Researchers stabilize the closed SARS-CoV-2 spike trimer

Now, a new study by researchers at Janssen Vaccines & Prevention BV and Leiden University and published on the preprint server bioRxiv uses cryoEM to reveal the structure of this trimer, in order to support both vaccine development and diagnostic testing based on antibody production.

Novavax SARS-CoV-2 vaccine candidate shows promise in animal models

A new study published on the preprint server bioRxiv in June 2020 shows that a candidate spike protein vaccine can induce neutralizing antibodies, antiviral T cell responses, and protection against infection.

Striking CryoEM image of SARS-CoV-2

A new study by researchers from the UK and Germany and published on the preprint server bioRxiv in June 2020 reports the results of a detailed study of the S protein on the intact virus, using cryoelectron microscopy (cryoEM) and tomography. This could help understand the conformation of the S protein on the virion and how it interacts with neutralizing antibodies.

Brain-transportable soy derivate reduces memory degradation in mice

In a study that could help one day give a literal meaning to food for thought, researchers from Kyushu University in Japan have reported that a protein fragment that makes its way into the brain after being ingested can reduce memory degradation in mice treated to simulate Alzheimer's disease.

How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.

Study reveals how essential SARS-CoV-2 protein can be stabilized and scaled for production

A research group from the University of Texas in Austin described a high-yield production of a stabilized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S-protein) that may accelerate the development of vaccines and diagnostic tests. This methodological 'tour de force' paper is currently available on the bioRxiv* preprint server.

Gut bacteria may predict risk of pulmonary hypertension

A team of researchers has found that the microflora of bacteria within the gut of humans could be a contributor to the development of pulmonary arterial hypertension (PAH). The study titled, "Altered Gut Microbiome Profile in Patients With Pulmonary Arterial Hypertension," in the latest issue of the American Heart Association's journal Hypertension.

Researchers propose new treatment strategy for colon cancer patients

Colorectal cancer is the fourth leading cause of cancer-related deaths worldwide. In a new study, researchers demonstrate for the first time that a previously uncharacterized protein is increased in colon cancer. The protein is immunoglobulin containing proline rich receptor-1 (IGPR-1) which was recently identified in the same laboratory as a cell adhesion molecule.

Study reveals how proline metabolism supports breast cancer metastasis

A multinational group of scientists, led by professor Sarah-Maria Fendt, have discovered that breast cancer cells that have invaded other organs rely on a different nutrient metabolism to produce energy than normal cells and non-metastasizing cancer cells.
