Retinoic acid receptors and retinoid X receptors in the mature retina: Subtype determination and cellular distribution

Abstract

The retinal expression pattern of RARs and RXRs is heterogeneous. The observation that RXRalpha is present in rods whereas RARalpha is present in cones, suggests a mechanism by which RA that is produced upon bleaching, could generate different responses in the two photoreceptor cell subtypes.
