PURPOSE To determine whether CD4(+)CD25(+) T-regulatory cells (Tregs) from the eyes of rats with recurrent (r) experimental autoimmune uveitis (EAU) were less efficient in suppressing intraocular inflammation than those from rats with monophasic (m) disease (m-EAU). METHODS m-EAU and r-EAU were induced in Lewis rats by immunization with R16 or by adoptive transfer of R16-specific T cells, res...

PURPOSE In experimental autoimmune uveitis (EAU), recent work has demonstrated that retinal damage involves oxidative stress early in uveitis, before macrophage cellular infiltration. The purpose of this study was to determine whether oxidative mitochondrial DNA damage occurs early in EAU, before leukocyte infiltration. METHODS Lewis rats were immunized with S-antigen mixed with complete Freu...

BACKGROUND Self-harm has considerable societal and economic costs and has been extensively studied in relation to alcohol involvement. Although early onset alcohol use (EAU) has been causally linked to maladaptive clinical outcomes, its association with self-harm is less well characterized. This study aimed to further examine the link between EAU and both nonsuicidal self-injury (NSSI) and suic...

To evaluate the potential role of NK1.1 (CD161c) cells in autoimmune uveoretinitis, we treated experimental autoimmune uveoretinitis (EAU)-susceptible mice with anti-CD161c antibodies (PK136) to deplete natural killer (NK) cells. Injection of anti-CD161c antibodies deleted NK cells from the peripheral blood of EAU-susceptible mice. The T cell proliferative response against the ocular autoantige...

Experimental autoimmune uveoretinitis (EAU) is an organ-specific T cell-mediated disease induced by immunizing mice with interphotoreceptor retinoid binding protein (IRBP). Autoaggressive CD4(+) T cells are the major pathogenic population for EAU. We investigated the contribution of Notch signaling in T cells to EAU pathogenesis because Notch signaling regulates various aspects of CD4(+) T cell...

RATIONALE Excess alcohol use (EAU) is associated with adverse TB treatment outcomes. OBJECTIVE We investigated the relationship between EAU and death among TB patients 15 years and older prescribed anti-TB treatment in the United States. DESIGN Using data reported to the National Tuberculosis Surveillance System for 1997-2012, we calculated adjusted odds ratios and excess attributable risk ...

The model of experimental autoimmune uveitis (EAU) in mice and in rats is described. EAU targets immunologically privileged retinal antigens and serves as a model of autoimmune uveitis in humans as well as a model for autoimmunity in a more general sense. EAU is a well-characterized, robust, and reproducible model that is easily followed and quantitated. It is inducible with synthetic peptides ...

Experimental autoimmune uveitis (EAU) has been associated with a Th1 response. However, in IFN-gamma-deficient mice, EAU develops in the context of an effector response having Th2-like elements, and administration of IL-12 to mice immunized for EAU induction can be protective. We, therefore, investigated whether endogenous IL-12 is required for development of EAU. IL-12 p40-deficient mice (12KO...

PURPOSE IRBPp-specific regulatory immunity is found in the spleens of mice recovered from experimental autoimmune uveoretinitis (EAU). Induction of this regulatory immunity is dependent on the expression of the melanocortin 5 receptor (MC5r). Therefore, the authors investigated whether dependence on the expression of MC5r was with the T cells or with the APCs mediating protective regulatory imm...

PURPOSE. Both Th17 and Th1 cells contribute to experimental autoimmune uveoretinitis (EAU). Interleukin-6 (IL-6) blockade inhibits Th17 differentiation in EAU and potently suppresses ocular inflammation, although its effect on Th1 cells is unknown. To clarify the mechanism of IL-6 blockade, the authors investigated T helper cells with particular focus on Th1 and regulatory T cells (Treg) in EAU...
