Researchers identify genetic mechanisms that produce radioresistance in cancer cells

Cancer stem cells are a cell type that was previously little known. They are resistant to irradiation and prevent the effective treatment of many types of cancer. A research group from Innsbruck has now identified two genetic mechanisms that produce this radioresistance.

Inherited genetic variations can alter progression of melanoma, indicates study

Sometimes cancer stays put, but often it metastasizes, spreading to new locations in the body. It has long been suspected that genetic mutations arising inside tumor cells drive this potentially devastating turn of events.

Even natural products may pose potential risk to unborn child

Plant products ingested by pregnant women through their diet are broken down by the intestinal microbiota into chemical substances, some of which can cross the placental barrier and reach the fetus.

New biomarkers to consider for SARS-CoV-2 vaccine

Researchers at the University of Melbourne have made new discoveries about how the immune system responds to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could be important to consider in vaccine research.

First COVID-19 vaccine found to be safe, able to generate rapid immune response in phase 1 clinical trial

The first COVID-19 vaccine to reach phase 1 clinical trial has been found to be safe, well-tolerated, and able to generate an immune response against SARS-CoV-2 in humans, according to new research published in The Lancet.

Different immune responses can occur in Covid-19, shows study

The human immune system is reactive to more than just the viral protein on which researchers have focused to date. This is relevant for tests and potential vaccines.

Blood test could reveal how the immune system responds to coronavirus

A highly detailed analysis of the composition of immune cells in the blood of patients with COVID-19, reveals new aspects of how the SARS-Cov-2 coronavirus causes disease.

New clinical trial to test treatment that targets overactive immune response to COVID-19

For some COVID-19 patients, the body's immune response may be as destructive as the virus that causes the disease.

Scientists identify compounds in noxious weed that reduce virulence of Staphylococcus bacteria

Scientists have identified specific compounds from the Brazilian Peppertree -- a weedy, invasive shrub in Florida -- that reduce the virulence of antibiotic-resistant staph bacteria.

Study to examine how stem cell transplant patients react to COVID-19 infection

A new study will look at how patients, who receive stem cell transplants for blood cancers and blood disorders, react to COVID-19 infection during their recovery.

IL-6 blocker use in severe COVID-19 increases risk of secondary infections

With many hundreds of thousands of deaths due to the current COVID-19 pandemic, there is a rush to find an effective vaccine or drug against the virus. A new study on the preprint server medRxiv* in May 2020 shows that the use of some biologically plausible drugs may be counterproductive, and care should be taken when trying out unproven therapies.

Simple molecular 'switch' transforms autoimmunity drugs into powerful anti-cancer treatments

Scientists from the Antibody and Vaccine group at the University of Southampton have discovered a way to transform antibody drugs previously developed to treat autoimmunity into antibodies with powerful anti-cancer activity through a simple molecular "switch".

ELISA and CLIA antibody tests for SARS-CoV-2 perform best in terms of sensitivity

Testing for those who have developed antibodies against the coronavirus can help tackle the ongoing COVID-19 pandemic. Now, a new study has identified all the antibody tests available for the coronavirus disease (COVID-19) to determine which performs better and is more accurate.

New guidance to mitigate the psychological effects of social distancing

New guidance published in The BMJ today during Mental Health Awareness Week has outlined guidance for primary care workers on the best-evidenced methods to mitigate the psychological effects of social distancing.

Study shows selenium-containing compounds inhibit SARS-CoV-2 replication and assembly

A recent paper by researchers from the Netherlands and Poland provides evidence that modified ebselen derivatives may serve as highly promising prospective drugs against coronavirus disease 2019 (COVID-19). The manuscript is freely available on the bioRxiv* preprint server.

Producing virus-specific antibodies after COVID-19

In order to design effective vaccines for COVID-19, we need to understand our immune responses. News-Medical speaks to Professor Chen Dong to find out more.

Lattice light-sheet microscopy could help in drug and vaccine development

From testing drugs to developing vaccines, the close study of the immune system is key to improving real-world health outcomes. T-cells are integral to this research, as these white blood cells help tailor the body's immune response to specific pathogens.
