  • Macrophages Chase Neutrophils Away From Wounds to Resolve Inflammation
    Macrophages are best known for their Pac Man-like ability to gobble up cellular debris and pathogens in order to thwart infection. A new study in the Journal of Cell Biology describes how these immune cells also help resolve inflammation by inducing white blood cells called ...More
