An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls ...

Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play ...

Scientists have transformed enigmatic cell structures, called vaults, into storage units for messenger-RNA molecules made in ...

Metabolism, far from being just a housekeeping function, underlies all changes in cell size and function ...

Scientists at Cedars-Sinai have uncovered an unexpected way the nervous system repairs itself after injury, one that involves support cells acting far from the original damage. Their findings reveal ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as quickly, making people more susceptible to a variety of infections. To try to ...

This study provides valuable data on the role of Hsd17b7, a gene involved in cholesterol biosynthesis, as a potential regulator of mechanosensory hair cell function. The authors used both zebrafish ...

One of the main changes is a loss of the innate immune system's naive T cells, the first line of defense against pathogens, and an increase in the adaptive immune system's memory T cells. This ...

Researchers found that the body’s natural recycling system, the lysosome, plays a vital role in removing the protein that drives premature aging. When this system breaks down, aging speeds up. By ...

Scientists have discovered that boosting lysosome activity helps cells clear progerin, the toxic protein behind premature aging in progeria, offering a potential new way to fight aging-related ...
