Study shows how cells respond to nutrient deprivation

The idea of the cell as a city is a common introduction to biology, conjuring depictions of the cell's organelles as power plants, factories, roads, libraries, warehouses and more.

Rare inherited mutation in TP53 gene predisposes to a wide range of cancers

Rare inherited mutations in the body's master regulator of the DNA repair system – the TP53 gene – can leave people at a higher risk of developing multiple types of cancer over the course of their lives.

Study uncovers virus-specific T cell immunity in recovered COVID-19 and SARS patients

The T cells, along with antibodies, are an integral part of the human immune response against viral infections due to their ability to directly target and kill infected cells.

Umbilical cord blood treats children born with non-cancerous genetic disorders

Researchers at UPMC Children's Hospital of Pittsburgh found that infusing umbilical cord blood -- a readily available source of stem cells -- safely and effectively treated 44 children born with various non-cancerous genetic disorders, including sickle cell, thalassemia, Hunter syndrome, Krabbe disease, metachromatic leukodystrophy (MLD) and an array of immune deficiencies.

PET reveals the existence of inter-organ communication between the heart and kidneys after heart attack

Whole body positron emission tomography (PET) has, for the first time, illustrated the existence of inter-organ communication between the heart and kidneys via the immune system following acute myocardial infarction, or heart attack.

Study estimates the cost-effectiveness of esketamine used for treating depression

A paper authored by researchers from McLean Hospital has determined that esketamine, a nasal spray to treat severe depression, is currently too expensive for widespread use.

The immune system can play a key role in improving recovery from heart attacks

International research collaboration to pioneer the field of immuno-cardiology and investigate ways to harness the power of the immune system to improve recovery from heart attacks will be led at the Perelman School of Medicine at the University of Pennsylvania by Jonathan Epstein, MD, executive vice dean, chief scientific officer and the William Wikoff Smith Professor of Cardiovascular Research.

UTHealth physicians study blood pressure drug's efficiency in improving COVID-19 outcomes

An interventional therapy aimed at improving survival chances and reducing the need for critical care treatment due to COVID-19 is being investigated by physicians at The University of Texas Health Science Center at Houston.

Study reveals how the brain can reliably access stored information despite constant changes

New research, based on earlier results in mice, suggests that our brains are never at rest, even when we are not learning anything about the world around us.

Single dose of tocilizumab improves survival in critically ill COVID-19 patients

Critically ill COVID-19 patients who received a single dose of a drug that calms an overreacting immune system were 45% less likely to die overall, and more likely to be out of the hospital or off a ventilator one month after treatment, compared with those who didn't receive the drug, according to a new study by a team from the University of Michigan.

New technology generates immune response by delivering antigens to APCs in the spleen

Red blood cells do more than shuttle oxygen from our lungs to our organs: they also help the body fight off infections by capturing pathogens on their surfaces, neutralizing them, and presenting them to immune cells in the spleen and liver.

DNA repair tool is tailored to deal with specific type of complex break, study shows

Our cells are constantly dividing, and as they do, the DNA molecule - our genetic code - sometimes gets broken. DNA has twin strands, and a break in both is considered especially dangerous.

Study uncovers new genetic variants linked to type-2 diabetes

After examining the genes of more than 200,000 people all over the world who have type-2 diabetes, researchers from the Perelman School of Medicine at the University of Pennsylvania and the Veterans Health Administration's Corporal Michael J. Crescenz Veterans Affairs Medical Center found hundreds of genetic variants never before linked to the disease.
