    ABSTRACT: A significant number of individuals are affected by autoimmune diseases, which are caused by aberrant recognition of self by the immune system. A wide variety of cells and organ systems are targets of pathologic activation of the immune mediators. Effective and safe therapies aimed at managing the chronic inflammatory aspect of many autoimmune diseases remain elusive. This review will focus on the available interventions and discuss the future of the field to prevent organ destruction by the autoimmune process.

    ABSTRACT: Short-chain fatty acids (SCFAs) including acetate, propionate and butyrate play an important role in the physiological functions of epithelial cells and colonocytes, such as immune response regulation. Human intestinal epithelial cells (IECs) contribute in intestinal immune response via different ways, such as production of different immune factors including Interleukin (IL) IL-8, which act as chemoattractant for neutrophils, and subsequently enhance inflammation. Therefore, we aimed to evaluate the effects of SCFAs on IECs viability and production of IL-8 in vitro. SCFAs were co-cultured with either normal intestinal epithelial (T4056) or adenocarcinoma derived (HT-29) cell lines for 24-96 h in the presence of E.coli lipopolysaccharides (LPS). Cell viability, proliferation, production of IL-8 and expression of IL-8 mRNA were determined in the cell cultures. The result showed that 20 mM of SCFAs was non-cytotoxic to T4056 and enhanced their growth, whereas the growth of HT-29 was inhibited. The SCFAs down regulated LPS-stimulated IL-8 secretion with different response patterns, but no obvious effects on the release of IL-8 from non LPS- stimulated cells. In conclusion, SCFAs showed regulatory effect on release of LPS-stimulated IL-8 as well as the expression of mRNA of IL-8; these might explain the anti-inflammatory and anti-carcinogenic mechanism of SCFAs.

    ABSTRACT: The present study was aimed to investigate the anti-arthritic effect of triphala and its underlying mechanism on adjuvant-induced rat model. For comparison purpose, non-steroidal anti-inflammatory drug indomethacin was used. Arthritis was induced by intradermal injection of complete Freund’s adjuvant (0.1 ml) into the right hind paw of the Wistar albino rats. Triphala (100 mg/kg body weight [bwt]) was administered intraperitoneally (from 11th to 20th day) after the arthritis induction. Arthritis induction increased the levels of reactive oxygen species (LPO and NO), elastase, and mRNA expression of pro-inflammatory cytokines (TNF-α, IL-β, IL-17, IL-6 and MCP-1), inflammatory marker enzymes (iNOS and COX-2), receptor activator of nuclear factor kappa-B ligand (RANKL), and transcription factors (NF-kB p65 and AP-1) in the paw tissues of rats. The levels of bone collagen were found to decrease with increased urinary constituents (hydroxyproline and total glycosaminoglycans) in arthritic rats. In addition, the immunohistochemistry analysis revealed increased expression of NF-kBp65 and COX-2 in the paw tissues of arthritic rats. However, administration of triphala significantly inhibited the biochemical and molecular alterations in adjuvant-induced arthritic rats compared to indomethacin (3 mg/kg bwt) as evidenced by the radiological and histopathological analysis. In conclusion, our results suggest that triphala administration ameliorate bone and cartilage degradation during rheumatoid arthritis.

    ABSTRACT: Objectives: CTLA-4 exon-1 +49A > G (rs231775) polymorphism has been reported to influence the risk for primary biliary cirrhosis (PBC) as well as type I autoimmune hepatitis (AIH-1) in many studies; however, the results still remain controversial and ambiguous. This study aimed to determine more precise estimations for the relationship between CTLA-4 +49 A > G polymorphism and the risk for PBC and AIH-1 by using a meta-analysis. Design and methods: PubMed, EMBASE and MEDLINE were searched. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the strength of the association. Results: Fifteen studies including 3661 patients with PBC and 4427 controls as well as seven studies including 1270 patients with AIH-1 and 1614 controls were identified. Our pooled analysis revealed that G allele of CTLA-4 gene +49A/G polymorphism may confer an increased risk of PBC in overall (p = 0.001, OR = 1.29; 95% CI = 1.13-1.47) and Caucasians (p = 0.001, OR = 1.32; 95% CI = 1.21-1.44). At genotypic level, the codominant, dominant and recessive models showed no significant association with PBC. With respect to AIH-1, the AG genotype demonstrated a trend for association with increased risk of AIH-1 (p = 0.04, AG vs. AA, OR = 1.20; 95% CI = 1.01-1.43). However, the CTLA-4 alleles as well as genotypes in dominant and recessive models were not associated with a risk for AIH-1 in both Caucasians and Asians. Conclusions: This meta-analysis concluded that the CTLA-4 G allele and the AG genotype were associated with an increased risk for PBC and AIH-1, respectively, suggesting the CTLA-4 +49 A/G polymorphism as a candidate of susceptibility locus to PBC and AIH-1.

    ABSTRACT: Background: The strategy of specifically depleting antigen-specific T cells can potentially be used for the treatment of allograft rejection and autoimmunity because it does not suppress the overall immune systems. Methods: In this study, we generated killer polylactic-co-glycolic acid (PLGA) microspheres by covalently coupling major histocompatibility complex (MHC) class I antigens and apoptosis-inducing anti-Fas monoclonal antibody (mAb) onto PLGA microspheres. A modified double-emulsion method was used for the preparation of cell-sized PLGA microspheres. H-2K(b)/peptide monomers were generated in-house and analyzed through flow cytometry. The killer PLGA microspheres were administered intravenously into BALB/c mice (H-2K(d)) that had previously been grafted with skin squares from C57BL/6 mice (H-2K(b)). Tumor cell challenge and third-party mixed lymphocyte culture were used to assess the general immune functions of host. Results: The alloskin graft survival was prolonged by 4 days. The killer PLGA microspheres could specifically deplete the H-2K(b) alloantigen-reactive CD8(+) T cells that infiltrated into the alloskin graft but not CD4(+) T cells, without impairment of host overall immune function. Conclusions: Here, we initially report that PLGA microspheres, which have been widely used as medicine-delivering carriers, were used to prepare antigen-specific killer complexes and treat allograft rejection. Our data highlight the therapeutic potential of this biocompatible and biodegradable antigen-specific killer effector for the treatment of allograft rejection and autoimmune disease.

    ABSTRACT: Objective: The aim of this study was to explore whether polymorphisms of intercellular adhesion molecule-1 (ICAM-1) are associated with susceptibility to Crohn's disease (CD) and ulcerative colitis (UC). Methods: The authors conducted a meta-analysis on the associations between the polymorphisms K469E and G241R of ICAM-1 and susceptibility to CD and UC. Results: A total of 8 studies with 801 patients with CD, 672 patients with UC, and 1,828 controls were included in the meta-analysis. The meta-analysis revealed no association between CD and the ICAM-1 469E allele among the subjects (OR = 1.175, 95% CI = 0.901-1.533, p = 0.233). However, stratification by ethnicity indicated an association between the ICAM-1 469E allele and CD in Europeans (OR = 1.425, 95% CI = 1.013-2.002, p = 0.042). Meta-analysis using the homozygosity also showed an association with CD in Europeans (OR = 2.054, 95% CI = 1.036-4.073, p = 0.039). The meta-analysis revealed no association between UC and the ICAM-1 K469E polymorphism. No association between CD or UC and the ICAM-1 G241R polymorphism was observed. Conclusions: This meta-analysis demonstrates that the ICAM-1 K469E polymorphism may be associated with susceptibility to CD in Europeans, but no association was found between ICAM-1 K469E and UC. In contrast, the G241R polymorphism was not found to be associated with susceptibility to either CD or UC.

    ABSTRACT: Background: Multiple sclerosis (MS) is a progressive inflammatory and neurodegenerative disease of the central nervous system (CNS), the etiology of which is still uncertain. Several case-control studies investigated the association between CD24-P226-C/T polymorphism and MS risk, and these studies have shown inconsistent results. Objective: To address the association of CD24-P226-C/T polymorphism with MS risk by meta-analysis. Methods: A comprehensive search was conducted to identify all eligible studies of CD24-P226-C/T polymorphism and MS risk up to July 2013. The odds ratios (ORs) of CD24 allele distributions in MS were analyzed against controls. Results: In total, seven case-control studies with 949 cases of MS and 1177 controls were included in this meta-analysis. The overall results showed a significant association between CD24-P226-C/T polymorphism and MS susceptibility under homozygote comparison model (OR = 2.496, 95% CI = 1.813–3.435, p < 0.0005), dominant model (OR = 1.367, 95% CI = 1.147–1.629, p < 0.0005), recessive model (OR = 2.305, 95% CI = 1.700–3.126, p < 0.0005) and allelic model (OR = 1.422, 95% CI = 1.244–1.625, p < 0.0005). However, no significant association was observed under heterozygous comparison model (OR = 1.182, 95% CI = 0.982–1.423, p = 0.078). Conclusions: This meta-analysis indicates that CD24 P266-C/T polymorphism is more associated with the risk of MS than healthy controls. However, due to the small sample size in most of the included studies, additional large-scale and well-designed case-control studies were required for the validation of this association.

    ABSTRACT: Compared to non-sensitized renal transplant recipients, patients with preformed alloantibodies are at greater risk of cellular and humoral rejection and premature graft failure. We explored the effects of adding B-cell depleting agent (rituximab) to standard rabbit anti-thymocyte globulin (rATG) induction regimen for patients with panel reactive antibody levels >50%. Following induction therapy, 14 recipients were given two doses of rituximab (375 mg/m2) within the first month post-transplantation. Their long-term outcomes were compared to a historical control group of 23 recipients who received rATG alone. Graft survival at 5 years was superior with combination therapy compared to induction therapy alone (92.9 versus 48.3%, respectively, p = 0.02). While 30% of the rATG alone group experienced cellular rejection and 26% humoral rejection, none of rituximab plus rATG renal transplant recipients group had rejection. Thus, addition of rituximab to rATG provided superior outcomes to rATG alone. This combination induction therapy should be considered for a high-risk population.

    ABSTRACT: Exacerbation and relapse of inflammatory bowel disease (IBD) is associated with reduced antibacterial immunity and increased immune regulatory activity, but the source of increased immune regulation during episodes of disease activity is unclear. Myeloid-derived suppressor cells (MDSCs) are a cell type with a well-recognized role in limiting immune reactions. MDSC function in IBD and its relation to disease activity, however, remains unexplored. Here we show that patients with either ulcerative colitis (UC) or Crohn's disease (CD) have high peripheral blood levels of mononuclear MDSCs. Especially exacerbation of disease is associated with higher levels of mononuclear MDSC counts compared with those in remission of disease. Interestingly, chronic experimental colitis in mice coincides with increased MDCS mobilization. Thus, our results suggest that mononuclear MDCS are endogenous antagonists of immune system functionality in mucosal inflammation and the depression of antibacterial immunity associated with exacerbation of disease might involve increased activity of the MDSC compartment.

    ABSTRACT: This study was conducted to evaluate the adjuvant potential of sulfated Radix Cyathulae officinalis Kuan polysaccharides (sRCPS) and their effects on specific cellular and humoral immune responses to hepatitis B subunit vaccine in mice. Our data demonstrated that sRCPS significantly promoted the rHBsAg-specific IgG, IgG1, IgG2a, and IgG2b antibody titers, the activities of natural killer cells (NK) and cytotoxic T lymphocytes (CTL), T cells proliferation, and phagocytic capacity of peritoneal macrophages. Furthermore, sRCPS increased the levels of IL-4, IL-2, and IFN-γ in CD4(+)T cells and the level of IFN-γ in CD8(+)T cells. In addition, sRCPS enhanced the expression of CD40(+), CD80(+), CD86(+), MHC I and MHC II in dendritic cells (DCs) and upregulated the mRNA levels of MHC I, MHC II. sRCPS downregulated the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells. sRCPS increased both cellular and humoral immune responses by upregulating DC maturation, and suppressing the frequency of Treg cells.

    ABSTRACT: Objective: The aim of this study was to determine whether caspase recruitment domain-containing protein 8 (CARD8) rs2043211 polymorphism was associated with susceptibility to inflammatory bowel disease (IBD). Methods: Relevant studies were searched using PubMed and Embase up to February 2014. A meta-analysis was conducted on the association between rs2043211 polymorphism and IBD using: (1) allele contrast, (2) the dominant model, (3) the recessive model, and (4) homozygote contrast. The pooled estimated of risk was obtained by random-effects model or fixed-effects model. Publication bias was assessed by Egger's test. Results: Eight relevant articles with a total of 10 534 IBD patients [6785 Crohn's disease (CD), 3713 ulcerative colitis (UC) and 36 indeterminate colitis (IC)] and 6755 healthy controls were included in the meta-analysis, which consisted of 12 studies, 12 for CD, 10 for UC, 2 for IC. There was no significant association between rs2043211 polymorphism and IBD, CD, and IC in overall population. However, stratified meta-analysis by ethnicity showed significant association between rs2043211 polymorphism and CD in the European population under the dominant model [odds ratio (OR) = 1.210, 95% confidence interval (CI) = 1.013-1.445, p = 0.036] and homozygote contrast (OR = 1.212, 95% CI = 1.005-1.461, p = 0.044). Conclusions: Our meta-analysis results indicated significant association between rs2043211 polymorphism and the susceptibility to CD under the dominant model and homozygote contrast in the European population.

    ABSTRACT: Given the importance of understanding the genetic variations involved in the pathogenesis of non-Hodgkin's lymphoma (NHL), this pilot study was designed to investigate the impact of CD38 (184C/G; rs6449182) and IL-6 (-174 G/C; rs1800795) gene polymorphism on susceptibility of Egyptians to diffuse large B cell lymphoma (DLBCL); major types of NHL. To the best of our knowledge, this study is the first one that examines CD38 polymorphism in the NHL. Genotyping polymorphism is performed using restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) for CD38 and Mutagenically separated PCR (MS-PCR) for IL-6 in 100 Egyptian NHL patients with DLBCL subtype and 119 normal controls. The serum level of IL-6 was measured using Enzyme-linked immunosorbent assay (ELISA). CD38 (184C/G) genotype is significantly increased in NHL patients (p < 0.01), while the GG genotype is significantly increased in controls (p < 0.05). Only two genotypes were found (GG and GC) in IL-6 (-174), no CC in our NHL patients and only one case in the controls. Insignificant change in IL-6 (-174 G/C) genotypes was recorded. Significantly increased serum IL-6 (p < 0.05) was positively correlated (r = 0.17; p < 0.05) with the disease. Taken together, our data stressed the importance of CD38 gene polymorphism in developing DLBCL. Our pilot study indicates that CD38 (184) CG genotype might play a role in DLBCL susceptibility in Egyptians. Additional prospective studies on larger population are needed to confirm our findings.
