Circadian rhythms help in brain's unique process of waste removal

New research details how the complex set of molecular and fluid dynamics that comprise the glymphatic system - the brain's unique process of waste removal - are synchronized with the master internal clock that regulates the sleep-wake cycle.

New theory changes the understanding of complex social interactions

Tracking the extent to which other people think differently from yourself appears to be more relevant than understanding someone else's thoughts per se. Neuroscientists at Ghent University and the University of New South Wales (Sydney) came to this conclusion.

Novel technique to detect the fungus responsible for causing severe pneumonia

Research staff of the University of Valencia and the Foundation for the Promotion of Health and Biomedical Research of the Valencian Community, among other institutions, have developed a very sensitive and fast in-vitro method for the diagnosis of infection by Pneumocystis jirovecii, a fungus that causes severe pneumonia.

Durable IgG antibodies to SARS-CoV-2 from the Iceland experience

Now, a team of scientists at the Reykjavik-based deCODe Genetics, a subsidiary of the U.S. biotech company Amgen, and several universities and hospitals in Iceland, says that the antibodies developed to fight SARS-CoV-2 last for at least four months and do not fade quickly as previously thought.

Exponential rise in COVID-19 hospitalization risk with age due to waning T cell immunity

The age-related increase in the risk of severe disease and death from COVID-19 mirrors earlier patterns seen with infections. Such trends may help understand the mechanisms underlying the clinical feature. A recent study published in the preprint server medRxiv* in August 2020 shows the effect of age and sex on COVID-19 hospitalization rates in the USA and helps understand how immune function is involved in this pandemic.

A global vaccine is sufficient to combat COVID-19 infection, indicates study

Genetic analysis of sequences from more than 27,000 individuals infected with the coronavirus that causes COVID-19 reveals that the virus has mutated minimally since December 2019, suggesting one vaccine would be sufficient to combat global infections.

Study: BIRC2 overexpression could be a key marker for immunotherapy resistance

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cell's natural "suicide" signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer.

ACE2/TMPRSS2 not expressed in pancreatic islet endocrine cells

A new study by researchers at the Vanderbilt University Medical Center and the University of Pennsylvania Perelman School of Medicine and published on the preprint server bioRxiv* in August 2020 reports that both key enzymes that are required for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into the human host cell are lacking in the beta cells of the pancreatic islet. This rules out the direct injury hypothesis for impaired glucose control in patients with COVID-19 disease.
