Characterization of cytotoxic autoantibodies reacting with a cytotoxic/suppressor T-lymphocyte subset in myocarditis

The Relationship between insulin variable number of tandem repeats (INS-VNTR) -23 A/T and cytotoxic T-lymphocyte associated protein-4 (CTLA-4) +49 A/G polymorphisms with islet autoantibodies in persons with diabetes

  Background: Both genetic and environmental factors are important in pathogenesis of diabetes. Non HLA (Human Leukocyte Antigen) genes such as INS-VNTR and CTLA-4 in addition of HLA genes have influence on genetic susceptibility for diabetes mellitus. In this study the association of +49 A/G CTLA-4 and -23 A/T INS-VNTR polymorphisms with diabetes and their association with islet auto...

Increased cytotoxic T-lymphocyte-mediated cytotoxicity predominant in patients with idiopathic thrombocytopenic purpura without platelet autoantibodies.

association of 1661a/g cytotoxic t lymphocyte antigen-4 (ctla-4) gene polymorphism with a clinical subset of iranian children with systemic lupus erythematosus

results our study showed that there were no statistically significant differences in the allele and genotype frequencies of -1661 a/g snp between patients with sle and healthy controls (p > 0.05). conclusions in conclusion, we found no association between snp-1661 a/g of the ctla-4 promoter region and susceptibility to sle in our population. objectives to evaluate the potential influences of co...

Takayasu myocarditis mediated by cytotoxic T lymphocytes.

A 15-year-old Japanese man was referred for evaluation of heart failure. Conventional heart failure therapy had little effect, and severe left ventricular dysfunction as well as elevated erythrocyte sedimentation rate persisted. Magnetic resonance angiography showed aortic dilatation with wall thickening characteristic of Takayasu's arteritis. An endomyocardial biopsy specimen revealed infiltra...

A SURVEY OF CELLULAR IMMUNITY, TOTAL T-LYMPHOCYTE, T-ACTIVE , B-LYMPHOCYTE A ND T-CELL FUNCTION IN RELATION TO PHYTOHEMAGGLUTININ (PHA) IN THALASSEMIC PATIENTS

The aim of this study was to evaluate the immune system and lymphocyte function in 41 Iranian β-thalassemic patients and 50 controls, ages ranging from 2 to 18 years. The patients consisted of 20 splenectomized and 21 non-splenectomized patients. They were treated with Desferal, and had received repeated blood transfusion. Laboratory investigations included measurement of total T lymphocyt...
