期刊介绍： Autophagy is a peer-reviewed journal that publishes research on autophagic processes, including the lysosome/vacuole dependent degradation of intracellular material. It aims to be the premier journal in the field and covers various connections between autophagy and human health and disease, such as cancer, neurodegeneration, aging, diabetes, myopathies, and heart disease. Autophagy is interested in all experimental systems, from yeast to human. Suggestions for specialized topics are welcome. The journal accepts the following types of articles: Original research, Reviews, Technical papers, Brief Reports, Addenda, Letters to the Editor, Commentaries and Views, and Articles on science and art. Autophagy is abstracted/indexed in Adis International Ltd (Reactions Weekly), EBSCOhost (Biological Abstracts), Elsevier BV (EMBASE and Scopus), PubMed, Biological Abstracts, Science Citation Index Expanded, Web of Science, and MEDLINE.
