auto-reactive cells-mediated immune responses are responsible for the current tissue damages during autoimmunity. accordingly, functional modulation of auto-reactive cells has been a pivotal aim in many of recent studies. in the current study, we investigated the possibility for insertion of regulatory molecules onto auto-reactive cells through exosomal nano-shuttles as a novel approach for phe...

background: autoimmune type 1 diabetes mellitus is caused by t-cell mediated immune destruction of the insulin-producing β-cell in pancreatic islets of langerhans. specificity of the auto-antibodies and of the auto-reactive t-cells has been investigated, in which several auto-antigens were proposed. objective: to determine whether glutamic acid decarboxylase (gad) feeding would induce oral tole...

The distinct properties of allo-reactive T-cell repertoires are not well understood. To investigate whether auto-reactive and encoded properties, we used dextramer enumeration, enrichment, single-cell receptor (TCR) sequencing multiparameter analysis. We found T-cells differed in mean ex vivo frequency which was antigen dependent. Allo-reactive showed clear differences TCR architecture, with en...

Studies on autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) and its mouse model - both caused by mutant AIRE - have greatly advanced the understanding of thymic processes that generate a self-tolerant T-cell repertoire. Much is now known about the molecular mechanisms by which AIRE induces tissue-specific antigen expression in thymic epithelium, and how this leads to nega...

The isolation of human monoclonal antibodies (hmAb) has emerged as a versatile platform in a wide variety of contexts ranging from vaccinology to therapeutics. In particular, the presence of high titers of circulating auto-antibodies is implicated in the pathology and outcome of autoimmune diseases. Therefore, the molecular characterization of these hmAb provides an avenue to understanding the ...

The effects of antimalarials, chloroquine and quinacrine, on the generation of reactive oxygen species were examined both in polymorphonuclear leucocytes and in the xanthine-xanthine oxidase system. Antimalarials showed inhibitory effects on the production of reactive oxygen species probably by affecting cell functions, such as membrane phospholipid methylation. It is suggested that antimalaria...

BACKGROUND Although human mesenchymal stem cells (hMSCs) have been tested in ischemic cardiomyopathy, few studies exist in chronic nonischemic dilated cardiomyopathy (NIDCM). OBJECTIVES The authors conducted a randomized comparison of safety and efficacy of autologous (auto) versus allogeneic (allo) bone marrow-derived hMSCs in NIDCM. METHODS Thirty-seven patients were randomized to either ...
