Researchers discover mechanism behind loss of smell in people with COVID-19

Researchers have discovered a mechanism that may explain why people with COVID-19 lose their sense of smell.

The ability of individuals to cross-recognize the Omicron spike protein following vaccination or prior infection

Scientists studied the ability of T cells to react with the Omicron spike.

Assessing an intranasal lentiviral booster against COVID-19 variants

A new study explores the possibility of vaccination via nasal route utilizing a lentiviral vaccination vector (LV) to be administered as a booster dose against COVID-19.

Representative structures of SARS-CoV-2 and development of therapeutic agents for targeting these proteins

Researchers from China summarized the representative structures of SARS-CoV-2 proteins and discussed the development of novel therapeutic agents for targeting these proteins to treat and prevent COVID-19.

New approach to CAR T-cell therapy for B-cell cancers triples the targeted antigens on cancer cells

Researchers at University Hospitals Seidman Cancer Center and Case Western Reserve University have developed a novel approach to chimeric antigen receptor (CAR) T-cell therapy for B-cell cancers that triples the targeted antigens on cancer cells – a "back up" approach that promises to greatly reduce the potential for antigen escape currently found in CAR T therapies that solely target CD19.

New nanoparticle SARS-CoV-2 vaccine shows stronger, broader, and more durable protection

The first generation of COVID-19 vaccines have been highly effective, but also have limitations: their efficacy can wane without a booster shot, and they may be less effective against some variants.

Gut bacteria transfer genes through sex to take vitamin B12, study shows

Your gut bacteria need vitamin B12 just as much as you do. Though DNA is usually passed from parent to child, new research shows gut bacteria transfer genes through "sex" in order to take their vitamins.

Research supports the need for a 3rd mRNA COVID vaccine in patients taking immunosuppressants

New research posted to the medRxiv* preprint server finds patients with immune-mediated inflammatory diseases undergoing anti-TNF therapy had the greatest reduction of antibody levels three months after vaccination. In addition, they had weaker neutralization responses towards severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern.

Experimental immunotherapy could help treat some people with metastatic breast cancer

An experimental form of immunotherapy that uses an individual's own tumor-fighting immune cells could potentially be used to treat people with metastatic breast cancer, according to results from an ongoing clinical trial led by researchers at the National Cancer Institute's Center for Cancer Research, part of the National Institutes of Health.

COVID-19 vaccines induce robust cellular immune response against SARS-CoV-2 Omicron

A team of scientists from the United States has recently demonstrated that current coronavirus disease 2019 (COVID-19) vaccines induce robust spike-specific T cell responses against the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Liver hormone suppresses alcohol consumption in primates, study shows

A hormone produced by the liver called fibroblast growth factor 21 (FGF21) suppresses alcohol consumption in primates, finds a study published February 1 in the journal Cell Metabolism.

Study confirms SARS-CoV-2 Omicron variant has a decreased ability to enter lung cells

A large multinational group of researchers has shown how the Omicron variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has gained exceptional immune evasion properties but also a much lower propensity to enter cells such as those in lung alveoli, resulting in its reduced pathogenicity. Their paper is currently released as an unedited version of the manuscript prior to publication in the journal Nature.

Nanomedicine can be improved with proper and more predictive in vitro assays

Messenger RNA (mRNA) vaccines are a prime example of the promising field of nanomedicine. But progress in the design and application of nanoparticles as efficient delivery vehicles for biopharmaceutics containing nucleic acid or protein drug substances is, unfortunately, remarkably slow.

Developing post-vaccination SARS-CoV-2 standard reference sera

A new study reports the generation of reference sera reagents that were obtained from subjects vaccinated with one of four COVID-19 vaccines.

Individual dosing of preparatory drug makes stem cell transplants safer for children

Individual dosing of a drug used to prepare children for stem cell transplantation makes this treatment safer. That's according to new research by scientists from the Princess Máxima Center and the Wilhelmina Children's Hospital.

Researchers generate a complex kidney-like 3D tissue in the lab

A research team based in Kumamoto University (Japan) has created complex 3D kidney tissue in the lab solely from cultured mouse embryonic stem (ES) cells.

Researchers discover why patients suffering with hypertension also have diabetes

The long-standing enigma of why so many patients suffering with high blood pressure (known as hypertension) also have diabetes (high blood sugar) has finally been cracked by an international team led by the universities of Bristol, UK, and Auckland, New Zealand.

New RNA therapies for the treatment of heart failure and organ fibrosis

RNA has already been making an impact in the context of the vaccine program, but the potential of RNA-based compounds is far from being fully tapped, as RNA allows for entirely new therapeutic approaches.

SARS-CoV-2 entry at the cell surface facilitated by trypsin

Exogenous trypsin treatment boosts SARS-CoV-2 infection in Vero E6 cells and promotes viral multiplication in cultured cells.

Study reveals seven major determinants of mortality risk for patients with COVD-19 and thoracic cancer

The risk of death for patients with SARS-CoV-2 infection and thoracic cancer is based on seven major determinants, according to research published in the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer.
