    Regulation of retinal axon growth by secreted Vax1 homeodomain protein

    Namsuk Kim, Kwang Wook Min ... Jin Woo Kim
    Secreted Vax1 homeodomain protein supports the development of optic chiasm by directly acting at the retinal ganglion cell axon.

    CCR1 mediates Müller cell activation and photoreceptor cell death in macular and retinal degeneration

    Sarah Elbaz-Hayoun, Batya Rinsky ... Itay Chowers
    A novel therapy for a common blinding retinal disease uses an innovative CCR1 blocking-based strategy.

    Towards biologically plausible phosphene simulation for the differentiable optimization of visual cortical prostheses

    Maureen van der Grinten, Jaap de Ruyter van Steveninck ... Yağmur Güçlütürk
    The provided framework based on biological models and clinical literature can aid in the optimization of visual cortical prostheses through computational or behavioral simulation experiments, serving as a flexible tool for computational, clinical, and behavioral neuroscientists working on visual neuroprosthetics.

    The cell adhesion molecule Sdk1 shapes assembly of a retinal circuit that detects localized edges

    Pierre-Luc Rochon, Catherine Theriault ... Arjun Krishnaswamy
    A novel retinal ganglion cell requires a cell adhesion molecule to grow its dendrites, collect synaptic inputs, and become selective to edges placed in its receptive field.

    Subretinal mononuclear phagocytes induce cone segment loss via IL-1β

    Chiara M Eandi, Hugo Charles Messance ... Florian Sennlaub
    IL-1β release from macrophages might be responsible for the unexplained cone segment loss in retinal degenerative diseases that are associated with subretinal inflammation, such as retinitis pigmentosa or geographic atrophy.
    1. Neuroscience

    Distinct ipRGC subpopulations mediate light’s acute and circadian effects on body temperature and sleep

    Alan C Rupp, Michelle Ren ... Tiffany M Schmidt
    Daily fluctuations versus transient perturbations in environmental light influence behavior and physiology through distinct circuits.
    1. Neuroscience

    Optogenetic activation of visual thalamus generates artificial visual percepts

    Jing Wang, Hamid Azimi ... Gregor Rainer
    The visual thalamus is a promising target for neural prosthetic intervention aimed at the restoration of visual function.
    1. Neuroscience

    Melanopsin activates divergent phototransduction pathways in intrinsically photosensitive retinal ganglion cell subtypes

    Ely Contreras, Jacob D Bhoi ... Tiffany M Schmidt
    Melanopsin phototransduction targets distinct complements of transduction channels across intrinsically photosensitive retinal ganglion cell subtypes and does not require hyperpolarization-activated cyclic nucleotide-gated channels.

    Lhx2 is a progenitor-intrinsic modulator of Sonic Hedgehog signaling during early retinal neurogenesis

    Xiaodong Li, Patrick J Gordon ... Edward M Levine
    The LIM-homedomain transcription factor Lhx2 confers competence to retinal progenitor cells to activate and maintain Sonic Hedgeghog signaling at physiological levels during a key phase of tissue growth and cell type generation.
