T helper (Th)-17 is a recently identified subtype of Th response that has been implicated in host defense and autoimmunity. We investigated whether there is evidence for a Th-17 response in human and experimental murine dry eye (DE). Gene expression in the human DE conjunctiva showed increased levels of the Th-17 inducers, interleukin (IL)-23, IL-17A, and(More)
Although the effects of the interleukin 13 (IL-13) on goblet cell (GC) hyperplasia have been studied in the gut and respiratory tracts, its effect on regulating conjunctival GC has not been explored. The purpose of this study was to determine the major IL-13-producing cell type and the role of IL-13 in GC homeostasis in normal murine conjunctiva. Using(More)
BACKGROUND The conjunctiva contains a specialized population of lymphocytes that reside in the epithelium, named intraepithelial lymphocytes (IEL). METHODOLOGY/PRINCIPAL FINDINGS Here we characterized the IEL population prior to and after experimental desiccating stress (DS) for 5 or 10 days (DS5, DS10) and evaluated the effect of NK depletion on DS. The(More)
BACKGROUND IL-2 has classically been considered a cytokine that regulates T cell proliferation and differentiation, signaling through its heterotrimeric receptor (IL-2R) consisting of alpha (CD25), beta (CD122), gamma chains (CD132). Expression of IL-2R has also been detected in mucosal epithelial cells. Soluble IL-2Ralpha (CD25) has been reported as an(More)
OBJECTIVES IL-2ralpha (CD25)(-/-) mice develop autoimmunity and lymphoproliferative disorders, including SS-like disease. The objective of this study was to evaluate the severity of corneal epithelial disease and T-cell cytokine profile in the ocular surface tissues of CD25KO mice. METHODS CD25KO mice were evaluated at 8, 12 and 16 weeks of age. Corneal(More)
To investigate time-related immunopathological changes in the lacrimal glands (LGs) of CD25KO mice, we examined LGs of C57BL/6 (wild-type) and CD25KO mice at 8, 12, and 16 weeks of age. T cell infiltration was quantified by flow cytometry, and gland function by tear peroxidase activity and epidermal growth factor mRNA expression. T helper (Th)-1, -2 and(More)
PURPOSE To investigate the effects of cholinergic blockade on inflammatory cell infiltration and cytokine production in the mouse lacrimal gland (LG). METHODS C57BL/6 mice were untreated (UT) or received subcutaneous injections of either scopolamine hydrobromide (SCOP; 0.5 mg/0.2 mL) or saline (SAL) four times daily for 2 or 5 days (2D, 5D). This was(More)
OBJECTIVE To investigate the protective effects of c-Jun N-terminal kinase (JNK)-1 and -2 gene knockout (KO) on the corneal epithelial response to desiccating stress. METHODS The C57BL/6, JNK1KO, and JNK2KO mice were subjected to desiccating stress (DS) for 5 days. The effects of DS on the corneal epithelium were evaluated by measuring corneal smoothness(More)
