Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

Researchers have identified a specific protein complex inside neurons that tags toxic tau fragments for destruction, offering the clearest explanation yet for why certain brain cells survive while ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

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 ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

A new organelle has been discovered in human cells — and scientists call it a "hemifusome." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry ...

Researchers at the Francis Crick Institute and AlveoliX have developed the first human 'lung-on-chip' model using stem cells taken from only one person. These chips simulate breathing motions and lung ...

Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...

Mitochondrial diseases are severe, often untreatable, and they leave human cells unable to grow normally without outside help. A new study published in Nature Metabolism now shows that a single gene ...
