Top View of Horizontal Cells in the Retina (image) Institute of Molecular and Clinical Ophthalmology Basel Share Print E-Mail Caption Retinal horizontal cells express a chemogenetic channel after systemic AAV infection. Cell bodies of horizontal cells are labeled in red; chemogenetic channels are labeled in yellow. Strong expression of the chemogenetic channel in the entire horizontal cell network allowed us to reversibly and efficiently perturb the activity of all horizontal cells throughout the retina, which had not been possible before. The image was obtained using a confocal microscope.
