  Evaluation Summary:

  This paper is of broad interest to readers who are interested in understanding cell migration and the cytoskeleton. It characterizes new behaviors of actin-based stress fibers in vivo during collective cell migration, and provides important observations that contribute to our fundamental understanding of these structures. The use of high-resolution live imaging in combination with Drosophila genetics and pharmacological inhibitors provides compelling data that supports the major claims of the paper.

  Evaluation Summary:

  The manuscript provides novel data to support the role of CNP (C Type Natriuretic peptide) in the proliferation and stimulation of growth plate chondrocytes for development of bone. The methods used are innovative and the data provided support the overall hypothesis of the study presented in the paper, which should be of broad interest to bone and cartilage biologists.

• Curated by eLife

  Evaluation Summary:

  Initial insights were provided by yeast genetic experiments into the mechanisms of starvation-induced autophagy. Since malfunctioning of this process is involved in numerous diseases, there is a need for further understanding the role and regulation of autophagy in different physiological settings. This work convincingly shows that a newly identified phosphatase controls basal levels of autophagy via regulation of phospho-acinus levels and reveals how cadmium intoxication triggers a neuroprotective autophagic response in the popular animal model Drosophila.

  Evaluation Summary:

  This paper addresses the mechanisms regulating cytoskeletal changes mediating neuronal branching and axon growth. The authors assess the role of the scaffolding protein giant ankyrin B in cortical neuron differentiation and present strong data implicating ankyrin B functions with the cell adhesion molecule/Sema3A receptor complex and an actin severing protein. With a better explanation of the function of ankyrin B in the Sema3A signaling pathway, this manuscript will be of interest to cell biologists and developmental neurobiologists working to uncover the biological mechanisms of early circuit development, and how these mechanisms relate to autism spectrum disorders.

Initial ciliary assembly in Chlamydomonas requires Arp2/3 complex–dependent endocytosis

• Curated by eLife

  Evaluation Summary:

  This manuscript addresses the role of the Arp2/3 complex in endocytic retrieval of ciliary precursors from the plasma membrane for use in assembly of Chlamydomonas cilia, a topic of broad interest to cell biologists. The manuscript can serve as basis for future research addressing whether Arp2/3 affects cilium biogenesis solely via endocytic retrieval or through additional mechanisms, and whether these findings apply to species other than Chlamydomonas.

  Evaluation Summary:

  Proteins that form pores in biological membranes are found in diverse contexts, including pathogenic toxins that help infect or lyse target cells and organelles. The study by Nadeem et al. reports on the properties of an α-pore-forming toxin, MakA, produced by the human pathogen, V. cholerae. The study is a remarkable example of a pH-induced structural mechanism of membrane remodeling. The insights reported here will be of interest to a wide range of scientists studying host-pathogen interactions, membrane remodeling, and macromolecular structure.

• Curated by eLife

  Evaluation Summary:

  Endosome maturation in animal cells has been challenging to characterize by microscopy because the fluorescence patterns are complex and dynamic. This study uses acute ionophore treatment to generate enlarged early endosomes, whose behavior and maturation can then be readily tracked. The results offer new insights into several phenomena, including the regulation of endosomal acidification during the maturation process.
