In this article, we confirm the positive association of acid phosphatase locus 1 (ACP1)*A/adenosine deaminase locus 1 (ADA1)*2 gametic type with type 1 diabetes (T1D) previously reported and show a negative correlation between the frequency of this gametic type with past malarial morbidity in Sardinia.
Antibodies to glutamic acid decarboxylase (GAD65 [GADA]) and the intracellular portion of protein tyrosine phosphatase (IA-2(ic) [IA-2A]) were measured by similar, but not identical, methods in samples from participants in the Type 1 Diabetes Genetics Consortium (T1DGC).
The R620W polymorphism in the protein-tyrosine-phosphatase nonreceptor type 22 gene (PTPN22) confers susceptibility to type 1 diabetes (T1D) and other autoimmune diseases.
This investigation based on the biological effects of ACP1 and ADA1 on the immune system and on the known biochemical interaction between the two systems showed a significant interaction between the two system concerning susceptibility to type 1 diabetes.
ACP1 is also associated with Crohn's disease and type 1 diabetes: the relationship between this class (Th1) of immunological diseases and ACP1 depends on gender.
A comparative analysis of the data on Type 1 diabetes with previously obtained data on Type 2 diabetes shows an opposite pattern of relationship between ACP1 and metabolic parameters.
We examine here the interaction between smoking and ACP1 as a mediator of susceptibility to diabetic retinopathy in a sample of puerperae with type 1 diabetes.
In a registry-based group of 525 recent-onset IDDM patients <40 years old we investigated the possible interactions of a CTLA-4 gene A-to-G transition polymorphism with age at clinical disease onset and with the presence or absence of established genetic (HLA-DQ, INS VNTR) and immune disease markers (autoantibodies against islet cell cytoplasm (ICA); insulin (IAA); glutamate decarboxylase (GAD65-Ab); IA-2 protein tyrosine phosphatase (IA-2-Ab)) determined within the first week of insulin treatment.In new-onset IDDM patients.
Cloning and characterization of islet cell antigen-related protein-tyrosine phosphatase (PTP), a novel receptor-like PTP and autoantigen in insulin-dependent diabetes.
