Prior T cell immunity to SARS-CoV-2 unlikely to be the result of seasonal coronavirus infection

Scientists have suggested that a proportion of the population have pre-existing immunity to COVID-19 because of T cells primed against SARS-CoV-2 antigens.

Repair protein may prevent damage to healthy cells during cancer therapy

A key way radiation therapy and chemotherapy work is by making highly lethal double-strand breaks in the DNA of cancer cells.

Predicting SARS-CoV-2 protein sequences

SARS-CoV-2, the causative agent of COVID-19, consists of an assembly of proteins that determine its infectious and immunological behavior.

Researchers assess the binding behavior of SARS-CoV-2 virus

The binding of a SARS-CoV-2 virus surface protein spike -- a projection from the spherical virus particle -- to the human cell surface protein ACE2 is the first step to infection that may lead to COVID-19 disease.

Amilorides reduce SARS-CoV-2 viral replication in vitro

A new U.S. study published on the bioRxiv preprint server reports the use of an amiloride-based scaffold that targets a viral RNA structure known to be essential in viral replication in the 5’-untranslated region (UTR) of the virus. The researchers say this heralds the application of these molecules as chemical probes to explore viral biology and produce specific antivirals targeting RNA regions of the coronavirus genome.

Researchers develop a promising fix to CRISPR-Cas9's unwanted changes problem

A group of researchers developed a promising fix to CRISPR-Cas9's problem with unwanted genetic changes using a method that allows them to turn off gene-editing until it reaches key cell cycle phases where more accurate repairs are likely to happen.

N-Glycosylation sites may contribute to spike-mediated invasion by SARS-CoV-2

The sugar residues decorating the spike (S) protein of SARS-CoV-2 are essential to the viral-receptor binding.

Study: Tumors with high TMB tend to respond better to immune checkpoint inhibitors

Treatments that harness the immune system to fight cancer have greatly improved outcomes for some people with cancer. Scientists are learning more about why some people respond much better than others to these drugs.

Research shows a unique T cell receptor repertoire in MIS-C patients

Children with coronavirus disease 2019 (COVID-19) sometimes develop the Multisystem Inflammatory Syndrome in Children (MIS-C), which is associated with high morbidity. The underlying T-cell associated mechanism is described by researchers in a new study published on the preprint server bioRxiv in November 2020, as a response to superantigen activation.

Discovery of novel hidden gene in SARS-CoV-2

A team of researchers from Germany, Taiwan, and the United States has identified and characterized a new hidden gene in SARS-CoV-2 that is also present in Guangxi pangolin coronaviruses – though, curiously, absent in closely related pangolin and bat coronaviruses.

USask researchers to study how cannabis use during pregnancy affects fetus' brain development

University of Saskatchewan pharmacologist Robert Laprairie will use a Brain Canada research grant to determine how a mother's use of cannabis during pregnancy affects the brain of the developing fetus she's carrying.

Biomarkers that are predictive of clinical benefit in Trop-2-expressing triple-negative breast cancer

Oncotarget recently published "Predictive biomarkers for sacituzumab govitecan efficacy in Trop-2-expressing triple-negative breast cancer" which reported that the authors investigated whether Trop-2-expression and homologous recombination repair of SN-38-mediated double-strand DNA breaks play a role in the sensitivity of triple-negative breast cancer to SG.

Scientists compare ACE2 interaction with SARS-CoV-2 across species

Like other pathogenic coronaviruses, SARS-CoV-2 crossed the species barrier to cause human disease. This fact motivated the current study, published on the preprint server bioRxiv* in October 2020, which explores the way coronaviruses engage their host cell receptors in a range of animals.

Antigenic imprinting of sarbecovirus

A recent study published on the preprint server bioRxiv* in October 2020 shows that the design of a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) must consider the prior history of exposure to coronaviruses since these affect the antibody response to the virus.

19 Oct 2020

Newly identified coronavirus epitopes induce robust antibody responses

Researchers at the University of Wisconsin-Madison have conducted a study showing that infection with severe acute respiratory syndrome coronavirus 2 (SARS-C0V-2) triggers robust immune responses to epitopes across the full viral proteome.

Cats and dogs are low risk for SARS-CoV-2 transmission to humans

Researchers from the College of Veterinary Medicine and Biomedical Sciences, Colorado State University studied the possible transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among domestic cats and dogs.

PROfound phase III results offer new targeted treatment for metastatic prostate cancer

Results from the PROfound phase III study, funded by AstraZeneca and Merck Sharp & Dohme, open up a much-needed new treatment avenue for the more precise and effective treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) whose disease has progressed with hormonal therapy.

Spike-based priming leads to high neutralizing activity in animal models

A new report by researchers at the University of Melbourne and published on the preprint server bioRxiv in September 2020 reports on the use of a two-protein two-dose vaccine regimen and its immunogenicity in two animal models.

4 Sep 2020

Understanding SARS-CoV-2 evolution requires more focus on structural variants

Researchers in the United States and Canada warn that more attention needs to be paid to the role that structural variants and recombination in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have played in the evolutionary history of the virus.

New bioluminescent reporter developed to track DNA double stranded break repair

A new bioluminescent reporter that tracks DNA double stranded break repair in cells has been developed by researchers from Massachusetts General Hospital and the Academia Sinica in Taiwan.
