T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on ...

Cancer-fighting T cells do not simply "run out of energy." They are molecularly reprogrammed. For years, mitochondrial ...

Researchers at Texas A&M Health have identified a molecular mechanism that increases cholesterol levels inside prostate ...

In preliminary experiments with mice and lab-grown cells, Johns Hopkins Kimmel Cancer Center scientists have found that a protein-signaling process accelerates the work of the gene most frequently ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism. The study suggests that nitric oxide, a tiny signaling molecule normally ...

Researchers have identified a specific hormone produced by pancreatic beta cells as a direct driver of obesity-linked ...

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies. We’re used to thinking of the brain as an ...
