New research on vitamin D and respiratory infections important for risk groups

Earlier studies have shown that supplementary vitamin D seems to provide a certain degree of protection against respiratory infections. A new study involving researchers from Karolinska Institutet has now made the most comprehensive synthesis to date of this connection. The study, which is published in the journal Lancet Diabetes & […]

T cells recognize recent SARS-CoV-2 variants

When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective. To investigate this possibility, researchers from the National Institute of Allergy and Infectious […]

Researchers craft AI-based tool that detects bipolar disorder at earlier stages

Many people with early-stage or first-episode bipolar disorder have cognitive deficits, such as issues with visual processing and spatial memory, but those deficits are often so subtle that the disorder can go undiagnosed for years. That could change thanks to researchers at the University of Alberta who have created a […]

Study Illuminates the Molecular Details of Lung Development

Researchers at the Perelman School of Medicine at the University of Pennsylvania have produced a detailed molecular atlas of lung development, which is expected to be a fundamental reference in future studies of mammalian biology and of new treatments for diseases, such as COVID-19, that affect the lungs. The researchers, […]

Study identifies potential biomarkers for cognitive struggles after surgery

But up to half of older patients undergoing surgery face a lesser-known but similarly formidable cognitive challenge: postoperative delirium, a condition triggered by a surgery that requires anaesthesia and whose trademarks are confusion, disturbed mental faculties, loss of orientation and anxiety. In the worst cases, postoperative delirium leads to extended […]

Study shows loss of gene function is causal to congenital heart disease

A team of researchers co-led by Michael Frohman of Stony Brook University has identified an important cause of congenital heart disease. The researchers discovered that certain loss of functions in the PLD1 (phospholipase D1) gene causes congenital right-sided cardiac valve defects and neonatal cardiomyopathy. The findings are detailed in a paper in […]

New anticancer drug targets low-oxygen environment of solid tumors

Researchers are perfecting a new generation of anticancer drugs that will be able to specifically target the low-oxygen environment of solid tumors. So far, the new drug has been tested in preliminary experiments with human tumors transplanted into otherwise healthy adult mice. Low oxygen levels among the densely packed cells […]

Prior COVID infection primes immune response to one dose of Pfizer/BioNTech vaccine

People previously infected with SARS-CoV-2 show significantly higher T cell and antibody responses following a single dose of Pfizer/BioNTech vaccine compared with uninfected individuals, a collaborative study involving University of Liverpool researchers has found, While both groups show robust immune responses after one dose, the higher response experienced by previously […]

Engineered immune cells deliver anticancer signal, prevent cancer from spreading

Scientists have genetically engineered immune cells, called myeloid cells, to precisely deliver an anticancer signal to organs where cancer may spread. In a study of mice, treatment with the engineered cells shrank tumors and prevented the cancer from spreading to other parts of the body. The study, led by scientists […]

DNA damage “hot spots” discovered within neurons

Researchers at the National Institutes of Health (NIH) have discovered specific regions within the DNA of neurons that accumulate a certain type of damage (called single-strand breaks or SSBs). This accumulation of SSBs appears to be unique to neurons, and it challenges what is generally understood about the cause of […]

Research Group Identifies Potential Therapeutic Target for Lupus

A recent study published in JCI found that a neutrophil’s endoplasmic reticulum, the organelle that normally makes proteins in the cell, becomes stressed in the autoimmune disorder lupus. This stress activates a molecule called IRE1α, which appears to play a critical role in lupus pathogenesis in mice. A multidisciplinary research group at the University […]

Gene changes linked to severe repetitive behaviors

Graybiel lab identifies genes linked to abnormal repetitive behaviors often seen in models of addiction and schizophrenia. Extreme repetitive behaviors such as hand-flapping, body-rocking, skin-picking, and sniffing are common to a number of brain disorders including autism, schizophrenia, Huntington’s disease, and drug addiction. These behaviors, termed stereotypies, are also apparent in animal models […]
