Experimental autoimmune dacryoadenitis. I. Lacrimal gland disease in the rat.

Experimental autoimmune dacryoadenitis was produced in Lewis rats by immunization with a single intradermal administration of a 3M KCl extract of exorbital lacrimal gland in CFA, when enhanced by simultaneous i.v. injection of killed Bordetella pertussis. No significant lacrimal lesions were observed in control animals immunized with the extracts of Harderian or salivary glands. Gel filtration of the 3M KCl extract on Sephacryl S-300 column yielded three protein fractions. Only fraction III (MW = 10-55K) induced marked dacryoadenitis following a single injection of 2.0 mg protein in CFA plus pertussis. The infiltrates in the exorbital lacrimal lesions were first apparent around the ducts and associated vasculature. From this area, the infiltrates appeared to spread to the acini drained by these ducts, ultimately involving as much as 30-50% of the gland. The affected glands most commonly showed a diffuse nongranulomatous infiltrate of small lymphocytes, macrophages, and plasma cells; this was focal in nature, involving acinar atrophy and breakdown, and replaced the normal architecture in extreme cases. The Harderian and salivary glands were uninvolved in these animals, suggesting a restricted specificity of this response. Lewis rats immunized with exorbital lacrimal gland fractions I or II in CFA plus pertussis showed only minimal lesions, similar to controls receiving CFA and pertussis without antigen. These findings suggest that an autoantigen exists in the lacrimal gland of the rat that is capable of inducing a specific lymphoproliferative dacryoadenitis.[1]
