Control of cell population sizes: When is enough enough?

Researchers at the University of Basel have uncovered a cell-intrinsic mechanism, that controls the appropriate number of T cells in the organism and thus ensures that the immune system functions properly. This mechanism ...

Replication protein A and WAS protein partner to fix damaged DNA

DNA replication and repair happens thousands of times a day in the human body and most of the time, people don't notice when things go wrong thanks to the work of Replication protein A (RPA), the "guardian of the genome." ...

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

Having stressed out ancestors improves immune response to stress

Having ancestors who were frequently exposed to stressors can improve one's own immune response to stressors, according to Penn State researchers. The results suggest that family history should be considered to predict or ...

Scientists see human immune response in the fruit fly

Washington State University researchers have seen how both humans and fruit flies deploy a protein that a plays a critical role in their immune responses to invading bacteria. The discovery gives scientists evolutionary insight ...
