    Exploitation of enhanced prime editing for blocking aberrant angiogenesis by Xionggao Huang, Wenyi Wu, Hui Qi, Xiaohe Yan, Lijun Dong, Yanhui Yang, Qing Zhang, Gaoen Ma, Guoming Zhang, Hetian Lei

    Published 2025-06-01
    “…Results: NILVs targeting VEGFR2 delivered into cultured murine vascular endothelial cells led to 51.06 % VEGFR2 T17967A in the genome analyzed by next generation sequencing and the production of DN-VEGFR2, which was found to hamper VEGF-induced VEGFR2 phosphorylation, as demonstrated by Western blot analysis. Intravitreally injection of the dual NILVs into postnatal day 12 mice in a model of oxygen-induced retinopathy, led to production of retinal DN-VEGFR2 in postnatal day 17 mice which blocked retinal VEGFR2 expression and activation as well as abnormal retinal angiogenesis without interfering with retinal structure and function, as assessed by electroretinography, optical coherence tomography, fundus fluorescein angiography and histology. …”

    Temporal evolution and factors influencing visual function and RNFL thickness in ethambutol-associated optic neuropathy by Taimin Guo, Yue Fu, Xiaoyu Xu, Xiaoning Liu, Yurong Zhang, Hui Yang

    Published 2025-04-01
    “…Macular ganglion cell-inner plexiform layer (mGCIPL) thickness showed a decreasing trend (73.20 ± 4.76 μm to 55.33 ± 4.16 μm) from 1 month post-onset. Multivariate analysis revealed that disease course was the primary factor influencing VF recovery (β = − 0.31, p = 0.001), while peripapillary retinal nerve fiber layer thinning was associated with gender, ethambutol dosage, and disease duration. …”

    Adaptation optimizes sensory encoding for future stimuli. by Jiang Mao, Constantin A Rothkopf, Alan A Stocker

    Published 2025-01-01
    “…We then asked whether this characteristic change in encoding accuracy is predicted by the temporal statistics of natural visual input. Analyzing the retinal input of freely behaving human subjects showed that the distribution of local visual orientations in the retinal input stream indeed peaks at the mean orientation of the preceding input history (i.e., the adaptor). …”
