Aim: B cell activating factor belonging to the tumour necrosis factor family (BAFF) and a proliferation inducing ligand (APRIL) are two tumour necrosis factor (TNF)-like cytokines that were found to be elevated in many autoimmune diseases. Anti-glomerular basement membrane (GBM) disease is a typical severe autoimmune disease characterized by raised serum anti-GBM antibodies. In this study we aimed to detect the serum levels of BAFF and APRIL in patients with anti-GBM disease, and their clinical significance was further analyzed.

In this study, a natural Chinese zeolite was anatomized using the mercury injection method, X-ray diffraction, and scanning electron micrographs. The kinetic process of ammonium adsorption onto the zeolite was best described by the pseudo second order model; the adsorption equilibrium data fitted better to the Freundlich isotherm; and the exchange between ammonium and alkali/alkaline earth cations was in the order of Na(+) > Ca(2+) > K(+) > Mg(2+).

Background And Objectives: Linear epitopes on the Goodpasture autoantigen involved in human anti-glomerular basement membrane (GBM) disease are not fully defined. This study investigated the linear epitopes recognized by circulating antibodies in anti-GBM patients, aiming to identify the potential nephrogenic linear epitopes and their clinical significance.
Design, Setting, Participants, & Measurements: Sixty-eight patients with anti-GBM disease were enrolled.
Background: The pathophysiological significance of variable region glycosylation of autoantibodies is still unclear. In the current study, the influence of the variable region N-linked oligosaccharides on the reactivity of three autoantibody specificities was investigated with Sambucus nigra agglutinin (SNA), which mainly binds to oligosaccharides with terminal α2, 6-linked sialic acid on the variable region of IgG.
Methods: Twenty-seven patients with serum positive anti-neutrophil cytoplasmic autoantibodies (ANCA) against myeploperoxidase (MPO) or proteinase 3 (PR3), or autoantibodies against glomerular basement membrane (GBM) were included.
In the current study, whether myeloperoxidase (MPO)-catalyzing reaction could influence the antigenicity of MPO was investigated. Hypochlorite acid, the main product of the catalytic reaction, could lower the binding between MPO-antineutrophil cytoplasmic antibodies (ANCA) and MPO when the available chlorine was higher than 0.031×10(-3) g/l.

The low incidence and fulminant course of disease preclude a large randomized controlled study to define the benefits of any given therapy. We conducted a retrospective survey of 221 consecutive patients seen from 1998 to 2008 in our hospital, and report here the patient and renal survival and the risk factors affecting the outcomes.
View Article and Find Full Text PDFAim: Cases with anti-glomerular basement membrane (GBM) disease have been reported with linear deposit of immunoglobulin G (IgG) along GBM, but have undetectable anti-GBM antibodies in circulation by enzyme linked immunosorbent assays (ELISA). We speculated that the structure of the antigens recognized by these antibodies may contribute to the negative results of ELISA.
Methods: Sera from four patients were collected, with typical linear deposit of IgG along GBM but no anti-GBM reactivity by commercial ELISA kits.
Antiglomerular basement membrane (anti-GBM) disease is an autoimmune disorder that mostly presents as raised titers of antibodies against the GBM, rapidly progressive glomerulonephritis and pulmonary hemorrhage. The disease is caused by antibodies against noncollagenous domain of α3 chain of type IV collagen, which contains the epitopes E(A) and E(B). The humoral and cellular immunity contributing to the initiation of anti-GBM disease has been extensively studied as a model for autoimmune diseases, although most of the data come from animal studies.

In our previous study, it was demonstrated that HLA-DRB1*1501 was strongly associated with anti-GBM disease in Chinese. However, the association of anti-GBM disease and other HLA class II genes, including HLA-DQB1, -DQA1,-DPB1 alleles, has rarely been investigated in Asian, especially Chinese patients.

Background: One of the potential strategies for preventing cancers is using food-based natural products to induce cytoprotective enzymes including phase II and antioxidative enzymes that act in concert to detoxify and eliminate harmful reactive intermediates formed from carcinogens. The antioxidant response element (ARE), which is activated upon binding of the nuclear factor E2-related protein 2 (Nrf2) transcription factor protein, has been identified in the regulatory regions of numerous genes encoding cytoprotective enzymes. Herein, we summarized the current body of knowledge regarding Nrf2 regulation as well as highlighted the Nrf2/ARE activators from natural products, which will potentially be used as chemopreventive agents for cancer patients.
