Special Issue Information

Dear Colleagues,

Autophagy is a "self-digestion" process conserved in eukaryotic cells. During autophagy, intracellular materials (cargo), such as dysfunctional organelles, protein aggregates, lipid droplets, and microbial pathogens, are delivered to the lysosome to be degraded. Based on the transportation method, autophagy can be classified into three main types: macroautophagy, which is the most extensively studied; chaperone-mediated autophagy; and microautophagy.

Autophagy plays a critical role in cellular homeostasis and is associated with the progression of various diseases, such as cancer and neurodegenerative disorders. It primarily supports cell survival, whereby autophagic degradation generates small molecules for biosynthesis and energy production. Recent studies have shown that autophagy promotes cell growth, which refers to an increase in cell numbers, and is regulated by cell proliferation and cell survival.

This Special Issue aims to collect original research and review articles on the underlying mechanisms of the autophagy regulation of cell survival and growth in various eukaryotic cells.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Autophagy plays a homeostatic role in regulating cellular metabolism by degrading unwanted intracellular materials and acts as a host defense mechanism by eliminating infecting pathogens, such as viruses. Upon viral infection, host cells often activate retinoic acid-inducible gene I (RIG-I)-like receptor (RLR) signaling to induce the transcription of type I interferons, thus establishing the first line of the innate antiviral response. In recent years, numerous studies have shown that virus-mediated autophagy activation may benefit viral replication through different actions on host cellular processes, including the modulation of RLR-mediated innate immunity. Here, an overview of the functional molecules and regulatory mechanism of the RLR antiviral immune response as well as autophagy is presented. Moreover, a summary of the current knowledge on the biological role of autophagy in regulating RLR antiviral signaling is provided. The molecular mechanisms underlying the crosstalk between autophagy and RLR innate immunity are also discussed. Full article
