    Novel C1q receptor-mediated signaling controls neural stem cell behavior and neurorepair

    Francisca Benavente et al.
    Complement C1q directly drives the behavior of human neural stem cells via a classical receptor signaling mechanism modulating their capacity for functional integration in vivo.

    Neuroepithelial Stem Cells: The many roles of C1q

    Mark Noble, Christoph Pröschel
    The ability of C1q to bind to a variety of receptors has implications for signaling biology, spinal cord injury and, possibly, the evolution of the complement system.

    Dpp dependent Hematopoietic stem cells give rise to Hh dependent blood progenitors in larval lymph gland of Drosophila

    Nidhi Sharma Dey et al.
    Identification of Hematopoietic stem cells (HSCs) in the genetically amenable organism Drosophila melanogaster paves the path to address HSC biology, both in normal and pathophysiological conditions.

    Fast retrieval and autonomous regulation of single spontaneously recycling synaptic vesicles

    Jeremy Leitz, Ege T Kavalali
    Spontaneous fusion of vesicles at synapses is regulated independently of fusion triggered by action potentials, adding to evidence that the two types of fusion have distinct functions.

    Learning protein constitutive motifs from sequence data

    Jérôme Tubiana et al.
    A new machine-learning toolbox unveils coevolutionary protein motifs related to structure, function, and phylogeny from sequence information only.

    Polo-like kinase acts as a molecular timer that safeguards the asymmetric fate of spindle microtubule-organizing centers

    Laura Matellán et al.
    Molecular and cell biology analyses reveal novel roles of Polo-like kinases in establishing non-random segregation patterns of spindle-associated microtubule-organizing centers during mitosis, a phenomenon linked with replicative cell aging.

    The tricuspid valve also maladapts as shown in sheep with biventricular heart failure

    William D Meador et al.
    Demonstrating the tricuspid valve maladapts is critical, and understanding its regurgitation may aid in developing better treatment strategies.

    Extended low-resolution structure of a Leptospira antigen offers high bactericidal antibody accessibility amenable to vaccine design

    Ching-Lin Hsieh et al.
    The antibody accessibility of the leptospiral surface protein, LigB, provides a guide for the rational design of improved recombinant chimeric vaccine antigens displayed on a single domain scaffold.

    Soluble collectin-12 mediates C3-independent docking of properdin that activates the alternative pathway of complement

    Jie Zhang et al.
    A systematic set of experiments reveals how properdin specifically directs AP activation independently of primary C3 deposition additionally as an alternative convertase stabilizer, thus revising immune machinery of complement activation.
