SARS-CoV-2 immunity may last over six months through antibody evolution and B cell memory

With the coronavirus disease 2019 (COVID-19) pandemic infecting over 52.7 million people around the world, and killing over 1.2 million, a large amount of research has tried to better understand immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes COVID-19.

Harnessing proteomics could improve therapeutic approaches to COVID-19

A research group in India has recently described how the field of proteomics could be pivotal in helping to tackle the current coronavirus disease 2019 (COVID-19) pandemic.

Antimalarials could disrupt SARS-CoV-2’s Nsp1 translation termination

A research team from the Engelhardt Institute of Molecular Biology in Russia have shown that Nsp1 – a non-structured protein present in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen – stimulates translation termination in the stop codon recognition stage. Studying and developing drugs that compete with Nsp1 for binding with the termination complex could therefore be a potential strategy for fighting against coronavirus disease 2019 (COVID-19).

MIT researchers unravel the molecular structure of key coronavirus protein

MIT chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein, called the envelope protein E, forms a cation-selective channel and plays a key role in the virus's ability to replicate itself and stimulate the host cell's inflammation response.

Study reveals a previously undetected repertoire of cancer driver genes

A new study, led by researchers from the University of California, Irvine, has deepened the understanding of epigenetic mechanisms in tumorigenesis and revealed a previously undetected repertoire of cancer driver genes.

Some people had non-neutralizing antibodies against SARS-CoV-2 prior to COVID-19

A recent study examined several medical records and found that while past human coronavirus exposures are not linked to decreased SARS-CoV-2 infections, they are associated with reduced COVID-19 severity.

Bispecific sybodies show potential against SARS-CoV-2

As the search for effective antivirals against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues, a new study published on the preprint bioRxiv in November 2020 discusses the role of synthetic nanobodies or sybodies in neutralizing the virus by binding to its receptor-binding domain (RBD) on the spike protein.

Promising SARS-CoV-2 N epitope for more accurate diagnostic and surveillance antibody testing

A new study published on the preprint server bioRxiv in November 2020 describes the virus's N protein as a promising epitope for serology.

SARS-CoV-2-induces temporary loss of smell in mice

Now, a new study published on the preprint server bioRxiv in November 2020 presents the onset of olfactory dysfunction (loss of smell) in mice infected with the virus, examining this process at the cellular level. In doing so, this study throws more light on this curious symptom and COVID-19’s manifestations outside the lungs.

Rhesus monkeys and cats potential spillover reservoirs for COVID-19 virus

A team of researchers from Switzerland, Costa Rica and Germany has conducted a study showing which animal species could potentially serve as spillback reservoirs of severe acute repertory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Antidepressant drug fluvoxamine may prevent some serious complications of COVID-19

In a preliminary study of COVID-19 patients with mild-to-moderate disease who were attempting to recover in their homes, researchers at Washington University School of Medicine in St. Louis have found that the drug fluvoxamine seems to prevent some of the most serious complications of the illness and make hospitalization and the need for supplemental oxygen less likely.

Common spike mutation may make SARS-CoV-2 more susceptible to a vaccine

A new study published in Science confirms that SARS-CoV-2 has mutated in a way that's enabled it to spread quickly around the world, but the spike mutation may also make the virus more susceptible to a vaccine.

Researchers discover a mechanism that cells use to degrade microRNAs

UT Southwestern researchers have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amounts of proteins in cells.

TMDU and Fujitsu complete cancer gene network analysis in less than a day

Tokyo Medical and Dental University and Fujitsu Laboratories Limited have recently completed, in less than a day, estimation of the network that represents the influence relationship between genes and prediction of their relationship with infiltration and metastasis based on genes highly likely to be involved in cancer development.

Study explores connection between internal biological clocks and beta cell regeneration

Certain parts of our body, such as the skin or liver, can repair themselves after a damage. Known as cell regeneration, this phenomenon describes how cells that are still functional start to proliferate to compensate for the loss.

Researchers identify acrylamides that inhibit SARS-CoV-2 main protease

A new study in the preprint server bioRxiv published in November 2020 describes the discovery of acrylamide fragments that can effectively disable key enzymes in both the hand, foot and mouth virus and SARS-CoV-2 virus.

Human coronaviruses cause processing body loss

Researchers continue to expand their knowledge of coronaviruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen. Now, a new study published on the preprint server bioRxiv in November 2020 describes a vital mechanism whereby the novel SARS-CoV-2 pathogen can restrict the human host response. In doing so, the study explores how this novel feature of SARS-CoV-2 works and how it results in a reshaping of the human host's immune response.
