Objective:  To develop and validate a targeted ipRGC immunotoxin to ultimately examine the role of ipRGCs in macaque monkeys.
Summary:  Findings demonstrated that Melanopsin-SAP was specific for ipRGCs, and induced a graded reduction in the PLR (pupillary light reflex), as well as in ipRGC-driven pupil response with concentration.
Dose:  Solutions of 0.316, 1, 3.16, 10, and 50 μg delivered intravitreally.

Objective:  Examine effects of loss of melanopsin in drakes.
Summary:  Loss of melanopsin in PMM elicits decrease in GnRH mRNA expression, gonadal regression, and sex behaviors in drakes.
Dose:  To specifically lesion melanopsin-receptive neurons, 3 μl of an anti-melanopsin-saporin conjugate (MSAP, 100 ng/ul) was injected into the lateral ventricle (n = 10). Control drakes were injected with 3 μl of equimolar unconjugated anti-melanopsin and saporin (SAP, n = 10).
