Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...

Primary immunodeficiencies are genetic disorders that impact on the immune system due to defective function of a variety of genes. Among those molecules are ...

Researchers from the University of California, Los Angeles, have discovered that immune cells known as macrophages remain ...

Our biceps and our brain cells may have more in common than previously thought. New research led by the Lippincott-Schwartz Lab shows that a network of subcellular structures similar to those ...

Among the most promising tools of cancer therapy, engineered immune cells known as chimeric antigen-receptor (CAR) T cells have already transformed the treatment of blood cancers. Yet, despite their ...

Cellular differentiation of stem cells into specialized cells requires many steps, including division, to create more cells; fate determination, which is a commitment to a specific lineage or ...

Modulating miR-21 signaling may work to reduce heart damage in people with pulmonary hypertension (PH), a preclinical study suggests.

In several disease conditions, including infections and cancers, innate immune activation and nutrient scarcity occur together. A study from St. Jude Children's Research Hospital published today in ...
