Abstract

Autoreactive B cells are actively tolerized to more abundant self-antigens by a series of checkpoints involving receptor editing, deletion, anergy and competition for growth factors. In contrast, B cells reactive against rare, sequestered or tissue specific self-antigens remain functionally naïve. During an immune response, the autoimmune danger from these cells is countered by a variety of mechanisms comprising control of self-antigen presentation, limitation of immunogenic and tolerogenic costimuli including T cell help, homeostatic control of growth and strict regulation of germinal centre reactions. In this overview we consider how knowledge of these checkpoints may be used to gain a better understanding of transplant tolerance and the generation of alloantibodies.

Role of V1V2 and other human immunodeficiency virus type 1 envelope domains in resistance to autologous neutralization during clade C infection.

Biologically functional clade C envelope (Env) glycoproteins from the chronically (donor) and newly (recipient) infected partners of four heterosexual transmission pairs in Zambia were cloned and characterized previously. In each case, the donor viral quasispecies contained Envs that were resistant to autologous neutralization by contemporaneous plasma, while the recipient Envs were sensitive to neutralizing antibodies in this donor plasma sample. The donor Envs also varied in length, glycosylation, and amino acid sequence of the V1V2 hypervariable domain of gp120, while the recipient Envs were much more homogeneous. To assess the contribution of V1V2 to the neutralization phenotype of the donor Envs, V1V2 domains from neutralization-sensitive recipient Envs were replaced with donor V1V2 domains, and the autologous neutralization sensitivities of the chimeric Envs were evaluated using a virus-pseudotyping assay. Long donor V1V2 domains regulated sensitivity to autologous neutralization, although the effect was dependent on the Env background. Short donor V1V2 domains did not confer neutralization resistance. Primary sequence differences in V2 were also found to influence neutralization sensitivity in one set of recipient Envs. The results demonstrate that expansion of the V1V2 domain is one pathway to escape from autologous neutralization in subtype C Envs. However, V1V2-independent mechanisms of resistance also exist, suggesting that escape is multifaceted in chronic subtype C infection.

Proinsulin is encoded by an RNA splice variant in human blood myeloid cells.

Genes for peripheral tissue-restricted self-antigens are expressed in thymic and hematopoietic cells. In thymic medullary epithelial cells, self-antigen expression imposes selection on developing autoreactive T cells and regulates susceptibility to autoimmune disease in mouse models. Less is known about the role of self-antigen expression by hematopoietic cells. Here we demonstrate that one of the endocrine self-antigens expressed by human blood myeloid cells, proinsulin, is encoded by an RNA splice variant. The surface expression of immunoreactive proinsulin was significantly decreased after transfection of monocytes with small interfering RNA to proinsulin. Furthermore, analogous to proinsulin transcripts in the thymus, the abundance of the proinsulin RNA splice variant in blood cells corresponded with the length of the variable number of tandem repeats 5' of the proinsulin gene, known to be associated with type 1 diabetes susceptibility. Self-antigen expression by peripheral myeloid cells extends the umbrella of "immunological self" and, by analogy with the thymus, may be implicated in peripheral immune tolerance.

Quantitative assay of deletion or duplication genotype by capillary electrophoresis system: Application in Prader-Willi syndrome and Duchenne muscular dystrophy.

BACKGROUND: Deletions and duplications involving large DNA segments result in underexpression or overexpression, depending on the changes in allele dose, and are known to cause many common disorders. Detection of allele dose variations in the human genome is increasingly important in medical genetic diagnosis. METHODS: We used multiplex quantitative PCR coupled with capillary electrophoresis for accurate allele dose determination. In cases of Prader-Willi syndrome (PWS), a total of 24 patients with PWS, as well as 205 control individuals from the general population, were analyzed by use of multiplex quantitative PCR to amplify the FGFR2 gene, the KRIT1 gene, and the SNRPN gene simultaneously. In cases of Duchenne muscular dystrophy (DMD), we optimized the multiplex quantitative PCR to amplify 38 exons to analyze the DMD gene for rapid diagnosis of 12 DMD-affected males, 12 obligate carriers from families, and 50 unaffected female controls. RESULTS: We were able to unambiguously diagnose the deletion genotype in PWS patients and identify all deletion or duplication genotypes and carrier status in DMD-affected cases with 100% sensitivity and specificity. CONCLUSIONS: This report describes a novel single assay that can rapidly quantify allele dose to provide accurate clinical genetic diagnosis. This technique offers a valuable alternative for the rapid detection of genomic deletions or duplications and decreases costs because it does not require expensive fluorescent reagents.
