Liposome-encapsulated dichloromethylene diphosphonate induces macrophage apoptosis in vivo and in vitro.

abstract：:Alveolar macrophages from chronic obstructive pulmonary disease patients and cigarette smokers are deficient in their ability to phagocytose apoptotic bronchial epithelial cells (efferocytosis). We hypothesized that the defect is mediated via inhibition of sphingosine kinases and/or their subcellular mislocalization i...
