). They found a high viral load specimen that tested negative repeatedly while using this antigen test. The study is published on the preprint server, medRxiv.

Researchers improve method to inhibit viruses that cause childhood respiratory infections

By engineering a short chunk of protein, or peptide, that can prevent the attachment of human parainfluenza viruses to cells, researchers have improved a method in rodent models intended to help keep children healthy.

Immunosuppression in COVID-19 promotes emergence of multiple immune escape mutants

An interesting new study describes the emergence of several such variants from a chronically immunosuppressed COVID-19 patient, who remained infected for over 170 days before clearing the virus.

The ancestor of SARS-CoV-2’s Wuhan strain was circulating in late October 2019

The SARS-CoV-2 was first reported in a case from Wuhan, China, in December 2021, and subsequently became the cause of the COVID-19 pandemic that is ravaging the world today. A new study in the journal Molecular Biology and Evolution tracks its variants all over the world since the onset of the pandemic.

Indian SARS-CoV-2 variant shows enhanced host cell entry and immune evasion

A study conducted by researchers in Germany has found that the B.1.617 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in India entered certain types of lung and intestine cells with slightly increased efficiency compared with the original wild-type strain.
