People may have a pre-existing immune response to COVID-19 thanks to common colds

Now, a new study shows that some people have immune responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, thanks to how the body reacted the last time it caught a cold. This means that even if a person has not been exposed to the novel coronavirus, the body has a memory of it and can trigger an immune response to fight the infection.

Iota-carrageenan from red seaweed inhibits SARS-CoV-2 in laboratory conditions

In a recent bioRxiv paper, a research group from the Marinomed Biotech biopharmaceutical company in Austria showed that a sulfated polysaccharide iota-carrageenan has the propensity to inhibit cell entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using an in vitro neutralization assay.

Face masks do not lead to false sense of security, shows study

Existing limited evidence suggests that wearing face coverings to protect against COVID-19 does not lead to a false sense of security and is unlikely to increase the risk of infection through wearers foregoing other behaviours such as good hand hygiene, say researchers from the University of Cambridge and King's College London.

Genes associated with SARS-CoV-2 human lung cell infection

Now, a new study published on the preprint server bioRxiv in June 2020 attempts to make sense of this data to identify viral genes that are explicitly expressed in the cells infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could help reveal new therapeutic targets.

Steroidal drugs subvert SARS-CoV-2 interaction with ACE2 receptors

A new study by Italian researchers and published online on the preprint server bioRxiv* in June 2020 reports the ability of several existing steroidal drugs to reduce the binding of the SARS-CoV-2 to the ACE2 receptor. This could help define newer strategies using viral entry blockers to reduce viral load.

COVID-19 mouse model could accelerate the search for treatments, vaccines

The global effort to quickly develop drugs and vaccines for COVID-19 has been hampered by limited numbers of laboratory mice that are susceptible to infection with SARS-CoV-2, the virus that causes COVID-19.

Universal preoperative screening of pediatric patients for COVID-19 improves safety

Universally screening pediatric patients for COVID-19 before they undergo surgical procedures has allowed hospitals to improve safety by identifying all patients who test positive for the virus, half of whom have no symptoms, according to new research led by Children's Hospital of Philadelphia

Study sheds new light on how respiratory virus breaks into cells to cause infection

New research from University of Alberta microbiologists has shed new light on how the respiratory syncytial virus (RSV)--one of the most common viral infections--breaks into our cells to cause infection.

High prenatal choline levels may mitigate negative effects of COVID-19 on newborns

Pregnant women who take extra choline supplements may mitigate the negative impact that viral respiratory infections, including COVID-19, can have on their babies, according to a new study from researchers in the Departments of Psychiatry and Obstetrics and Gynecology at the University of Colorado Anschutz Medical Campus.

Placentas of pregnant women with COVID-19 showed abnormalities

A study conducted by researchers at Northwestern University, Chicago, has found that the placentas of pregnant women who were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) showed abnormalities, compared with those of uninfected women.

Born into a pandemic: Virus complicates births for moms and babies

Mallory Pease's contractions grew stronger as her husband, Mitchell, drove her to Oaklawn Hospital in Marshall, Michigan, to give birth to their second child. It had been a routine pregnancy, but she told her doctor she'd recently developed a sore throat, aches, coughing and shortness of breath — symptoms her provider knew could indicate COVID-19.
