The PTPN22 C1858T functional polymorphism and autoimmune diseases--a meta-analysis.
OBJECTIVE To assess whether combined evidence shows the association between the protein tyrosine phosphatase non-receptor 22 (PTPN22) C1858T polymorphism and autoimmune diseases, and to summarize the effect size of the polymorphism associated with susceptibility of autoimmune diseases. METHODS We surveyed studies on the PTPN22 C1858T polymorphism and autoimmune diseases using comprehensive Me...
متن کاملAutoimmune Variant PTPN22 C1858T Is Associated With Impaired Responses to Influenza Vaccination.
High-affinity-antibody production, T-cell activation, and interferon upregulation all contribute to protective immunity that occurs in humans following influenza immunization. Hematopoietic cell-specific PTPN22 encodes lymphoid phosphatase (Lyp), which regulates lymphocyte antigen receptor and pattern recognition receptor (PRR) signaling. A PTPN22 variant, R620W (LypW), predisposes to autoimmun...
متن کاملAntinuclear antibodies (ANA) in a Colombian cohort of pediatric patients with autoimmune diseases (PAID)
Results 363 patients were included. 66% had JIA, 11% JSLE, 7% juvenile undifferentiated autoimmune disease(JUAD), 4% Scleroderma, 4% JDM, 1% uveitis ANA + and a group of other PAID 11%. ANA positivity varies according to the subtype of JIA from 0-68%. Positive AAN: JSLE 93%, scleroderma 85%, JDM 63%. Most JUAD had ANA + at low titers. A heterogeneous group of other PAID showed a variable titers...
متن کاملThe Role of PTPN22 C1858T Gene Polymorphism in Diabetes Mellitus Type 1: First Evaluation in Greek Children and Adolescents
Type 1 diabetes mellitus (T1DM) is an autoimmune multifactorial disease. Protein tyrosine phosphatase nonreceptor type 22 (PTPN22) gene encodes lymphoid-specific tyrosine phosphatase (Lyp), an inhibitor of T cell activation. PTPN22 C1858T polymorphism was associated with T1DM in populations of Caucasian origin. The aim of this study was the investigation for the first time of the association of...
متن کاملImmunofluorescence Pattern of Autoimmune Bullous Diseases in Iranian Patients
Background & Objective: Autoimmune bullous diseases are associated with autoimmunity against structural components in the skin and mucous membranes. Autoantibodies are against the intercellular junctions in pemphigus disease and hemidesmosomal unchoring complex in pemphigiod diseases and epidermolysis bullosa aquisita. The tissue-bound and circulating serum autoantibodies can be detect...
