Cells throughout the body work together like singers in a choir to keep us healthy, as long as they work in perfect harmony.

Damage to the genetic material of mitochondria—the mitochondrial DNA or mtDNA for short—can lead to diseases such as ...

The electric skin cell signals, which move at glacial pace compared to those in nerve cells, may play a role in initiating healing.

Damage to the mitochondria, the 'power plants' of the cells, contributes to many diseases. Researchers now describe how cells with defective mitochondria activate a special recycling system to ...

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ...

Find out what happens to heart cells in space and how their adaptation could revolutionize heart disease treatment.

Observations of electrical signal propagation across colonies of epithelial cells suggest they may be able to communicate, ...

As cells are infected by microorganisms, they can pre-emptively die to prevent the replication and spreading of the pathogen. Cell death that is associated with the presence of pathogen-associated ...

NK (natural killer) cells are a population of lymphocytes with both innate and adaptive immune features. They produce cytotoxic molecules and can eliminate infected cells or cancer cells.

Finally, proteolytic activity of MMPs can be inhibited by the tissue inhibitors of metalloproteinases, a group of proteins also produced by hepatic stellate cells. Activity grade, which represents ...
