    Autophagy is a cellular degradation and recycling process with complex roles in health and disease and emerging relevance to translational research. In this issue, we launch a Series of commissioned articles that will discuss recent advances and outstanding questions driving this rapidly expanding and diverse field.

Research Highlights

    Inflammation and reactive oxygen species (ROS) production after central nervous system injury are thought to enhance tissue damage and hamper neuronal regeneration. Evidence now suggests that NADPH2 oxidase delivery from macrophages to injured neurons through extracellular vesicles, promotes ROS signalling and axon recovery.

    Cytoplasmic flows are essential for various cellular processes. However, tools to manipulate these flows within cells are still lacking. Now research shows that an optical tool allows for control of cytoplasmic flows and can be used as a subcellular rheometer.

    Exosomes are heterogeneous, nanoscale vesicles that mediate cellular communication. A study now leverages a size separation strategy to identify sub-classes of nanoparticles, revealing a subtype without an encapsulating membrane and variation in vesicle cargo, suggesting that size is not the only driver of heterogeneity.

    N6-methyladenosine (m6A) mRNA modification influences mRNA fate by stimulating recruitment of m6A reader proteins. A previously unappreciated class of m6A reader proteins is now shown to use a common RNA-binding domain and flanking regions to selectively bind m6A-containing mRNAs, increasing their translation and stability.

    In this Review Article, Klionsky and co-authors discuss selective autophagy pathways that degrade unwanted cytosolic components and organelles, and how these pathways require ligand receptors and scaffold proteins for cargo specificity.

    Autophagy and cancer: In this Review, Galluzzi and colleagues discuss the cellular and molecular mechanisms whereby autophagy functions in multiple aspects of malignant disease, including cancer initiation, progression and responses to therapy.

    van Haren et al. develop a tool to rapidly dissociate proteins from the growing end of microtubules through photo-induced disassembly of end-binding protein 1 (EB1), and find that this reduces microtubule growth and alters cell migration.

    Hawk et al. show that RIPK1 activation during extracellular matrix detachment induces mitophagy through mitochondrial phosphatase PGAM5 to increase reactive oxygen species and non-apoptotic cell death, and that antagonizing RIPK1/PGAM5 enhances tumour formation.

    Huang et al. identify IGF2BPs as an additional class of N6-methyladenosine (m6A) reader proteins. They find that IGF2BPs selectively bind to m6A-containing mRNAs and promote their stability.
