Type 1 diabetes mellitus (T1D) remains the most intensively studied, and thus the best paradigm, of MHC-associated diseases. Accumulating evidence suggests that MHC susceptibility for T1D is recessive, with susceptibility alleles more common than protective alleles. Updated allele-level and nucleotide sequence analysis of MHC class II T1D susceptibility markers of conserved extended haplotypes ...
BACKGROUND AND OBJECTIVE To improve the efficacy and safety of tolerance induction for food allergies, identifying the tissues responsible for inducing intestinal inflammation and subsequent oral tolerance is important. We used OVA23-3 mice, which express an ovalbumin-specific T-cell receptor, to elucidate the roles of local and systemic immune tissues in intestinal inflammation. METHODS AND ...
The severity and intensity of autoimmune disease in immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) patients and in scurfy mice emphasize the critical role played by thymus-derived regulatory T cells (tTregs) in maintaining peripheral immune tolerance. However, although tTregs are critical to prevent lethal autoimmunity and excessive inflammatory responses, their suppress...
The upper digestive tract is routinely scoped for several causes of malabsorption, and the number of duodenal biopsy specimens has increased notably in the last 10 years. Gluten-sensitive enteropathy (GSE) is an autoimmune disease, which shows an increasing prevalence worldwide and requires a joint clinico-pathological approach. The classical histopathology of GSE with partial or total villous ...
The Scurfy mutation of the FoxP3 gene (FoxP3(sf)) in the mouse and analogous mutations in human result in lethal autoimmunity. The mutation of FoxP3 in the hematopoietic cells impairs the development of regulatory T cells. In addition, development of the Scurfy disease also may require mutation of the gene in nonhematopoietic cells. The T cell-extrinsic function of FoxP3 has not been characteri...
Diarrheal disease is a major cause of childhood morbidity and mortality worldwide. Chronic enteropathy with subsequent persistent diarrhea and associated vicious cycles of malnutrition, increased gut permeability and secondary immunodeficiency are particularly devastating in the childhood population. The major causes of chronic enteropathy differ significantly between developed countries and de...
We report the case of a 29 year old woman with a protein losing enteropathy caused by systemic lupus erythematosus presenting with periorbital oedema. Only three other cases of protein losing enteropathy due to systemic lupus erythematosus have been described, two of which were thought to be because of a primary enteropathy, although the exact pathogenesis was unknown. We suggest that both the ...
Protein-losing enteropathy is the manifestation of a diverse set of disorders, and it is characterized by the excessive loss of plasma proteins into the affected portions of the gastrointestinal tract, and this results in hypoalbuminemia. We report here on a case of severe protein-losing enteropathy with the typical clinical features of hypoalbuminemia, dependent edema and increased alpha 1-ant...
Tufting enteropathy is an autosomal recessive congenital enteropathy presenting with early-onset severe intractable diarrhea. It presents with watery diarrhea that develops in the first days after birth and persists despite bowel rest. Growth is impaired, and most patients require total parenteral nutrition. The histological characteristic of tufting enteropathy is the presence of epithelial tu...
