Abstract excerpt
Over 1 billion monocytes are produced daily, with a small percentage differentiating into macrophages, suggesting that excess monocytes are deleted through a tightly regulated process. Although the in vivo mechanism governing monocyte/macrophage homeostasis is unknown, deletion of monocytes in culture is mediated by the Fas death pathway and is blocked by M-CSF. To determine the in vivo significance of Fas in...
