    T cell deficiency precipitates antibody evasion and emergence of neurovirulent polyomavirus

    Matthew D Lauver, Ge Jin ... Aron E Lukacher
    Loss of T cell control during persistent polyomavirus infection, in the setting of a limited antiviral antibody response, facilitates emergence of antibody-escape viruses carrying the potential for neurovirulence.

    CELF RNA binding proteins promote axon regeneration in C. elegans and mammals through alternative splicing of Syntaxins

    Lizhen Chen, Zhijie Liu ... Yishi Jin
    Genetics and genomics approaches reveal a conserved post-transcriptional regulatory mechanism that promotes adult axon regeneration from worm to mammals.

    Multiscale analysis of single and double maternal-zygotic Myh9 and Myh10 mutants during mouse preimplantation development

    Markus Frederik Schliffka, Anna Francesca Tortorelli ... Jean-Léon Maître
    During mouse preimplantation development, the complete loss of actomyosin contractility abolishes cytokinesis but not apico-basal polarisation, lineage specification, or fluid accumulation, which are the critical steps to the formation of the blastocyst.

    RNA-binding deficient TDP-43 drives cognitive decline in a mouse model of TDP-43 proteinopathy

    Julie C Necarsulmer, Jeremy M Simon ... Todd J Cohen
    Impairing TDP-43 RNA-binding capacity through a single acetylation-mimic mutation alters TDP-43 function and recapitulates biochemical, molecular, and behavioral features of sporadic TDP-43 proteinopathies, thus providing opportunities for new research into pathogenic mechanisms and therapeutic interventions.

    Dynamics of nevus development implicate cell cooperation in the growth arrest of transformed melanocytes

    Rolando Ruiz-Vega, Chi-Fen Chen ... Arthur D Lander
    Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.

    Human HPSE2 gene transfer ameliorates bladder pathophysiology in a mutant mouse model of urofacial syndrome

    Filipa M Lopes, Celine Grenier ... Neil A Roberts
    Proof of concept that viral vector-mediated gene transfer improves bladder function in a preclinical model of an inherited early-onset lower urinary tract disease.

    EphrinB2 knockdown in cervical spinal cord preserves diaphragm innervation in a mutant SOD1 mouse model of ALS

    Mark W Urban, Brittany A Charsar ... Angelo C Lepore
    In the SOD1G93A mouse model of amyotrophic lateral sclerosis (ALS), expression of transmembrane signaling molecule ephrinB2 in spinal cord astrocytes contributes to motor neuron damage and loss of diaphragm function.

    Cerebellar nuclei excitatory neurons regulate developmental scaling of presynaptic Purkinje cell number and organ growth

    Ryan T Willett, N Sumru Bayin ... Alexandra L Joyner
    The first born excitatory cerebellar nuclei neurons influence the survival of their Purkinje cell partners which stimulate the expansion of granule cells and interneurons to produce functional local circuits.

    Characterization of a Toxoplasma effector uncovers an alternative GSK3/β-catenin-regulatory pathway of inflammation

    Huan He, Marie-Pierre Brenier-Pinchart ... Alexandre Bougdour
    A genetic screen in combination with biochemical approaches reveal hijacking of the host β-catenin destruction complex by the parasite T. gondii to reprogram immune gene expression.
