Autoimmune antibodies strongly linked to the severity of illness in COVID-19 patients

The presence of special immune system defense molecules, called autoimmune antibodies, has been strongly tied to how poorly people fare when hospitalized with COVID-19, a new study shows.

Could soluble CD24 offer some hope against severe COVID-19?

A recent randomized phase III trial conducted by researchers at the Ohio State University, Columbus, OH, US, evaluated the impact of CD24Fc in severe COVID-19 patients and showed promising clinical efficacy. This study is available as a preprint on the medRxiv* server.

New streamlined approach for high-coverage genome sequencing of single yeast cells

A single cell can reveal much about the biological world through genomic sequencing. Scientists can compare a single, isolated cell to other samples, analyzing the differences and similarities to better understand how the organisms originated and evolved -; or even to discover entirely new species.

Engineered T cells prevent translational shutdown in SARS-CoV-2 infected cells

In a paper recently uploaded to the preprint server bioRxiv* by Schamel et al. (June 25th, 2021) engineered T cells against SARS-CoV-2 are tested against a range of cells in vitro, finding that the treatment could be used to restore cellular immune function and suppress SARS-CoV-2.

Gasdermin D plays a key role in the maturation and release of IL-1α

Interluekin-1α (IL-1α) is an important part of the immune response, but until now it has been unclear how this molecule is processed from its precursor, pro-IL-1α, and exits the cell during inflammasome activation.

BCG vaccination appears to trigger cross-reactive SARS-CoV-2-specific T cell response

Recently, researchers from the Monash University and Monash Medical Centre, Clayton, Victoria, Australia, investigated whether peptide sensitization using BCG can produce cross-reactive T cells specific to SARS-CoV-2. Their study is published on the preprint server, medRxiv.

Using 'own' immune cells to fight infectious diseases including COVID-19

A provocative paper from Duke-NUS Medical School, published in the Journal of Experimental Medicine in March 2020, discusses the possibilities of creating new receptors on a sick person's own immune cells as a means of controlling the infection. This therapy is already being used to treat certain cancers with marked success.

Prenatal single cell blood test for gene defects

With the current state of knowledge regarding genetic testing, non-invasive prenatal testing (NIPT) is in favor for genetic testing in unborn babies, using fragments of DNA circulating in the mother’s blood.

Researchers reveal how antibodies assemble to form a circle for defensive attack

Antibodies are key players in our immune system. These antibodies recognize antigens displayed on foreign cell membranes and thereby recruit attacking forces, called complements.

Nanoscale syringe-like bacterial structures could be used to deliver novel drugs

By scraping tubeworms off the bottom of boats in the San Diego harbor to study them, San Diego State University researchers discovered that a beneficial bacterium that aids them in establishing colonies could also be a boon for human health, because the same process might already take place in the human gut.

Study shows how bacteria can destroy host cells from the inside

A bacterial pathogen that typically multiplies outside of host cells can enter and induce the destruction of cells called macrophages, according to a study published June 20 in the open-access journal PLOS Pathogens by Anne-Béatrice Blanc-Potard of the Université de Montpellier in France, and colleagues.

Bacteria use viruses for self-recognition, study reveals

Bacterial cells that normally colonize our guts can distinguish themselves from other bacterial species using what's traditionally considered their enemy--a virus.

Study reveals unknown mechanism that protects tumor cells from NK cell-mediated cytotoxicity

Cancer cells have evolved multiple escape strategies to circumvent the body's immune defenses such as the attack by Natural Killer (NK) cells which normally swiftly kill abnormal cells by releasing cytotoxic products.
