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.

Study explores COVID-19 transmission risk during school bus transportation

Although in-school transmission of COVID-19 among K-12 students is low when safeguards are in place, the risk of acquiring COVID-19 during school bus transportation is unclear. A study published in the Journal of School Health reports on the bus transport experience of an independent school in Virginia.

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.

$Cognitive decline increases future fracture risk in women$

Cognitive decline increases future fracture risk in women

Researchers led by the Garvan Institute of Medical Research have discovered a link between cognitive decline and a faster rate of bone loss, and found that cognitive decline over five years increased future fracture risk in women. The association between cognitive decline and bone loss was weaker in men.

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.
