Delivery of foreign opsin genes to cone photoreceptors using recombinant adeno-associated virus (rAAV) is a potential tool for studying the basic mechanisms underlying cone based vision and for treating vision disorders. We used an in vivo retinal imaging system to monitor, over time, expression of virally-delivered genes targeted to cone photoreceptors in the Mongolian gerbil (Meriones unguiculatus). Gerbils have a well-developed photopic visual system, with 11–14% of their photoreceptors being cones. We used replication deficient serotype 5 rAAV to deliver a gene for green fluorescent protein (GFP). In an effort to direct expression of the gene specifically to either S or M cones, the transgene was under the control of either the human X-chromosome opsin gene regulatory elements, i.e., an enhancer termed the locus control region (LCR) and L promoter, or the human S-opsin promoter. Longitudinal fluorescence images reveal that gene expression is first detectable about 14 days post-injection, reaches a peak after about 3 months, and is observed more than a year post-injection if the initial viral concentration is sufficiently high. The regulatory elements are able to direct expression to a subpopulation of cones while excluding expression in rods and non-photoreceptor retinal cells. When the same viral constructs are used to deliver a human long-wavelength opsin gene to gerbil cones, stimulation of the introduced human photopigment with long-wavelength light produces robust cone responses.

Stimulation of dark-adapted rods can shift the hues associated with specific wavelengths throughout the spectrum: Rods exert a green bias (strengthen green relative to red) at longer wavelengths and a blue bias (strengthen blue relative to yellow) at short-to-middle wavelengths. A third rod influence at shorter wavelengths is more complicated because it has been shown to reverse direction with change of stimulus duration. Thus, for 30-ms stimuli, rods exert a green bias like that observed at longer wavelengths. However, for 1-s stimuli, rods exert a red bias that is observed nowhere else in the spectrum. We examined the latency (time course) of rod hue biases by measuring the shifts of the three spectral unique hues under dark-adapted versus bleached (cone plateau) conditions. The rod green bias at unique yellow (mean 10 nm) and, in contrast to some prior studies, the rod blue bias at unique green (mean 21 nm) were not systematically affected by test stimulus duration. A quick rod green bias (mean 5 nm) was shown at unique blue for two of three observers but was dominated by a slower rod red bias (mean 11 nm) after 30–50 ms of rod stimulation. These opposing rod influences may reflect competing effects of rod signals on ML-cone and S-cone pathways.
