Defective epithelial barrier responsible for up to two billion chronic diseases

Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.

Unemployed Australian citizens experience mental health deterioration during COVID-19 pandemic, finds study

A team of scientists in Australia has recently investigated the health condition of Australian citizens who lost jobs during the coronavirus disease 2019 (COVID-19) pandemic. The study findings reveal that job loss is associated with a deterioration in mental health but an improvement in physical health. Importantly, retaining employment has shown a positive impact on the overall mental health condition.

SARS-CoV-2 is activated for fusion by a broad range of proteases, finds study

A team of researchers from the University of Virginia, USA, used single-virus fusion experiments with exogenously controlled proteases to investigate the mechanism of activation directly. They found that the subcellular location of entry depends on the protease activity of the various components, and parallel pathways are possible.

New method shows that tau forms small aggregates as part of the body's normal physiology

It turns out that not all build-ups of tau protein are bad, and a team of researchers from the Perelman School of Medicine at the University of Pennsylvania developed a method to show that.

Transplant recipients with COVID-19 may show lower cellular and antibody immune responses

Transplant patients are typically on chronic immunosuppression, making them automatically more vulnerable to infection with SARS-CoV-2, the agent responsible for the loss of over three million lives in the current COVID-19 pandemic. A new study discusses evidence for subnormal immune responses following COVID-19 in this population.

Aberrant immune features in healthy elderly and male subjects with severe COVID-19 may predate infection

A new study shows that the immunological features of severe COVID-19 are already present in healthy older adults and in men, before they are infected, indicating a possible explanation for this differential susceptibility towards the virus.

Could stem cells improve the outcome of ARDS in severe COVID-19?

A recent study, published in Stem Cells Translational Medicine, explores the safety and efficacy of stem cells, which have been touted as the panacea for a wide range of illnesses, ranging from chronic degenerative conditions to cancer.

About 84% of antibodies in plasma target non-RBD epitopes on SARS-CoV-2 spike protein, finds study

In a new study recently published in the journal Science, a team of researchers in the U.S. found that most of the antibodies circulating in the blood target areas of the viral spike protein outside the receptor-binding domain (RBD), the part of the spike that binds directly to human cell receptors.

Moderate alcohol intake may be heart protective by reducing stress-related brain signals

Moderate alcohol intake--defined as no more than one alcoholic drink for women and two for men per day--has been associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study being presented at the American College of Cardiology's 70th Annual Scientific Session.

Researchers develop a multivalent vaccine for COVID-19 and influenza

Researchers at Duke University, USA, are looking into the possibility of a combined influenza and COVID-19 vaccine that could be used to simultaneously protect against annual flu strains and the SARS-CoV-2. Preclinical results showed the vaccine protected mice from both SARS-CoV-2 and the flu.

Visual brain areas also encode the proper way to hold tools

Visual brain areas involved in processing hands also encode information about the correct way to hold tools, according to new research published in JNeurosci.

New imaging technique captures real-time brain motion in stunning detail

Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.

Mammalian olfactory system is also crucial in processing space and surroundings, indicates study

Researchers at the Francis Crick Institute and UCL (University College London) have found that mice can sense extremely fast and subtle changes in the structure of odors and use this to guide their behavior.

Study reveals a new form of muscular dystrophy associated with pathogenic changes in JAG2 gene

In about a quarter of patients with hereditary diseases, the cause of the disease remains unclear even after extensive genetic testing. One reason is that we still do not know enough about the function of many genes. Of the 30,000 known genes, just a little more than 4,000 have been found to be associated with hereditary diseases.
