Scientists identify sensor in human lungs that detects SARS-CoV-2

Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it's time to mount an antiviral response.

Antibody-Fc-mediated innate immunity shapes COVID-19 severity

A short paper that appeared recently on the preprint bioRxiv server pointed to a link between specific characteristics of anti-SARS-CoV-2 antibodies associated with the severity of COVID-19.

Intranasal vaccination effectively reduces viral shedding of SARS-CoV-2 in monkeys

A new preprint that appeared on the bioRxiv server reports that intranasal vaccination with the D614G variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in rhesus monkeys reduces viral shedding. This is an experiment in non-human primates (NHP), and its extrapolation to humans is unclear as yet.

Structure of SARS-CoV-2 cytoplasmic tail uncovered

The virus's cytosolic tail also interacts with the host cell to promote its entry into the endoplasmic reticulum (ER). A new study appearing on the bioRxiv preprint server elucidates the conformation of this region of the virus, which will help understand how its form is related to its function in viral entry.

Effect of mutations in the South African SARS-CoV-2 variant on transmission and neutralization

One such strain is the South African 501.V2 and UK B1.1.7 strains, which have been isolated from many countries and seem to spread faster than the ancestral strain. A preprint that recently appeared on the bioRxiv server reports the computational structure of this strain and the possible effect of the mutations on infectivity and neutralization.

Daily circadian cycles may impact our ability to fight disease

An analysis of an exhaustive dataset on cells essential to the mammalian immune system shows that our ability to fight disease may rely more heavily on daily circadian cycles than previously assumed.

Researchers discover a new approach to inhibit intrahepatic cholangiocarcinoma

Reprogramming the rich connective tissue microenvironment of a liver cancer known as intrahepatic cholangiocarcinoma (ICC) inhibits its progression and resistance to standard chemotherapy in animal models, researchers from Massachusetts General Hospital have found.

Antigenic "supersite" could improve design of COVID-19 vaccines

Researchers in the United States have defined an antigenic “supersite” within the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could have important implications for the design of vaccines to protect against coronavirus disease 2019 (COVID-19).

Scientists determine ideal dose of stem cells to control HIV

Scientists have determined the optimal conditions following a stem cell transplant that could control HIV without the need of an everyday pill, according to a study published today in eLife.

Study investigates the metabolites involved in growth and spread of melanoma

The first step in treating cancer is understanding how it starts, grows and spreads throughout the body. A relatively new cancer research approach is the study of metabolites, the products of different steps in cancer cell metabolism, and how those substances interact.

Hypoxia signaling pathway could lead to COVID-19 treatments

Researchers in Spain have demonstrated that studying the hypoxia signaling pathway could provide opportunities for treating coronavirus disease 2019 (COVID-19).

Study shows how brain molecules work in conjunction to create architectural marvels

In a study published in Cell Reports, researchers at Kanazawa University identify pathways in the brain which enable neurons to assemble into functional units resembling tall columns.

Nanobodies have potential to be developed into a treatment for COVID-19

Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells.

Rotten egg gas may help protect aging brain cells from Alzheimer’s disease

Typically characterized as poisonous, corrosive and smelling of rotten eggs, hydrogen sulfide's reputation may soon get a face-lift thanks to Johns Hopkins Medicine researchers.

UTSW study uncovers a gene linked to growth of breast cancer

A team of UT Southwestern researchers has identified a gene involved in the growth of breast cancer, a finding that could lead to potential new targets for treatment.

Boosting a natural cellular process could lower ventilator-related lung damage

An unfortunate truth about the use of mechanical ventilation to save the lives of patients in respiratory distress is that the pressure used to inflate the lungs is likely to cause further lung damage.

Advanced humanized mouse model helps better understand immunotherapy resistance in melanoma

Scientists at The Wistar Institute have created an advanced humanized immune system mouse model that allows them to examine resistance to immune checkpoint blockade therapies in melanoma. It has revealed a central role for mast cells. These findings were published today in the journal Nature Communications.
