Sphingolipid ceramide has emerged as a lipid messenger of cell functio
ns including differentiation and apoptosis. Diverse kinds of stresses
(ultraviolet, irradiation, heat shock and hypoxia) and biological fact
ors (TNF-alpha, IFN-gamma and Fas antibody) require ceramide generatio
n to execute apoptosis. The review summarises the diversity and comple
xity of up- and downstream of ceramide signalling in apoptosis and cli
nical implications of ceramide induced apoptosis. CELL SIGNAL 10;10:68
