AIM To establish the relationship of protein tyrosine phosphatase non-receptor type 2 and 22 (PTPN2/22) polymorphisms and mycobacterial infections in Crohn's disease (CD). METHODS All 133 subjects' blood samples were genotyped for nine single nucleotide polymorphisms (SNPs) in PTPN2/22 using TaqMan™ genotyping, while the effect of the SNPs on PTPN2/22 and IFN-γ gene expression was determined ...

OBJECTIVES To increase understanding of the aetiology and pathogenesis of rheumatoid arthritis (RA), genetic and environmental risk factors for RA subsets, defined by the presence or absence of different anticitrullinated protein/peptide antibodies (ACPAs) targeting citrullinated peptides from α-enolase, vimentin, fibrinogen and collagen type II, were investigated. METHODS 1985 patients with ...

مقدمه: سقط مکرر به ختم بارداری بیش از دو بار اطلاق می‌شود. عوامل متعددی در ایجاد سقط مکرر دخیل هستند، وجود اختلال در عملکرد سیستم ایمنی منجر به دفع جنین می‌شود. آنزیم پروتئین تیروزین فسفاتاز بافت لنفاوی (Lyp) که توسط ژن PTPN22 کد می‌شود، نقش حیاتی در تنظیم و تعادل پاسخ‌های ایمنی دارد؛ به‌تازگی پلی‌مورفیسم rs2488457که در ناحیه پروموتر این ژن قراردارد کشف شده ‌است، محتمل است این پلی‌مورفیسم با تغ...

The recent article by Negro et al represents a thorough investigation into the effect of Lyp, the gene product of PTPN22, on BCR signaling in the pathogenesis and progression of chronic lymphocytic leukemia (CLL).1 This study shows that increased Lyp enhances Akt, a serine/threonine kinase involved in cell survival and tumorigenesis, despite a negative effect on proximal BCR signaling molecules...

The papers in presentation group 2 of Genetic Analysis Workshop 15 (GAW15) conducted association analyses of rheumatoid arthritis data. The analyses were carried out primarily in the data provided by the North American Rheumatoid Arthritis Consortium (NARAC). One group conducted analyses in the data provided by the Canadian Rheumatoid Arthritis Genetics Study (CRAGS). Analysis strategies includ...
