    OTX2 represses sister cell fate choices in the developing retina to promote photoreceptor specification

    Miruna Georgiana Ghinia Tegla, Diego F Buenaventura ... Mark M Emerson
    A retinal gene regulatory network prevents the formation of alternative cell fates from non-stochastic retinal progenitor cells.

    Deregulated FGF and homeotic gene expression underlies cerebellar vermis hypoplasia in CHARGE syndrome

    Tian Yu, Linda C Meiners ... M Albert Basson
    Mutations in CHD7, which cause CHARGE syndrome, cause a reduction in FGF8 signalling and subsequent abnormalities in the cerebellar vermis in both mice and humans.

    The human amniotic epithelium confers a bias to differentiate toward the neuroectoderm lineage in human embryonic stem cells

    Daniela Ávila-González, Wendy Portillo ... Néstor F Díaz
    Interaction of human embryonic stem cells (hESC) with human amniotic epithelial cells (hAEC) confers hESC a pluripotent potential that resembles the anteriorized epiblast, which is predisposed to form the neural ectoderm.

    Stretching of the retinal pigment epithelium contributes to zebrafish optic cup morphogenesis

    Tania Moreno-Mármol, Mario Ledesma-Terrón ... Paola Bovolenta
    Retinal pigment epithelium flattening is an efficient solution adopted by the fast-developing zebrafish to enable folding of the eye primordia, which contrasts with the proliferation-based mechanism used by amniotes.

    Mutation of vsx genes in zebrafish highlights the robustness of the retinal specification network

    Joaquín Letelier, Lorena Buono ... Juan R Martínez-Morales
    Depletion of vsx genes in zebrafish confirms a conserved role in bipolar cells specification across vertebrates, but do not interfere with the formation of the neural retina domain, which reveal an unexpected robustness of the genetic network sustaining the retina.

    A transcriptome atlas of the mouse iris at single-cell resolution defines cell types and the genomic response to pupil dilation

    Jie Wang, Amir Rattner, Jeremy Nathans
    Using single nucleus RNA sequencing, a complete catalogue of cell types was determined for the mouse iris, and this information was used as a starting point to define the effects of pupil dilation on gene expression and on nuclear morphology.

    Computational design of peptides to target NaV1.7 channel with high potency and selectivity for the treatment of pain

    Phuong T Nguyen, Hai M Nguyen ... Vladimir Yarov-Yarovoy
    Rationally designed peptide inhibitors of human voltage-gated channels have transformative potential to define a new class of biologics to treat pain.

    Epigenomic landscapes of retinal rods and cones

    Alisa Mo, Chongyuan Luo ... Jeremy Nathans
    Genome-wide analysis of DNA methylation and accessible chromatin shows that retinal rods and cones have distinct epigenomic features that reflect differences in their development and function.

    Transcriptomic atlas of midbrain dopamine neurons uncovers differential vulnerability in a Parkinsonism lesion model

    Behzad Yaghmaeian Salmani, Laura Lahti ... Thomas Perlmann
    Single nuclei RNA sequencing unmasks 16 variants of midbrain dopamine neurons within a continuum of their gene expression landscape and resolves their differential vulnerability.
