All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

A quick revision guide covering key concepts, biomolecules, cell organelles, and essential NEET-style MCQs to boost exam ...

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the ‘dark genome’ that are responsible for controlling how cells sense and respond to the ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular ...

Hormones coordinate different body functions by carrying messages through the bloodstream to target cells and tissues. Hormonal imbalances occur through inadequate or excess hormone synthesis, which ...

No one has yet created a fully functioning artificial cell. But a research team at Aarhus University has taken a step in that ...

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 in Cell, ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...
