Lacrimal Histopathology and Ocular Surface Disease in a Rabbit Model of Autoimmune Dacryoadenitis

Abstract

Injection of activated PBLs (i.e., AMCR-PBLs) in the lacrimal gland induces autoimmune dacryoadenitis with immunopathologic features similar to those of Sjögren's syndrome. The lacrimal immunopathology is accompanied by typical clinical manifestations of dry eye syndrome. The persistent significant dry eye does not appear to result just from failure of the diseased gland but from a more general dysfunction of the surface secretory tissues.
