Researchers are working to advance device for detecting ultra-low levels of disease particles

In Judith Su's Little Sensor Lab, researchers are working to sense tiny amounts - down to a single molecule - of everything from doping agents to biomarkers for cancer, Alzheimer's disease, Lyme disease and, yes, even COVID-19.

FDA approves Regeneron antibody drug as first treatment for Ebola virus

Today, the U.S. Food and Drug Administration approved Inmazeb (atoltivimab, maftivimab, and odesivimab-ebgn), a mixture of three monoclonal antibodies, as the first FDA-approved treatment for Zaire ebolavirus (Ebola virus) infection in adult and pediatric patients.

Army researchers team up to test alternative ways to measure COVID-19 antibody levels

Researchers with the U.S. Army Futures Command are part of a team that tested alternative ways to measure COVID-19 antibody levels, resulting in a process that is faster, easier and less expensive to use on a large scale.

Exploring the effects of smoking tobacco on COVID-19 risk

A study conducted by researchers in China has shed light on how certain tobacco compounds might prevent cells from becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Researchers use single cell sequencing technology to characterize immune system of COVID-19 patients

In this study, which was published in the journal Frontiers in Immunology on September 30th, researchers used sequencing to characterize the immune system of patients who survive from COVID-19 infection from symptom onset through recovery.

G protein-coupled receptors help humans taste, smell, and regulate mood and immunity

Dr. Guangyu Wu is dissecting the molecular homing that enables a nascent protein to ultimately find its way to the surface of a cell as a mature receptor type that helps us taste, smell and even regulate our mood and immunity.

Study provides new insight into unknown effects of factors that regulate blood vessel formation

A new study by researchers at the University of Eastern Finland provides novel insight into the previously unknown effects of factors regulating blood vessel formation.

ACE2 binding causes dissociation of trimeric SARS-CoV-2 spike, may be used to inhibit further infection

A recent study published on the preprint server bioRxiv in October 2020 shows that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binding to the human host receptor could cause the typical trimeric spike protein to come apart, forming a stable monomer instead with the receptor.

Study shows SARS-CoV-2 antibodies offer lasting immunity

One of the most significant questions about the novel coronavirus is whether people who are infected are immune from reinfection and, if so, for how long.

Amino acid produced by the brain could prevent temporal lobe epileptic seizure

A team of researchers from the Florida State University College of Medicine has found that an amino acid produced by the brain could play a crucial role in preventing a type of epileptic seizure.

SARS-CoV-2 spike protein triggers cell signaling pathways in lung vascular cells

A new study published on the preprint server bioRxiv in October 2020 shows that vascular cells in the lung tissue begin to secrete signaling growth factors when exposed to just the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), without the rest of the viral components.

Study determines mechanisms underlying abnormal development of nervous system in Hirschsprung disease

Ankush Gosain, MD, PhD, of Le Bonheur Children's Hospital and the University of Tennessee Health Science Center has focused his research on determining the mechanisms underlying abnormal development of the enteric nervous system in Hirschsprung disease.

14 Oct 2020

New clinical trial to test safety and efficacy of antibody cocktail against COVID-19

In a new clinical trial, UC Davis Health will test the effectiveness and safety of REGN-COV2, the monoclonal antibody cocktail, in preventing COVID-19 in adults living with infected patients.

D614G mutation in SARS-CoV-2 increases viral fitness and infectivity

Researchers from the Duke Human Vaccine Institute and Duke University, Durham NC, USA, recently analyzed the D614G mutation in SARS-CoV-2 in the context of a soluble S ectodomain construct. Their study has been published in the preprint server bioRxiv.

Study finds sex differences among young individuals who suffer a heart attack

Women aged 50 or younger who suffer a heart attack are more likely than men to die over the following 11 years, according to a new study published today (Wednesday) in the European Heart Journal.

Cancer-killing T cells release chemicals to direct swarms towards tumors

When immune system T cells find and recognise a target, they release chemicals to attract more T cells which then swarm to help subdue the threat, shows a new study published today in eLife.

Mothers transmit passive protection against SARS-CoV-2 to their newborns

A recent study published on the preprint server medRxiv in October 2020 shows that newborns may be protected from acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection by antibodies in the mother’s blood that travels through the placenta.

Bacterial toxin stimulates tissue regeneration

Normally they are among the many harmless organisms found in and on the human body: one in four people have millions of Staphylococcus aureus bacteria on their skin and on the mucous membranes of the upper respiratory tract, without being aware of it.
