“Paralyzed” immune cells can be reactivated by drugs in IDH-mutant gliomas

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

New method can enable early detection and treatment of cerebral aneurysms

Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'.

Highly efficient method to identify the genetic “switches” that control gene expression

Scientists have created a high-throughput method to help explain and regulate gene expression for the treatment of diseases like beta-thalassemia and sickle cell disease.

Macrophages perform necessary damage-control function following tissue injury

Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

POSTECH researchers bioengineer a novel drug-delivering adhesive patch platform

Blood vessels deliver nutrients and oxygen to each organ in our body. They are difficult to completely restore to their original conditions once damaged by myocardial infarction or severe ischemic diseases. This is because various angiogenic growth factors must be applied sequentially in order to restore the vascular structure.

New stem cell therapy shows promise to help patients with non-healing diabetic foot ulcers

According to the results of a phase 1 clinical trial just published in STEM CELLS Translational Medicine, a new stem cell therapy shows promise of making diabetes-related amputations a thing of the past.

Key molecule determines the pathogenesis of lupus

A new research work, published in JCI, has discovered that the endoplasmic reticulum of a neutrophil becomes stressed in the autoimmune disorder lupus.

New genetic evidence points to novel therapies for “silent” stroke

According to a study, researchers have discovered new genetic clues in individuals who had experienced small but often apparently “silent” strokes.

Nutritional supplement may reduce the risk of strokes caused by a rare genetic disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered that a widely used nutritional supplement may significantly reduce the risk of fatal strokes caused by a rare genetic disorder.

Genetic flaw shows promise for treating eye disease

A genetic flaw may hold the key to delay or prevent the onset of a serious eye disorder that can result in blindness and vision loss.

Catechin-type flavonoid compounds in tea relax blood vessels by activating ion channel proteins

A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall.

Research links blood-clotting protein with CNS B-cell lymphoma growth

In people with central nervous system (CNS) lymphoma, cancerous B cells--a type of white blood cell--accumulate to form tumors in the brain or spinal cord, often in close proximity to blood vessels.

Study uncovers how cells actively seek information to make better collective decisions

Cells, like humans, cast votes to make decisions as a group. But how do they know what to vote for? Researchers at the Francis Crick Institute and King's College London have uncovered how cells actively seek information in order to make faster and better collective decisions to coordinate the growth of new blood vessels. This provides a new basis for understanding intelligence in cells.

AI analyzes tissue scans to identify cancer patients at risk of hyperprogressive disease

Researchers at Case Western Reserve University, using artificial intelligence (AI) to analyze simple tissue scans, say they have discovered biomarkers that could tell doctors which lung cancer patients might actually get worse from immunotherapy.

Study shows how stem cell niche maintain their self-renewal capacity

A typical trait of all stem cells is their potential to renew on their own; however, scientists are unsure about how this ability is sustaining throughout life.

Study shows two phases of wall restructuring after an aneurysm forms

Hitting a pothole on the road in just the wrong way might create a bulge on the tire, a weakened spot that will almost certainly lead to an eventual flat tire. But what if that tire could immediately begin reknitting its rubber, reinforcing the bulge and preventing it from bursting?
