INFLAMMATION-INDUCED CHANGES IN ADENOSINE 3',5'-CYCLIC-MONOPHOSPHATE PRODUCTION BY CILIARY EPITHELIAL-CELL BILAYERS

EXPERIMENTAL EYE RESEARCH, 60(2), 165–171.

By: L. Fleisher n, J. Ferrell n & M. Mcgahan  n

author keywords: ADENOSINE 3',5'-CYCLIC MONOPHOSPHATE; INTERLEUKIN-1; TUMOR NECROSIS FACTOR; ANTERIOR UVEA; CILIARY EPITHELIUM; ENDOTOXIN; UVEITIS
MeSH headings : Animals; Ciliary Body / drug effects; Ciliary Body / metabolism; Colforsin / pharmacology; Culture Techniques; Cyclic AMP / biosynthesis; Epithelium / drug effects; Epithelium / metabolism; Interleukin-1 / pharmacology; Isoproterenol / pharmacology; Lipopolysaccharides / pharmacology; Male; Rabbits; Recombinant Proteins / pharmacology; Tumor Necrosis Factor-alpha / pharmacology; Uveitis, Anterior / etiology; Uveitis, Anterior / metabolism
TL;DR: The inability of IL-1 beta, TNF alpha, or the low concentration of endotoxin to increase cAMP production by bilayers, in vitro, suggests that the enhanced cAMPProduction observed with inflamed bilayer, ex vivo, was not due to a direct action of these inflammatory agonists on the ciliary epithelial bilayer.

By: L. Fleisher n, J. Ferrell n & M. Mcgahan  n

TL;DR: Intravitreal injection of human recombinant tumor necrosis factor-alpha induced inflammation in the rabbit eye characterized by dilation of blood vessels in the iris, disruption of the blood-ocular barriers, infiltration of inflammatory cells into the anterior chamber, and accumulation of prostaglandin E in intraocular fluids differed from that reported for intravitreally injected endotoxin in terms of time course and the types ofinflammatory cells in the aqueous humor.
