Retinal degenerative diseases pose significant therapeutic challenges; however, optogenetic vision restoration offers a promising strategy that is independent of mutations and disease progression. Optogenetic tools consisting of photosensitive membrane proteins can be ectopically expressed in retinal cells, effectively converting them into artificial photoreceptors. This review outlines the development and application of optogenetic tools to restore light sensitivity in degenerated retinas.

Objectives: The aim of this study was to assess the efficacy and safety of TricValve system at 1-year follow-up.
Methods: TricBicaval registry is a multicenter registry that retrospectively enrolled all consecutive patients with severe TR treated with TricValve system.
Brain organization emerges from molecular, cellular, and systems-level processes that together generate cognitive function. While individual biological codes have been characterized at specific scales, their integration across levels remains poorly understood. Existing theories of consciousness recognize diverse electrophysiological signatures but fail to explain the continuity linking molecular and neural codes.

Recent advances in functionalized lipid probes - equipped with photoactivatable crosslinkers, affinity handles, and photocleavable protecting groups - have enabled proteomics-based identification of lipid interacting proteins with unprecedented specificity and resolution. Despite the growing number of published lipid interactomes, there remains no centralized effort to harmonize, compare, or integrate these datasets.

The AD-associated risk variant reduces splicing of the sialic acid-binding domain and increases expression of the full-length (sialic acid-binding) CD33 isoform seven-fold compared to the protective genotype. Here we identify CD45 as an immune cell-specific sialic acid-dependent CD33 binding partner, whose phosphatase activity is inhibited by CD33.
