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.

Mutant protein plays key role in Huntington’s disease

Back in 1993, researchers had discovered that Huntington’s disease is typically caused by a single mutated gene, known as HTT.

Study identifies molecular mechanism by which HSPCs recover after chemotherapy-induced injury

Chemotherapy has a damaging effect on hematopoietic stem and progenitor cells (HSPCs) in bone marrow. However, once chemotherapy ends, HSPCs regenerate, a process that has remained unknown--until now.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

Engineered safety switch reduces CAR-T immunotherapy-related side effects

UNC Lineberger Comprehensive Cancer Center researchers have successfully used an experimental safety switch, incorporated as part of a chimeric antigen receptor T-cell (CAR-T) therapy, a type of immunotherapy, to reduce the severity of treatment side effects that sometimes occur.

SARS-CoV-2 can make itself unrecognizable to immune response by T-killer cells through mutations

The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection. In addition to antibodies, the so-called T-killer cells, are also responsible for detecting viruses in the body and eliminating them.

Research provides new insight into the way cells adapt to fight infection

WEHI researchers have uncovered a process cells use to fight off infection and cancer that could pave the way for precision cancer immunotherapy treatment.

Study reveals new mechanism through which cells build “mini-muscles”

Research teams have revealed how the motor protein, called myosin, which is responsible for causing the contraction of skeletal muscles, also functions in non-muscle cells.

High-fat diet may lead to greater risk of heart attacks

According to a study, consumption of a high-fat diet could trigger a response in the heart, causing growth and resulting in a higher risk of heart attacks.

Researchers develop genetic patch to eliminate problems in hearing cells

They can hear well up to about forty years old, but then suddenly deafness strikes people with DFNA9. The cells of the inner ear can no longer reverse the damage caused by a genetic defect in their DNA.

New technique reveals the tricks that cancer cells use to avoid immunotherapies

By harnessing the immune system against cancer, immunotherapies have revolutionized the way some types of cancer are treated. But most patients--across cancer types--do not respond, and in most cases, scientists are at a loss as to why.

Study describes molecular mechanisms of polar growth in plants

Plants grow in two directions: the shoots of plants grow toward the light to make the best use of it, and the roots grow toward the center of the earth into the soil.
