Atypical gap junctions in the ciliary epithelium of the albino rabbit eye
نویسندگان
چکیده
Gap junctions are present between nonpigmented and pigmented epithelial cells layers, as well as between the adjacent pigmented cells, but not between the nonpigmented epithelial cells which face the posterior chamber. The unusual feature of these gap junctions is a dark banding which regularly appears every three rows of subunits. This dark band is the equivalent width of two rows of facets.

Intercellular junctions of the ciliary epithelium in anterior uveitis.
The intercellular junctions of the anterior ciliary and iridial epithelia of the inflamed rabbit eye were examined by use of an ultrastructural tracer, conventional electron microscopy, and the freeze-fracture technique. In normal control eyes, intravascularly injected horseradish peroxidase was prevented from entering the posterior chamber by the zonulae occludentes of the nonpigmented ciliary...
متن کاملDepression of intraocular pressure following inactivation of connexin43 in the nonpigmented epithelium of the ciliary body.
PURPOSE Conditional inactivation of connexin43 (Cx43) in the pigmented epithelium of the mouse eye results in a reduction in aqueous humor production and complete loss of the vitreous chamber. It was proposed that gap junctions between pigmented and nonpigmented epithelia of the ciliary body are critical for the production of the aqueous humor. To form such junctions, Cx43 in the pigmented epit...

The structure of gap junctions in the rabbit ciliary epithelium, corneal endothelium, and mouse stomach and liver was studied with the freeze-fracturing technique after rapid freezing to near 4 degrees K from the living state. In the ciliary epithelium, the connexons were randomly distributed, separated by smooth membrane matrix. In the corneal endothelium, both random and crystalline arrangeme...

In the present study, the lenses and ciliary bodies of 20 ostrich eyes were studied macroscopically and microscopically. The histological slides were studied after staining by hematoxylin and eosin, Verhoeff, Van Gieson, and periodic acid-Schiff (PAS). Posterior surface of lens was more convex than its anterior surface. The average lens diameter and thickness were respectively measured as 1.43 ...
متن کاملConnexin distribution in the rabbit and rat ciliary body. A case for heterotypic epithelial gap junctions.
PURPOSE To evaluate the distribution of different alpha- and beta-type connexins (Cx) present in the dual layered ciliary body epithelia (CBE) of both rabbit and rat. METHODS Immunocytochemical detection of Cx26, Cx32, Cx43, and Cx50 was performed on frozen sections of rabbit and rat ciliary body using indirect immunofluorescent methods. The identity of the antigens recognized by the monoclon...
