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.
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.
The R620W polymorphism in the protein-tyrosine-phosphatase nonreceptor type 22 gene (PTPN22) confers susceptibility to type 1 diabetes (T1D) and other autoimmune diseases.
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.
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).
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.
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.
Cloning and characterization of islet cell antigen-related protein-tyrosine phosphatase (PTP), a novel receptor-like PTP and autoantigen in insulin-dependent 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.
