During the past several years, ceramide has emerged as an important second messenger triggering cell responses including proliferation, differentiation, growth arrest and apoptosis. This thesis has focused on the regulation of neutral ceramidase which critically determines, in concert with ceramide generating sphingomyelinases, the intracellular ceramide levels. In the first part it is reported that besides a rapid and transient increase in neutral sphingomyelinase activity a second delayed peak of activation occurs after hours of IL-1beta treatment. This second phase of activation is first detectable after 2 h of treatment, and steadily increases over the next two hours reaching maximal values after 4 h. In parallel, a pronounced increase ...
