The frequency of Dw2 was remarkably low, especially in females, which is of interest, as the same antigen has a low frequency in some other autoimmune diseases.
All of these seven patients had a HLA-B8-bearing haplotype, suggesting that the B8-bearing haplotype confers an extremely high "relative risk" for adrenal autoimmunity in IDDM.
HLA-A, -B, -C, and -DR antigens were determined in order to study the association of HLA in Japanese patients with several autoimmune diseases, hypertrophic cardiomyopathy, and Hodgkin's disease.
The possible significance of the autologous MLR, its relationship to in vivo immunoregulatory mechanisms, and the possible role of breakdown of autoimmunoregulation in the oncogenic process of certain lymphoproliferative and autoimmune diseases in man are discussed.
These results indicate that autoimmunity is transient in Japanese IDDM, but persistent in Chinese and Filipinos, and that it is too early to postulate in general that Bf-IDDM association in general populations is stronger than HLA-IDDM association.
It is probable that while interaction between certain HLA-DR3 and DR4-containing supratypes is important in conferring susceptibility to Type 1 diabetes, other manifestations of autoimmunity are associated with supratypes containing C4AQ0, and in particular the diabetogenic supratype HLA-B8-C4AQ0-C4B1-BfS-DR3.
The distribution of immunoglobulin allotypes of the Gm and Km systems was examined in 51 patients with antinuclear antibodies (ANA), which reacted with two saline-extractable non-DNA nuclear antigens, anti-La (SS-B) and anti-RNP, which characterize certain multisystem autoimmune diseases.

Genetic deficiency of the second component of complement (C2) is the most common complement-deficiency state among Western Europeans and is frequently associated with autoimmune diseases.
The distribution of cases within families was compatible with autosomal recessive inheritance, making it plausible to test hypotheses about the disease risk of heterozygote carriers of putative CVID genes by comparing the frequency of autoimmune disorders and cancer in 1033 adult blood relatives to that in 566 spouse controls.
We studied glucagon responses to OGTT and insulin and arginine stimulation in 12 out of 21 patients who were found positive for alpha cell autoantibodies (ACA) during routine screening procedures for autoimmunity in a group of 4080 individuals.
The evidence suggests that T cells can produce TNF and have the potential to deliver by themselves the dual and synergistic signals of TNF/LT and IFN-gamma to target cells, a process which may be of importance in the pathogenesis of human autoimmunity.

Approximately 90% of backcross mice with disease carried the NZW H-2z locus compared with 16% of mice without disease; nearly 90% of H-2d/z mice expressed severe autoimmune disease.
It is proposed that during EBV infection, there are multiple copies of the EBERs available to bind to the La ribonucleoprotein and when infection occurs in subjects who have an impaired T cell-mediated response to EBV, and who are genetically predisposed to autoimmunity, there is loss of immunological tolerance to La with production of anti-La (SS-B).
Deregulation of the expression of these interleukins was shown to be responsible for various diseases, such as i) IL-4 vs. immediate type hypersensitivity and ii) IL-6 vs. autoimmunity and multiple myelomas.

In vivo-activated interleukin 2 receptor-positive T lymphocytes (Tac cells) are demonstrable and the autologous mixed leukocyte reaction (AMLR) is impaired in several autoimmune diseases, including type 1 insulin-dependent diabetes mellitus (IDDM).
