The toxic reactive aldehyde lipid peroxidation byproduct 4-hydroxy-2-nonenal (HNE) is thought to be a major contributor to oxidant stress-mediated cell injury. HNE induced apoptosis in RAW 264.7 murine macrophage cells in a dose-dependent manner within 6-8 h after exposure. Expression of the antiapoptotic protein Bcl-2 in stably transfected RAW 264.7 cells(More)
The sphingolipid sphingosine-1-phosphate (S1P) is an important regulator of immune cell functions in vivo. Besides recruiting lymphocytes to blood and lymph, it may promote immune cell survival and proliferation, but also interferes with their activation. Hereby, S1P may act as an intracellular second messenger or cofactor or, upon being secreted from(More)
