The receptor activator of NF-κB (RANK) is especially well studied in the context of bone remodeling, and RANK and its ligand, RANKL, are key molecules in the induction of bone resorbing osteoclasts. We now report that polymorphonuclear neutrophils (PMNs) contain preformed RANK, stored in secretory vesicles and in specific granules. Upon stimulation of PMNs(More)
Monocytes have the potential to differentiate to either macrophages, dendritic cells, or to osteoclasts. The microenvironment, particularly cytokines, directs the monocyte differentiation. Receptors of NFκB (RANK) ligand, tumor necrosis factor (TNF) α, or interleukin- (IL-) 8 have be identified as inducers of osteoclastogenesis, whereas others, such as(More)
Ultrastructural studies of rats or mice treated for 24 hr with a toxic dose (100 mg/kg) of methylglyoxal-bis(guanylhy-drazone) revealed the presence of damaged mitochondria in the crypt cells of the intestinal epithelium. Mitochondria were severely swollen and electron lucent, and appeared to be similar to those observed previously in a variety of cell(More)
