LIVE-AIR trial demonstrates efficacy of Lenzilumab for treatment of COVID patients with decreased oxygen saturation

The LIVE-AIR phase 3 clinical trial is associated with early treatment of hyperinflammatory response with the humanized monoclonal antibody lenzilumab in COVID-19 patients with decreased oxygen saturation. The study results are posted to the medRxiv* preprint server.

Inhaled CBD shrinks glioblastoma’s size in an animal model

Inhaled CBD shrinks the size of the highly aggressive, lethal brain tumor glioblastoma in an animal model by reducing the essential support of its microenvironment, researchers report.

Study reveals the role of intracellular receptor PQBP1 in response to Tau protein

Just as a home security system can alert a homeowner to the presence of an intruder, a protein called polyglutamine binding protein-1 (PQBP1) found in brain cells can alert the body to the presence of "intruding" viruses like human immunodeficiency virus (HIV).

Maternal-fetal interface yields intriguing clues to how it battles SARS-CoV-2

Scientists have hypothesized that the number of immune cells and the amount of cytokines produced in response to SARS-CoV-2 infection in pregnant women change in accordance with the timing of maternal infection in pregnancy. This study is available on the bioRxiv* preprint server.

Study may pave the way for a more personalized approach to COVID-19 diagnosis and treatment

Using some of the most advanced molecular sequencing tools available to evaluate COVID-19 rapid autopsy tissues, researchers have identified four major regulatory pathways, specific molecular effectors behind COVID-19 symptoms, and differences that drive diverging clinical courses among individual patients.

Alteration in gut microbiome may lead to hyperinflammation in severe COVID-19

A team of international scientists has recently identified a distinct set of proinflammatory mediators and metabolites associated with the fatal consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Moreover, they have established a link between gut microbiome alteration and hyper-inflammatory response in patients with severe COVID-19. The study is currently available on the bioRxiv* preprint server.
