Obesity changes ACE2 and TMPRSS2 expression in mice: Implications for COVID-19

Researchers studying young obese mice found that expression of ACE2, a receptor in host cells that binds to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is higher in the lungs and trachea of obese mice. The finding could partly explain why obesity is a high-risk factor for COVID-19.

Researchers aim to identify disease tolerance mechanisms in sepsis patients

Sepsis is estimated to cause 11 million deaths every year in the world. Its treatment is based on the use of antibiotics and organ support measures, but many times it fails due to unsuccessful attempts at modulating the immune response.

High-titer convalescent plasma reduced COVID-19 symptom severity in green monkeys

As scientists scramble to find effective vaccines and antivirals for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a recent study published on the preprint server bioRxiv in October 2020 reports that the use of convalescent plasma to treat COVID-19 disease early in the course of the illness may be among the best available strategies at present.

New technique uses ultrasound to provide non-invasive assessments of lung health

Researchers from North Carolina State University and the University of North Carolina have developed a technique that uses ultrasound to provide non-invasive assessments of pulmonary fibrosis and pulmonary edema.

Obese persons have greater risk of developing severe COVID-19

The probability that an obese person will develop severe COVID-19 is high regardless of age, sex, ethnicity, and the presence of co-morbidities such as diabetes, high blood pressure, and heart or lung disease, according to a study by Brazilian researchers published in Obesity Research & Clinical Practice.

Researchers are working to advance device for detecting ultra-low levels of disease particles

In Judith Su's Little Sensor Lab, researchers are working to sense tiny amounts - down to a single molecule - of everything from doping agents to biomarkers for cancer, Alzheimer's disease, Lyme disease and, yes, even COVID-19.

Salivary samples highly effective in detecting SARS-CoV-2

A team of scientists from the United States has found that oral salivary samples are less sensitive than nasal-oropharyngeal swabs for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA

Drug derived from a natural human protein could stop lethal lung damage from the flu

The raging lung inflammation that can contribute to death from the flu can be stopped in its tracks by a drug derived from a naturally occurring human protein, a new animal study suggests.

COVID-19 causes potentially damaging neurological injuries, study shows

Without directly invading the brain or nerves, the virus responsible for COVID-19 causes potentially damaging neurological injuries in about one in seven infected, a new study shows.

COVID-19 vaccine candidate shows potent immune response

A COVID-19 vaccine candidate that underwent extensive preclinical testing at the University of Alabama at Birmingham this spring and summer shows potent preclinical immune responses -; including several that distinguish it from other COVID-19 vaccine approaches -; according to a preprint deposited in the BioRxiv repository this week.

Integrin b3 and ACE2 linked by short linear motifs enabling endocytosis and autophagy of SARS-CoV-2

A new study by Uppsala University researchers published on the preprint server bioRxiv in October 2020 shows possible links between the angiotensin-converting enzyme 2 (ACE2) host cell receptors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the entry of viral particles into the cell via endocytosis and autophagy.

Nasal spray COVID-19 vaccine shows promising results in mice

With promising vaccines comes a new candidate that has shown potent pre-clinical immune responses. The vaccine, developed by scientists at the University of Alabama at Birmingham (UAB), induced a potent T-cell response at the mucus layer of the lungs, including killer CD8+ T-cells, which can recognize and kill virally infected cells.

Intelligent robotic system to make colonoscopy easier for doctors

Scientists have made a breakthrough in their work to develop semi-autonomous colonoscopy, using a robot to guide a medical device into the body.

COVID stalks Montana town already saddled with asbestos disease

Like thousands of people from Libby and Lincoln County in the far northwestern corner of Montana, the 61-year-old Fahland has scarred lungs after years of breathing in asbestos fibers from dust and soil contaminated by the town's now-defunct plant that produced vermiculite, a mineral used in insulation and gardening.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

Antibody cocktail may offer clinical benefit in both prevention and treatment of COVID-19

In June, two studies in Science reported an antibody cocktail against SARS-CoV-2 developed from studies in humanized mice and recovering patients. The two antibody cocktail was designed to bind the virus to reduce the risk of a drug-resistant form emerging.
