Localization of organic anion transporting polypeptides in the rat and human ciliary body epithelium

Conclusions. Several multispecific organic anion transporting polypeptides are expressed at the basolateral plasma membrane of the non-pigmented, and to a lesser extent also of the pigmented, epithelium in rat and human ciliary body. These Oatps/OATPs can account for the previously suggested 'liver-like' transport functions of mammalian ciliary body epithelium.
