title: Gap junctions in the eye: evidence for heteromeric, heterotypic and mixed-homotypic interactions.
abstract: Some of the best evidence that different types of gap junction proteins (connexins) interact with each other in vivo has been found in the eye. This review focuses on three diverse ocular tissues that may contain heterotypic or heteromeric gap junction channels. Each of the tissues uses gap junctions in a superlative fashion: The crystalline lens has an exceptionally high density of gap junctions; the ciliary body expresses a surprising variety of connexins; the neural retina shows remarkable specificity in the patterns of intercellular coupling.
