Inhibition of very late antigen-4 and leukocyte function-associated antigen-1 in experimental autoimmune uveoretinitis

B10.RIII mice were immunized with interphotoreceptor retinoid binding protein peptide to induce uveitis. Mice were injected intraperitoneally with anti-very late antigen-4 (VLA-4), anti-leukocyte function-associated antigen-1 (LFA-1), or a control Ab every other day from Day 5 to Day 13 post-immunization. The eyes and spleens were harvested on Day 14 or 28. The eyes were used for histologic/cytokine mRNA expression analyses. The spleens were used for Ag-recall cytokine production assays and intracellular cytokine assays. Treatment with both Abs led to a profoundly significant reduction in severity of uveitis and cytokine mRNA expression in the eye. However, cytokine production by splenocytes was significantly upregulated. Discontinuation of Ab treatment led to an increase in uveitis severity and cytokine mRNA expression in the eye, but led to a decrease in cytokine production and intracellular IFN-γ⁺ and IL-17A⁺cytokine profile by splenocytes. Thus, blockade of these molecules using specific Abs may be a therapeutic option for patients with uveitis; however, such treatment must be continued.     

Roles of Toll-Like Receptor 4 for Cellular Pathogenesis in Primary Open-Angle Glaucoma: A potential therapeutic strategy

In recent years, glaucoma has been proposed as an autoimmune disease and an understanding immune-regulation concept has been applied for novel glaucoma therapy. Current evidence suggests an innate immunity is a keystone step for primary open angle glaucoma (POAG) pathogenesis resulting from trabecular meshwork (TM) cell fibrosis and retinal ganglion cell (RGC) death. Toll-like receptor 4 (TLR4) is a common player in the innate immunity, which appears on the TM and RGC of POAG. The activation of TLR4 regulates several molecules involving both fibrosis and cell death. Inhibition of TLR4 decreases TGF-β2-induced fibrosis in TM cells and enhances cell survival of RGC in both optic nerve crush and ischemia models. In this review, we will summarize the molecular mechanisms of TLR4 related to POAG pathogenesis. An understanding of this mechanism may provide novel development of therapeutic strategies for POAG.     

Transgenic overexpression of anti-double-stranded DNA autoantibody and activation of Toll-like receptor 4 in mice induce severe systemic lupus erythematosus syndromes

Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disease characteristized by the presence of autoantibodies against double-stranded DNA (anti-dsDNA) in sera at high levels. Bacterial infections in SLE are associated with higher morbidity and mortality. Our goal was to observe the interaction between these 2 factors in the pathogenesis of lupus. We generated transgenic mice with monoclonal anti-dsDNA to investigate the development of lupus. By challenging the mice in vitro and in vivo with Toll-like receptor 4 (TLR4) ligand lipopolysaccharides (LPS), we were able to examine the role of bacterial infection in SLE. In our study, the transgenic mice with a secreted form of anti-dsDNA were found to have higher levels of anti-nuclear antibodies, anti-dsDNA, blood urea nitrogen, and proteinuria. The splenocytes of the mice stimulated with LPS secreted more anti-dsDNA, IFN-γ, and IL-10. After injecting them with LPS in vivo, we further found higher immune complex depositions and IL-10 in the kidneys of the transgenic mice. Moreover, the LPS-injected transgenic mice had higher mortality rate. This is the first transgenic model to demonstrate that only 2 risk factors, pathogenic anti-dsDNA and TLR4 activation, induce severe SLE syndromes in normal mice through the overproduction of IL-10 and IFN-γ. These findings imply that anti-dsDNA and bacterial infections have pivotal roles in the pathogenesis of SLE; the inhibition of TLR4 may be regarded as a therapeutic target.

The regulation effect of ulinastatin on the expression of SSAT2 and AQP4 in myocardial tissue of rats after cardiopulmonary resuscitation

Objective: This study aims to investigate the regulation effects of ulinastatin (UT1) on the expression of spermidine/spermine -N1-acetyltransferase 2 (SSAT2) and aquaporin 4 (AQP4) in myocardial tissue of rats after cardiopulmonary resuscitation (CPR) and their correlations. Methods: A total of 90 adult SD rats were divided into sham operation group (A, n=30), model group (B, n=30) and UT1 group (C, n=30). The cardiac arrest (CA) and CPR model was established by asphyxia method. Left ventricular fractional shortening (LVFS), left ventricular ejection fraction (LVEF) and E/A peak ratio of mitral valve in three groups were collected by ultrasonic echocardiography. Apoptosis of myocardial cells was detected by DAPI staining. The expression levels of SSAT2 and AQP4 were detected by RT-PCR, Western blotting and immunohistochemical methods. Results: UT1 could significantly improve the levels of LVFS, LVEF and E/A ratio and decrease myocardial cell apoptosis. As compared with group B, the expression level of SSAT2 increased and the expression level of AQP4 decreased in group C (P<0.01). SSAT2 was the most in group A and the least in group B while AQP4 was the least in group A and the most in group B (P<0.01). There was positive correlation between SSAT2 and cardiac function in CRP model while there was negative correlation between AQP4 and cardiac function (P<0.01). The expression of SSAT2 and AQP4 protein in myocardial tissue was negatively correlated in CRP model (r=-0.920, P<0.01). Conclusions: UT1 can effectively reduce the cardiac function damage caused by CRP, which could be related with the increased SSAT2 and decreased AQP4.

Gene Polymorphism of Interleukin-4, Interleukin-4 Receptor and STAT6 in Children with Atopic Dermatitis in Taif,Saudi Arabia

Aim of study: This work was performed to evaluate the level of IL-4, and to clarify the role of IL-4 gene polymorphism at position cytosine –590-to-thyamine (C-590T), IL-4Rα gene polymorphism at position adenine +4679-to-guanine (A+4679G) [isoleucine-50-valine (I50V)] and STAT6 gene polymorphism at position guanine 2964-to-adenine (G2964A) in Saudi children with non-atopic dermatitis (non-AD) and atopic dermatitis (AD) to identify their role in the pathogenesis of these diseases.

Subjects and methods: This study included 150 children: 50 healthy children as controls, 50 with non-AD, and 50 with AD. They were subjected to full clinical examination, complete blood picture, skin prick test, and determination of serum interleukin-4 (IL-4) and total immunoglobulin-E (IgE) levels. Detection of interleukin-4 gene (C-590T), interleukin-4 receptor alpha gene (A+4679G) (I50V), and STAT6 gene (G2964A) polymorphisms were performed by PCR-based restriction fragment length polymorphism (PCR-RFLP).

Results: There was a significant (P < 0.01) association between genotype and allele frequencies of IL-4Rα (A+4679G) (I50V) polymorphism in the AD group (but not non-AD group). Moreover, there was a significant association between genotype and allele frequencies of the STAT6 (G2946A) polymorphism in the non-AD (P < 0.05) and AD (P < 0.01) groups. On the other hand, there was no significant association between genotype and allele frequencies of the (C-590T) polymorphism in the non-AD group and AD group. There was a significant (P < 0.001) higher total IgE level in patients compared to the controls. Moreover, the mean values of total IgE were significantly different among the different allelic variants of (C-590T), (I50V), (G2964A) polymorphisms of IL-4, IL-4Rα, and STAT6 genes, respectively, in all the studied groups. On the other hand, there was no significant difference of serum IL-4 levels among all the studied patients, or among the different allelic variants of (C-590T), (I50V), (G2964A) polymorphisms of IL-4, IL-4Rα, and STAT6 genes, respectively.

Conclusion: IL-4Rα gene (I50V) and STAT6 gene (G2964) polymorphisms may play a role in development of eczema; however, the IL-4 gene polymorphism (C-590T) had no relationship with susceptibility to the disease among Saudi children.
