Intranasal COVID-19 vaccine developed from bacterial extracellular vesicle induces robust antibody response in preclinical trials

A team of US-based scientists recently developed a novel vaccine candidate against SARS-CoV-2, the causative pathogen of COVID-19. The vaccine is composed of extracellular vesicles of Salmonella typhimurium incorporated with the spike receptor-binding domain (RBD) of SARS-CoV-2. Upon intranasal administration in hamsters, the vaccine induces strong blood antibody titers and protects against severe COVID-19.

SARS-CoV-2 infection induces accumulation of lipids and N-proteins

Scientists from the Netherlands and the US recently studied the localization of the SARS-CoV-2 proteins in postmortem lung tissues of COVID-19 patients and in SARS-CoV-2 infected Vero cells that were processed identically. The research is posted to the bioRxiv* preprint server, prior to peer review.

New study reveals how heparan sulfate promotes amyloid deposition in various organs

Amyloid diseases, including Alzheimer's, Parkinson's, type-2 diabetes and other life-threatening diseases, involve pathologic deposits of normally soluble proteins or peptides as insoluble amyloid fibrils. When this happens in vital organs, such as the brain, kidney, liver and heart, it causes organ damage and, if left untreated, death. Unfortunately, the available treatment options are very limited.

Researchers determine molecular structure of bacterial protein complex critical for tuberculosis

Tuberculosis is one of the top ten causes of death worldwide, infecting about one-quarter of the world's population. Although it is treatable, the rise of multidrug-resistant tuberculosis poses a major threat to global health security, and has been declared by the World Health Organization as a global health emergency.

A closer look at how COVID-19 damages human lungs

A recent study conducted at the United States Department of Energy’s (DOE) Brookhaven National Laboratory provides the first atomic-level detailed model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope protein when bound to human proteins within the lungs. The study was recently published in Nature Communications.

Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.
