Probleme Der Cellulren Autophagie: Morphologische, Enzymcytochemische Und Quantitative Untersuchungen An Normalen Und Alterierte
Delivery time: 8-12 business days (International)
Als cellulre Autophagie bezeichnet man einen Vorgang, bei dem innerhalb einer Zelle umschriebene Portionen des Cytoplasmas durch Membranen abge grenzt und damit in ein eigenes Kompartiment verlagert werden, in welchem dann das segregierte Material intracellulr verdaut, also in kleinere Einheiten aufgespalten wird. Der Terminus Autophagie wurde auf der cellulren Ebene erstmals von Brachet (1961) im Zusammenhang mit Stoffwechselumstellungen bei enucleier ten Amben verwandt. Von morphologischen Befunden ausgehend hatte aber schon vorher Altmann (1956) die Konzeption entwickelt, da Anteile des Cyto plasmas unter den Erscheinungen der umschriebenen Coagulation ausgegliedert und abgebaut werden knnen. Elektronenmikroskopische Untersuchungen (Hru ban et a1., 1962; Ashford u. Porter, 1962) und die Integration solcher Phno mene in das Lysosomenkonzept (Novikoff u. Essner, 1962; de Duve, 1963a, b; Ericsson et a1., 1965; de Duve u. Wattiaux, 1966) haben diese Vorstellung besttigt und eine Flle von Keimtnissen zutage gefrdert, die zuletzt von Ericsson (1969c) zusammenfassend dargestellt worden sind.
