HLA/Bf haplotypes were examined in a large three-generation Newfoundland family with a high incidence of Graves' disease. In that family Graves' disease was inherited in association with the haplotype HLA Aw24, Bw39 in some instances and with HLA B8-containing haplotypes in other instances. As all seven members of the family who suffered from Graves' disease were homozygous for the Bf S allele, the study for Bf was uninformative. However, the examination of other HLA/Bf haplotypes disclosed some interesting associations. One-hundred-and-five out of 168 HLA-A, -B, -Bf haplotypes were Bf S. Although numerically deviant, no unusual HLA B/Bf associations were observed. Bf F entered the family only once. A new finding is the association between HLA B27 and Bf S1; the haplotype entered the family once and was passed on to eight family members over three generations. Bf S1 was previously reported in association with HLA B12 or W21. None of these family members had ankylosing spondylitis. The Bf allele F1 entered the family three times, always in association with HLA B18.

Ocular inflammatory diseases and ocular adnexal lymphoid tumors have become less obscure and intimidating by virtue of our ability to study the infiltrates in these various diseases for their B-lymphocyte and T-lymphocyte composition. Comparisons are also possible between lymphocytic profiles in the peripheral blood and the precise composition of the in situ infiltrates within the ocular tissue themselves. The availability of monoclonal antibodies, which can determine T-lymphocytic subsets such as T-helper cells and T-suppressor/cytotoxic cells, natural killer cells, and monocytes-histiocytes, has provided a powerful technology for the delineation of the distinctive immune composition of the inflammatory infiltrates, as well as any possible disturbances in T-cell immunoregulation. B-lymphocytes produce immunoglobulins, which may be misdirected as autoantibodies in local or systemic autoimmune diseases. Immunoglobulin-mediated and therefore B-cell derived conditions include vasculitis, progressive cicatricial ocular pemphigoid, Mooren's corneal ulcer, scleritis, and hay fever and vernal conjunctivitis. Other diseases in which B-lymphocytes, their immunoglobulin products or immune complexes formed with presently unknown antigens are potentially at fault are chronic non-specific uveitis; iridocyclitis in Behcet's syndrome; Fuch's heterochromic syndrome, ankylosing spondylitis, and Reiter's syndrome; Graves' disease; and idiopathic inflammatory orbital pseudotumor and myositis. T-cells do not produce immunoglobins, but rather secrete lymphokines or interact directly with receptors or determinants on viruses or target tissues (eg. immunosurveillance against neoplasia); it is possible that some autoimmune diseases are the result of neo-antigens on the surfaces of host tissues that have been coded for by a cryptic inciting virus. T-cell diseases include phlyctenulosis graft rejections, graft versus host disease, and possibly sympathetic ophthalmia and temporal arteritis. Natural killer cells are involved in many of the same diseases as cytotoxic T-cells, except that the former require no period of sensitization (natural immunity), whereas cytotoxic T-cells must undergo an antigen-specific blast transformation (acquired immunity of the delayed hypersensitivity type). In many diseases in which B-cell derived auto-antibodies are at fault, there may be local tissue or systemic T-cell imbalances, with a reduction in T-suppressor cells and a relative augmentation in T-helper cells, thereby facilitating production of misdirected auto-antibodies.(ABSTRACT TRUNCATED AT 400 WORDS)

Structural and functional homology between bacterial proteins and host antigens, called molecular mimicry, is considered as significant pathogenic factor involved in several autoimmune diseases. The most important examples of this phenomenon reviewed in this work, involve rheumatic fever, Graves' disease, ankylosing spondylitis, Reiter's syndrome and rheumatic arthritis caused by infections with Streptococcus, Yersinia, Klebsiella, Escherichia coli, respectively.

Recent large-scale genome-wide association (GWA) studies of SNP variations captured many thousands individual genetic profiles of H. sapiens and facilitated identification of significant genetic traits which are highly likely to influence the pathogenesis of several major human diseases. Here we apply the integrative genomics principles to interrogate relationships between structural features and gene expression patterns of disease-linked SNPs, microRNAs and mRNAs of protein-coding genes in association to phenotypes of 15 major human disorders, namely bipolar disease (BD); rheumatoid arthritis (RA); coronary artery disease (CAD); Crohn's disease (CD); type 1 diabetes (T1D); type 2 diabetes (T2D); hypertension (HT); ankylosing spondylitis (AS); Graves' disease (autoimmune thyroid disease; AITD); multiple sclerosis (MS); breast cancer (BC); prostate cancer (PC); systemic lupus erythematosus (SLE); vitiligo-associated multiple autoimmune disease (VIT); and ulcerative colitis (UC). We selected for sequence homology profiling a set of approximately 250 SNPs which were unequivocally associated with common human disorders based on multiple independent studies of 220,124 individual samples comprising 85,077 disease cases and 129,506 controls. Our analysis reveals a systematic primary sequence homology/complementarity-driven pattern of associations between disease-linked SNPs, microRNAs and protein-coding mRNAs defined here as a human disease phenocode. We utilize this approach to draw SNP-guided microRNA maps of major human diseases and define a consensus disease phenocode for fifteen major human disorders. A consensus disease phenocode comprises 72 SNPs and 18 microRNAs with an apparent propensity to target mRNA sequences derived from a single protein-coding gene, KPNA1. Each of microRNAs in this elite set appears linked to at least three common human diseases and has potential protein-coding mRNA targets among the principal components of the nuclear import pathway. We confirmed the validity of our findings by analyzing independent sets of most significant disease-linked SNPs and demonstrating statistically significant KPNA1-gene expression phenotypes associated with human genotypes of CD, BD, T2D and RA populations. Our analysis supports the idea that variations in DNA sequences associated with multiple human diseases may affect phenotypes in trans via non-protein-coding RNA intermediaries interfering with functions of microRNAs and defines the nuclear import pathway as a potential major target in 15 common human disorders.

The HLA region encodes several molecules that play key roles in the immune system. Strong association between the HLA region and autoimmune disease (AID) has been established for over fifty years. Association of components of the HLA class II encoded HLA-DRB1-DQA1-DQB1 haplotype has been detected with several AIDs, including rheumatoid arthritis, type 1 diabetes and Graves' disease. Molecules encoded by this region play a key role in exogenous antigen presentation to CD4+ Th cells, indicating the importance of this pathway in AID initiation and progression. Although other components of the HLA class I and III regions have also been investigated for association with AID, apart from the association of HLA-B*27 with ankylosing spondylitis, it has been difficult to determine additional susceptibility loci independent of the strong linkage disequilibrium (LD) with the HLA class II genes. Recent advances in the statistical analysis of LD and the recruitment of large AID datasets have allowed investigation of the HLA class I and III regions to be re-visited. Association of the HLA class I region, independent of known HLA class II effects, has now been detected for several AIDs, including strong association of HLA-B with type 1 diabetes and HLA-C with multiple sclerosis and Graves' disease. These results provide further evidence of a possible role for bacterial or viral infection and CD8+ T cells in AID onset. The advances being made in determining the primary associations within the HLA region and AIDs will not only increase our understanding of the mechanisms behind disease pathogenesis but may also aid in the development of novel therapeutic targets in the future.

Autoimmune diseases have environmental and genetic components. These are the microbial trigger, the immunity system component and the genetic component. Here we describe these components and how they interact. Known microbial triggers are Streptococcus pyogenes for rheumatic carditis, Proteus mirabilis for rheumatoid arthritis and Klebsiella pneumoniae for ankylosing spondylitis. The immunity system component has been clarified by realisation that no autoimmune disease is caused by loss of suppressor T cells. This leaves Burnet's forbidden clones, clearly seen in Graves' disease, as the immunological defect. With wide scope for clonal diversification by somatic gene mutations, to prevent frequent autoimmunity the immunity system is policed by the histocompatibility system. This dictates the immune response repertoire by deleting complementary clones (H Gene Theory). We show molecular evidence of how specific histocompatibility antigens can predispose to an autoimmune disease by influencing choice of the microbial antigen to which the immunity system reacts. Because of the unlucky random element in the somatic mutations involved in their development, forbidden clones are unlikely to reappear in new immune repertoires developing after immune ablation and autologous bone marrow cell reconstitution, as observed clinically. Isolation of autoantigens and their attachment to cytotoxic moieties could provide specific immunotherapy for autoimmune diseases. Kaplans's discovery that xenografts can be accepted without rejection after immune ablation followed by autologous and xenogeneic bone marrow inoculation, could enable widespread use of pig grafts for humans.

The aim of our study is to assess the association of NFKB1 -94ins/delATTG promoter polymorphism with autoimmune and inflammatory diseases using a meta-analysis. We surveyed the studies on the association of NFKB1 -94ins/delATTG promoter polymorphism with autoimmune and inflammatory diseases. Meta-analysis was performed for genotypes DD vs WW, WD vs WW, DD vs WW + WD, WD + DD vs WW, and D allele vs W allele in a fixed/random effect model. Seventeen studies (7312 cases and 6193 controls) were identified. When all groups were pooled, we found no association between NFKB1 -94ins/delATTG promoter polymorphism and autoimmune and inflammatory diseases. In ethnic subgroup analyses, we found no association between NFKB1 -94ins/delATTG promoter polymorphism and autoimmune and inflammatory diseases in the Caucasian population. However, an association of NFKB1 -94ins/delATTG promoter polymorphism with autoimmune and inflammatory diseases was found in the Asian population [D vs W: odds ratio (OR) = 0.87, 95% confidence interval (CI) = 0.77-0.99, P = 0.03; WD + DD vs WW: OR = 0.79, 95% CI = 0.65-0.95, P = 0.01; DD vs WW + WD: OR = 0.92, 95% CI = 0.73-1.16, P = 0.11; DD vs WW: OR = 0.80, 95% CI = 0.62-1.03, P = 0.09; WD vs WW: OR = 0.78, 95% CI = 0.65-0.95, P = 0.01]. In disease subgroup analyses, we found no association between NFKB1 -94ins/delATTG promoter polymorphism and inflammatory bowel disease, ankylosing spondylitis and Graves' disease. This meta-analysis suggests a possible association between NFKB1 -94ins/delATTG promoter polymorphism and certain autoimmune and inflammatory diseases in the Asian population, but not in the Caucasian population. This finding demands further investigation.

Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a strong susceptibility gene shared by many autoimmune diseases. The aim of this study was to explore the mechanisms underlying this relationship. We performed a comprehensive analysis of the association between PTPN22 polymorphism C1858T and autoimmune diseases. The results showed a remarkable pattern; PTPN22 C1858T was strongly associated with type I diabetes, rheumatoid arthritis, immune thrombocytopenia, generalized vitiligo with concomitant autoimmune diseases, idiopathic inflammatory myopathies, Graves' disease, juvenile idiopathic arthritis, myasthenia gravis, systemic lupus erythematosus, anti-neutrophil cytoplasmic antibody-associated vasculitis and Addison's disease. By contrast, PTPN22 C1858T showed a negligible association with systemic sclerosis, celiac disease, multiple sclerosis, psoriasis, ankylosing spondylitis, pemphigus vulgaris, ulcerative colitis, primary sclerosing cholangitis, primary biliary cirrhosis, Crohn's disease and acute anterior uveitis. Further analysis revealed a clear distinction between the two groups of diseases with regard to their targeted tissues: most autoimmune diseases showing an insignificant association with PTPN22 C1858T manifest in skin, the gastrointestinal tract or in immune privileged sites. These results showed that the association of PTPN22 polymorphism with autoimmune diseases depends on the localization of the affected tissue, suggesting a role of targeted organ variation in the disease manifestations.

Schizophrenia is of mysterious causation. It is not infectious, not congenital, but shows familial aggregation, the Mendelian genetics indicating involvement of multiple codominant genes with incomplete penetrance. This is the pattern for autoimmune diseases, such as Graves' disease of the thyroid, where forbidden clones of B lymphocytes develop, and cause thyrotoxicosis by secreting autoantibodies that react with the thyroid gland's receptor for thyroid-stimulating hormone from the pituitary gland. In 1982, Knight postulated that autoantibodies affecting the function of neurons in the limbic region of the brain are a possible cause of schizophrenia. Today, this is even more probable, with genes predisposing to schizophrenia having being found to be immune response genes, one in the MHC and two for antibody light chain V genes. Immune response genes govern the immune repertoire, dictating the genetic risk of autoimmune diseases. The simplest test for an autoimmune basis of schizophrenia would be trial of immunosuppression with prednisone in acute cases. The urgent research need is to find the microbial trigger, as done by Ebringer for rheumatoid arthritis and for ankylosing spondylitis. This could lead to prophylaxis of schizophrenia by vaccination against the triggering microbe.

Autoimmune diseases are characterized by the impaired function and the destruction of tissues that are caused by an immune response in which aberrant antibodies are generated and attack the body's own cells and tissues. Interleukin (IL) -37, a new member of the IL-1 family, broadly reduces innate inflammation as well as acquired immune responses. Recently, studies have shown that expression of IL-37 was abnormal in autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), inflammatory bowel disease (IBD), ankylosing spondylitis (AS), psoriasis, Graves' disease (GD). In addition, functional analysis indicated that IL-37 is negatively involved in the development and pathogenesis of these autoimmune disorders. The strong association of this cytokine with autoimmune diseases promotes us to systematically review what had been published recently on the crucial nature of IL-37 in relation to autoimmune diseases gaining attention for its regulatory capability in these autoimmune disorders.
