    Notes: Abstract The case of a 38-year-old patient with rapidly progressing motor neuron disease, complicated by major dysfunction of the extrapyramidal system and of vertical gaze is described. Neuropathological examination revealed a degenerative process that severely affected the lower motor neurons, as well as the neurons of the pars compacta of the substantia nigra, the nucleus of Darkschewitsch, the nucleus interstitialis of Cajal, the colliculi superiores, and the pallidum. The long tracts were unaffected at all levels of the brain stem and spinal cord. There was no convincing evidence for the presence of a multiple system atrophy or progressive supranuclear palsy; the results rather revealed a pattern of vulnerability characteristic of a variant of motor neuron disease.

    Description / Table of Contents: Abstract Apoptosis, or programmed cell death, is a physiological cell suicide program mainly leading to selective elimination of useless cells. This mechanism is important for the homeostasis of the immune system and presumably plays a two-sided role in the pathogenesis of multiple sclerosis (MS). On the one hand, evidence has been provided that impaired apoptosis might result in increased numbers or persistence of activated myelin-specific T cells, thus inducing the pathophysiologic processes in MS. On the other hand, local tissue damage might involve apoptosis of glial and neuronal cells and lead to the clinical symptoms. Here, an overview is presented on the current knowledge of the role of apoptosis in the pathogenesis of MS, and implications for related therapeutic strategies are discussed.
    Notes: Zusammenfassung Apoptose, auch programmierter Zelltod genannt, stellt einen physiologischen Prozess zur selektiven Eliminierung vor allem von unerwünschten körpereigenen Zellen dar. Dieser für die Homöostase des Immunsystems wichtige Mechanismus nimmt wahrscheinlich eine ambivalente Schlüsselrolle in der Ätiopathogenese der multiplen Sklerose (MS) ein. So existieren Hinweise dafür, dass bei der MS eine eingeschränkte Apoptose zur pathologischen Existenz und Persistenz aktivierter myelinspezifischer T-Zellen führt, die wiederum für die charakteristische intrazerebrale Entzündung verantwortlich gemacht werden. Gleichzeitig deuten aktuelle Arbeiten aber darauf hin, dass auf der Endstrecke der entzündlichen Reaktion der apoptotische Untergang von Glia- und evtl. auch Nervenzellen zur Gewebeschädigung und somit entscheidend zur klinischen Symptomatik beitragen. Ziel dieser Übersicht ist die Zusammenstellung der bislang gewonnenen Erkenntnisse zur Bedeutung von Apoptose für die Pathogenese der MS und eines Ausblicks auf mögliche apoptoseorientierte Therapiestrategien.
