Open AccessTRAIL-induced programmed necrosis as a novel approach to eliminate tumor cells
The cytokine TRAIL represents one of the most promising candidates for the apoptotic elimination of tumor cells, either alone or in combination therapies. However, its efficacy is often limited by intrinsic or...

Compartmentalization of TNF-Receptor 1 Signaling: TNF-R1-Associated Caspase-8 Mediates Activation of Acid Sphingomyelinase in Late Endosomes
Tumor necrosis factor-α (TNF-α) is known as a highly pleiotropic cytokine. Stimulation of TNF-receptor 1 (TNF-R1) by TNF-α elicits the transduction of intracellular signals that on the one side promote cell de...

PAF-mediated pulmonary edema: a new role for acid sphingomyelinase and ceramide
Platelet-activating factor (PAF) induces pulmonary edema and has a key role in acute lung injury (ALI). Here we show that PAF induces pulmonary edema through two mechanisms: acid sphingomyelinase (ASM)-depende...

Ceramide as an Activator Lipid of Cathepsin D
We have identified the aspartic protease cathepsin D as a novel intracellular target protein for the lipid second messenger ceramide. Ceramide specifically binds to and induces CTSD proteolytic activity. A-SMa...

Synthesis Studies on Paramagnetic Polystyrene Latex Particles
Radical polymerization in emulsion and in dispersion was applied to incorporate colloidal paramagnetic material into polystyrene latex particles. In emulsion, freshly precipitated magnetite (FeO · Fe2O3 = Fe3O4) ...
