Human AIP blocking peptide

Based on a first-principles computational method treating the local Coulomb repulsion of U and Hund's coupling of I separately, we investigate the effects of these important interactions on the electronic and magnetic structures of a layered ferromagnetic semiconductor CrGeTe3. We show that explicit inclusion of a density functional for the coupling I is critical to obtain proper bandgaps of a single-layer and bulk systems with a reasonable U, unlike a usual approximation treating those together. After obtaining reliable U and I, we also study the effects of strain on its energy gap. Within 2% of tensile and compressive strains, respectively, there is no strain-induced semiconductorto-metal transition, contrary to the results without I, thus highlighting important roles of exchange interactions.

IgG4-related disease (IgG4-RD) is a multi-organ autoimmune disease characterized by elevated serum IgG4 concentration. Although serum IgG4 concentration is widely used as a biomarker for IgG4-RD and type 1 autoimmune pancreatitis (AIP), a pancreatic manifestation of IgG4-RD, a significant number of patients have normal serum IgG4 levels, even in the active phase of the disease. Recently, we reported that the development of experimental AIP and human type 1 AIP is associated with increased expression of IFN-alpha and IL-33 in the pancreas. In this study, we assessed the utility of serum IFN-alpha and IL-33 levels as biomarkers for type 1 AIP and IgG4-RD. Serum IFN-alpha and IL-33 concentrations in patients who met the diagnostic criteria for definite type 1 AIP and/or IgG4-RD were significantly higher than in those with chronic pancreatitis or in healthy controls. Strong correlations between serum IFN-alpha, IL-33, and IgG4 concentrations were observed. Diagnostic performance of serum IFN-alpha and IL-33 concentrations as markers of type 1 AIP and/or IgG4-RD was comparable to that of serum IgG4 concentration, as calculated by the receiver operating characteristic curve analysis. Induction of remission by prednisolone treatment markedly decreased the serum concentration of these cytokines. We conclude that serum IFN-alpha and IL-33 concentrations can be useful as biomarkers for type 1 AIP and IgG4-RD.
