Recent studies have implicated sphingolipids in a variety of intracellular signaling systems. The finding that a calcium-stimulated ceramide kinase copurifies with neurotransmitter-containing vesicles suggests that ceramide, or one of its metabolites, has a role in neurotransmitter release. As a step

A calcium-dependent ceramide (Cer) kinase was recently detected in human leukemia (HL-60) cells (Kolesnick, R.N., and Hemer, M.R. (1990) J. Biol. Chem. 265, 18803-18808) where it may function in terminating the regulatory effects of Cer, and in synaptic vesicles (Bajjalieh
Apolipoprotein E4 (APOE4) is associated with a greater response to neuroinflammation and the risk of developing late-onset Alzheimer's disease (AD), but the mechanisms for this association are not clear. The activation of calcium-dependent cytosolic phospholipase A2 (cPLA2) is involved in
Lysosomal membrane permeabilization (LMP) is observed under many pathological conditions, leading to cellular dysfunction and death. However, the mechanisms by which lysosomal membranes become leaky in vivo are not clear. Our data demonstrate that LMP occurs in neurons following controlled
