Scientists at Cincinnati Children's have identified how certain immune cells are molecularly programmed to respond faster when the body encounters a familiar threat, shedding light on immune memory ...

Some of the signs of ageing in human cells originate in the cell nucleus, because the packaged form of DNA changes with age. This has now been demonstrated by PSI researchers. It means that older cell ...

Inflammation hasto fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this ...

A new study traces the molecular pathway connecting the gut immune system to the brain during a parasitic infection, explaining how the immune system triggers a loss of appetite.

Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new improved ways of creating new tissues, organs, nerves and bones. Dr Amy ...

Rockefeller scientists uncovered how hair follicle stem cells can switch from growing hair to repairing skin when nutrients run low. The key lies in serine, an amino acid that activates a stress ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...
