Book Description
Non-canonical Autophagy: Mechanisms and Pathophysiological Implications outlines the differences between ‘canonical’ and ‘non-canonical’ forms of autophagy, highlighting the discoveries concerning the molecular mechanisms underlying these unconventional forms of autophagy and the advancements in pathophysiological features of ‘non-canonical’ autophagy. The book discusses all forms of ‘non-canonical’ autophagy and the complexity of autophagy-dependent cell death. Readers will gain a better understanding of mechanisms underlying ‘non-canonical’ autophagy so that they can interpret the biological effects of autophagy correctly and identify reliable, novel and effective treatment strategies. Presents the most advanced information surrounding the molecular mechanisms underlying non-canonical autophagy Outlines the increasing evidence regarding the involvement of non-canonical autophagy in multiple physiological and pathological processes Discusses the therapeutic potential of autophagy modulators and the obstacles that have limited their development

Book Description
Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.

Book Description
The canonical autophagy pathway has primarily been described as a degradative mechanism, which clears the cell of old damaged organelles, protein aggregates and pathogens. Central to the pathway is the de novo formation of a vesicle structure called the autophagosome, which fuses with lysosomes to degrade its content. The Atg8a/MAP1-LC3 protein family is essential for the formation of the autophagosome, and Atg8a mutations result in a variety of defects related to decreased autophagic function. Recently, we have observed a phenotype in Atg8a mutant Drosophila that is consistent with secretory defects of the peptide hormone Bursicon, which is responsible for wing expansion and cuticle hardening upon eclosion. This observation is in accordance with other recent findings which show that components of the autophagy pathway are also involved in the secretion of bioactive molecules. However, the intersection of autophagy and secretory pathways is not yet fully understood. Here, we show that along with Bursicon two additional peptide hormones are differentially secreted and show impaired hemolymph profiles when autophagic function is lowered in the fly nervous system. This includes the release of the pigment dispersing factor (PDF, circadian cycle) and the mesencephalic astrocyte-derived neurotrophic factor (dMANF, stress response), which is highlighted by the aberrant sleep-circadian behaviors (PDF) and trauma-mediated sensitivity (MANF) associated with Atg8a1 mutant flies. Based on the Bursicon wing phenotype, we conducted a secretion-based screen using the GAL4/UAS-dsRNAi knockdown system and identified Atg8a and other autophagy components involved with organelle initiation and membrane expansion that show impaired Bursicon release upon knockdown. Furthermore, this did not include genes involved with selective autophagy (aggrephagy) or endosomal-lysosomal trafficking. Findings from this research will have broad implications toward understanding complex secretory defects and the intersection of autophagy with other vesicle trafficking pathways.
