Human organoids useful for modeling COVID-19 variants of concern, finds study

A new study published on the bioRxiv* preprint server found that using human organoids could help with better characterizing the phenotype of several viral variants, including B.1.1.7. Their findings show the ribonucleic acid (RNA) shedding of the SARS-CoV-2 variant correlated with viral fitness and infectiousness.

Increased symptomatic levels of COVID-19 may be associated with psychiatric symptoms

A significant level of symptoms of depression, anxiety and post-traumatic stress may follow COVID-19 independent of any previous psychiatric diagnoses, according to new research by Columbia University Mailman School of Public Health with colleagues at Universidade Municipal de São Caetano do Sul in Brazil.

Highly efficient immune response in asymptomatic SARS-CoV-2 patients

Researchers in Singapore have investigated the role of SARS-CoV-2-specific antibodies and T-cells in asymptomatic individuals suffering from COVID-19. They found that, contrary to some initial hypotheses, asymptomatic individuals mount an adaptive immune response on par with symptomatic individuals, demonstrating that T cell response does not appear to be correlated with symptom severity.

Researchers discover new binding sites for active agents on cell cytoskeleton

Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before. The study appears today in the journal Angewandte Chemie International Edition.

Molecular clues explain why some neurons are more susceptible than others in Alzheimer’s disease

In the brain of a person with Alzheimer's disease, neurons degenerate and die, slowly eliminating memories and cognitive skills. However, not all neurons are impacted equally.

SARS-CoV-2 infection prolongs viral shedding and lymphocyte loss in patients with cancer

Patients with cancer have a more challenging time with infections while undergoing treatment — placing them as high-risk for severe COVID-19 illness and death. However, how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with cancer therapies remains poorly understood.

Bubonic plague had long-term impact on human immune genes, indicates study

Scientists examining the remains of 36 bubonic plague victims from a 16th century mass grave in Germany have found the first evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.

Study reports vitamin C inhibits SARS-CoV-2 virus main protease

Based on structural analysis, researchers found that vitamin C binds to 3CLpro, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease essential in viral replication. In vitro cell inhibition studies also showed vitamin C could inhibit 3CLpro, indicating a possible new antiviral treatment method.
