    Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment

    Kate A Rawlinson et al.
    A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.

    Co-expression of xenopsin and rhabdomeric opsin in photoreceptors bearing microvilli and cilia

    Oliver Vöcking et al.
    The recently characterized opsin group of xenopsins is likely a major player in animal eye evolution and may have been present in an ancient, highly plastic eye photoreceptor cell type.

    The visual pigment xenopsin is widespread in protostome eyes and impacts the view on eye evolution

    Clemens Christoph Döring et al.
    The employment of xenopsin in ciliary and mixed microvillar/ciliary eye sensory cells in several protostome animals suggests high evolutionary plasticity of photoreceptors.

    Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight

    NCD Risk Factor Collaboration (NCD-RisC)
    Changes in the prevalence of underweight, total obesity, and severe obesity are largely driven by shifts in the distribution of body mass index.

    AAV-Txnip prolongs cone survival and vision in mouse models of retinitis pigmentosa

    Yunlu Xue et al.
    AAV-Txnip prolongs vision in mouse models of blindness, enhancing lactate catabolism, mitochondrial health, and ATP production in a condition that likely has a limited glucose supply.

    Phosphorylation-mediated PTEN conformational closure and deactivation revealed with protein semisynthesis

    David Bolduc et al.
    C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.

    Ciliary and rhabdomeric photoreceptor-cell circuits form a spectral depth gauge in marine zooplankton

    Csaba Verasztó et al.
    In a zooplankton larva, ciliary and rhabdomeric photoreceptor cells work antagonistically to form a spectral depth gauge.

    A gonad-expressed opsin mediates light-induced spawning in the jellyfish Clytia

    Gonzalo Quiroga Artigas et al.
    Gamete release in the jellyfish Clytia is mediated by an opsin photopigment expressed in neurosecretory cells of the gonad ectoderm, which release an oocyte maturation hormone in response to light.
