Immunocytochemical localization of nitric oxide synthase in the mammalian retina.
The localization of nitric oxide synthase (NOS) was investigated by immunocytochemistry and immunoblotting using an antiserum against neuronal NOS in the rat, mouse, guinea pig, rabbit and cat retinae. Western blot analysis of retinal tissue extracts showed that the NOS-immunoreactive band of 155 kDa was present in all species. In the rat, mouse, guinea pig and rabbit retinae, two types of amacrine cells and a class of displaced amacrine cells were consistently NOS-labeled. In the cat retina, unlike other mammals, one type of amacrine cells and two types of displaced amacrine cells showed NOS immunoreactivity. NOS immunoreactivity was further found in some bipolar cells of the rat and guinea pig, some interplexiform cells of the mouse, some photoreceptor cells of the rabbit and some Müller cells of the cat.
