After integration into the endoplasmic reticulum (ER) membrane, ER-resident membrane proteins must be segregated from proteins that are exported to post-ER compartments. Here we analyze how human Gaa1 and PIG-T, two of the five subunits of the ER-localized glycosylphosphatidylinositol transamidase complex, are retained in the ER. Neither protein contains a known ER localization signal. Gaa1 is ...

Cells from eight patients with adult T cell leukemia (ATL) and from four patients with non-ATL were examined to see if the T3 antigen of these cells could be modulated in vitro. We found a low density of T3 antigen and the presence of Tac antigen on cells from all patients with ATL. The density of T3 antigen on non-ATL cells was normal, and Tac antigen was not detected. Modulation of T3 antigen...

Anti-Tac monoclonal antibody, which blocks the membrane binding and action of human T-cell growth factor (TCGF), is strongly proposed to recognize TCGF receptor. We have demonstrated that anti-Tac antibody reacted with leukemic cells from patients with adult T-cell leukemia (ATL) and reacted with T-cell lines established from ATL cells. Although antigenic modulation, or down-regulation, of Tac ...

Soluble interleukin 2 receptor (sIL-2R) levels reflect mononuclear cell activation and are elevated in a variety of autoimmune, neoplastic and infectious conditions. Several investigators have studied sIL-2R levels in patients with Type I diabetes mellitus (IDDM), but results have been conflicting. Our primary objective in this study was to compare sIL-2R levels of children and adolescents with...

NOD-scid.Il2rg(null) (NSG) mice are currently being used as recipients to screen for pathogenic autoreactive T cells in type 1 diabetes (T1D) patients. We questioned whether the restriction of IL-2R γ-chain (Il-2rγ)-dependent cytokine signaling only to donor cells in NSG recipients differently influenced the activities of transferred diabetogenic T cells when they were introduced as a monoclona...

We investigated the population structure of 208 Candida dubliniensis isolates obtained from 29 patients (25 human immunodeficiency virus [HIV] positive and 4 HIV negative) as part of a longitudinal study. The isolates were identified as C. dubliniensis by arbitrarily primed PCR (AP-PCR) and then genotyped using the Cd25 probe specific for C. dubliniensis. The majority of the isolates (55 of 58)...

Introduction Type 1 diabetes mellitus (T1D) (OMIM 222100) is an organ-specific and autoimmune disease that primarily affects children and adolescents. It is caused by destruction of the beta cells of Langerhans of the pancreas that secrete insulin, which occurs through the autoimmune processes. Therefore, the affected patients have to use insulin throughout their lives.1 The clinical symptoms o...

background because il2ra is considered a predisposing factor in the incidence of both type i diabetes and multiple sclerosis (ms), and considering that both are autoimmune diseases, some studies suggest a correlation between type i diabetes and ms. objectives the aim of this study was to examine the prevalence of type i diabetes among people with ms. patients and methods the study subjects comp...

1.1 Background and status of knowledge Type 1 Diabetes (T1D) is a T-cell mediated autoimmune disease that develops in genetically susceptible individuals whose immune system destroys the majority of insulin-secreting βcells in pancreatic islets (Eizirik et al., 2009). The incidence of T1D has increased more than twoto threefold over the past half century, the most striking example being Finland...
