Emerging studies indicate that intracellular eukaryotic ceramide species directly activate cathepsin B (CatB), a lysosomal-cysteine-protease, in the cytoplasm of osteoclast precursors (OCPs) leading to elevated RANKL-mediated osteoclastogenesis and inflammatory osteolysis. However, the possible impact of CatB on osteoclastogenesis elevated by
