Host retinal circuitry

Host retinal circuitry refers to the organized network of neuronal cell types and synaptic connections in the host retina, including photoreceptors (rods and cones), interneurons (horizontal, bipolar, amacrine cells), and retinal ganglion cells. These cells are arranged in distinct nuclear and plexiform layers, mediating visual signal processing through excitatory and inhibitory pathways. The host retinal circuitry is central to vision and is studied both for its fundamental neuroscience value and as a substrate for regenerative and transplantation therapies in retinal degenerative disorders. It is not a single molecular target, but an anatomical and functional system encompassing diverse molecules and cell types.
