Apoptotic cell death has gained increased importance in neurobiology and ne
uroimmunology. Although apoptosis is per se defined by morphology, it is in
timately linked to a series of molecular events and has a wide array of fun
ctional implications. Here, we summarise the available detection assays for
apoptosis and the current state of research concerning T cell apoptosis in
neuroimmunology and apoptotic neuronal cell death in neurodegeneration and
ischemia. There is a clear therapeutic potential by induction of apoptosis
in inflammatory diseases. Furthermore, protection from apoptotic cell deat
h may be a promising tool in neurodegenerative and ischemic processes. In t
he future, this will necessitate a close cooperation between different fiel
ds of biology research.
