Injecting mice with pulmonary endothelial cells can reverse symptoms of emphysema

Researchers at Weill Cornell Medicine and NewYork-Presbyterian in New York have discovered that injecting mice with pulmonary endothelial cells-the cells that line the walls of blood vessels in the lung-can reverse the symptoms of emphysema.

SARS-CoV-2 can be transmitted by cats

Researchers in The Netherlands have warned that domestic cats may play a role in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Oral targeted therapy found to be an effective treatment option for high-risk hairy cell leukemia

The oral targeted therapy drug ibrutinib is an effective treatment option for high-risk hairy cell leukemia, according to a new study conducted by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Researchers use information theory to monitor resistance mechanisms to targeted cancer therapy

One of the major challenges in modern cancer therapy is the adaptive response of cancer cells to targeted therapies: initially, these therapies are very often effective, then adaptive resistance occurs, allowing the tumor cells to proliferate again.

U.S. sees sharp decrease in life expectancy largely due to COVID-19 pandemic, CDC says

New preliminary data from the United States Centers for Disease Control and Prevention (CDC) suggests that average life expectancy in the United States fell by 1.5 years over 2020.

Scientists identify gut microbiota dysbiosis as a potential risk factor for long COVID

A study in Norway has recently highlighted a significant association between gut microbiota alteration and persistent respiratory dysfunction in coronavirus disease 2019 (COVID-19) patients.

Intestinal organoids demonstrate variability in SARS-CoV-2 susceptibility

Three-dimensional organoid structures grown in the lab allow deeper, almost in situ investigation of a biological system, without the use of living animals. In a paper recently uploaded to the preprint server bioRxiv*, organoids generated from human specimens are utilized to investigate the way in which SARS-CoV-2 interacts with the numerous cells of the intestinal epithelium, finding great heterogeneity in the susceptibility of the organoids and the cells within to infection.

Study examines the host and viral factors that drive SARS-CoV-2 evolution

In a new paper recently uploaded to the preprint server bioRxiv*, two clinical isolates of SARS-CoV-2 are monitored by whole genome sequencing as they are passaged through several generations of Vero cells or human-derived primary nasal epithelial cells (PNEC), allowing direct observation of the occurrence of virus enhancing mutations and the way in which host cell factors shape virus evolution.

Study associates feelings of discrimination and low status with long COVID-19 symptoms

A recent study, released as a preprint on the medRxiv* server, examines the correlation of these symptoms with the patient’s socioeconomic status (SES) and perception of social discrimination, along with other social factors. The researchers found that the first two factors are associated strongly with long-term symptoms of COVID-19.

How to run a COVID-19 vaccination campaign: lessons from other infectious outbreaks

A new paper, available on the medRxiv* preprint server, presents lessons learned from the implementation of three adult vaccine programs in low- and middle-income countries (LMICs) in Africa and South America.

COVIDcast API: An open repository of real-time COVID-19 indicators

A new preprint available on the medRxiv* server reports the utility of the COVIDcast API, a database of all COVID-19 indicators that are constantly being updated, dating from April 2020.

Protein markers in chronic lymphocytic leukemia may help determine patients' prognoses

Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world. New research published in the Journal of Leukocyte Biology reveals that certain protein markers may indicate which patients have stable forms of CLL and which have more aggressive types.

Human coronaviruses need organic materials to transfer efficiently between surfaces

This study, published in the journal Viruses, indicated that human coronaviruses do not transfer effectively from contaminated hands to contact surfaces without the presence of any organic material.

Human tissue xenografts in murine models for the study of SARS-CoV-2

Severe COVID-19 is associated with massive dysregulation of the host immune response, resulting in inflammation and the condition known as a cytokine storm. For the most part, however, the virus is barely noticeable or only mild among the young and healthy, suggesting that the route and intensity of an immune response could determine the severity of the disease.

Scientists explore susceptibility of different animals to SARS-CoV-2 infection

A team of researchers at the Institute of Infectious Diseases (IFIK) at the University of Bern and the Institute of Virology and Immunology (IVI) has utilized a unique collection of advanced cell culture models of cells lining the airways from various domesticated and wildlife animals. This way, the team can determine which animals are susceptible to SARS-CoV-2 infection.

MET amplification identified as a potentially actionable driver for non-small cell lung cancer

A study led by D. Ross Camidge, MD, PhD, director of thoracic oncology at the University of Colorado School of Medicine and CU Cancer Center member, has helped to define MET amplification as a rare but potentially actionable driver for non-small cell lung cancer (NSCLC).
