Autophagocytosis
Autophagocytosis (Graecis verbis αὐτόφαγος, digestio sui, et κύτος, cavum, cellula) describit naturalis digestio cellulae ad materias non necessarias vel dysfunctionales delendas, ope lysosomatum. Notio Anglica autophagy[1] anno 1963 inventa est ab Christiano de Duve[2], qui anno 1974 pro operibus de lysosomatibus Praemium Nobelianum physiologiae et medicinae accepit. Ope autophagocytosis intracellularis digestio ordinata et regeneratio partium cellulae fieri potest[3]. Autophagocytosis systema dynamicum consideranda est, non solum cursus degrationis simplicis, sed etiam generationis novarum partium et energiae ad cellulas renovandas, velut homoeostasis.
Genera quattuor descripta sunt: macroautophagocytosis (materiae maioris ut organellorum dysfunctionalium, cursus principalis), microautophagocytosis (materiae minoris cytoplasmaticae), autophagocytosis comite reddita (iter specificum ope complexus HSPA8 (comites hsc70)), crinophagocytosis (fusio directa cum lysosomate, celeris)[4]. Macroautophagocytose ineunte primum ab reticulo endoplasmatico structura sphaerica, omegasoma, formatur; deinde materia destruenda circumcluditur ab phagophora, processus omegasomatis cum coniunctione mitochondriorum[5]; cum formatione membranae duplicis circum materiam vocitatur autophagosoma[6]. Denique fusio inter autophagosoma et lysosoma fit, cum formatione autolysosomatis[7].
In senectute debiliatio autophagocytosis observatur[8].
Vitia autophagocytosis cum morbis hominis coniuncta sunt, ut neurodegenerativis et cancerosis. Nimirum scientia ad inductionem therapeuticam autophagocytosis spectat[9].
Ne confundas autophagocytosis cum:
- Autophagia (Anglice: autophagy), quae autem ad subcategoriam vulneris sui perturbationis psychiatricae, qua vulnera mordendo consumendove corporis oriuntur, refert.
- Lipophagocytosis (Anglice: lipopphagy), quae ad degradationem lipidorum tantum refert.
