Does ceramide play a role in neural cell apoptosis?
Abstract:
Ceramide is a lipid second messenger, that is generated in response to stimulation of the cell death pathways by a number of ligands binding to surface receptors, growth factor withdrawal, treatment with chemotherapeutic agents, or high doses of ionizing radiation or oxidizing agents. Depending on the target cell, ceramide induces diverse biological responses including apoptosis, cell-cycle arrest, differentiation, and also proliferation. In this review we consider the evidence for its role in apoptosis in cells of the nervous system.
