Immune system is already active before birth

Researchers have found that neutrophils, white blood cells, are present in many tissues during embryonic development, performing functions similar to adult neutrophils. This discovery suggests that embryonic neutrophils may have roles in tissue development and homeostasis in addition to immune defense.

Cellular recycling: A molecular switch directs the cargo

A team at the University of Basel has identified a molecular switch that controls the sorting of recyclable cargo into transport vesicles. The small protein ARF-1 ensures efficient loading and return of cargo to the cell surface. This process, known as 'kiss-and-run,' allows cells to reuse receptors and transport proteins, and disrupti...
