Antibody-mediated rejection is well established for renal allografts but remains controversial for lung allografts. Cardinal features of antibody-mediated rejection in renal allografts include antibodies to donor human leukocyte antigen (HLA) and evidence for antibody action, such as complement activation demonstrated by C4d deposition. We report a lung allograft recipient with circulating anti...
Immunoglobulin A (IgA) is the most abundant antibody isotype in humans and anti-HLA IgA was found sera of transplant recipients. Focusing on patients awaiting kidney re-transplantation, we tested impact anti-HLA-class I/II antibodies graft survival. We analyzed 276 with 238 without allograft failure. Eight motives Fcα receptor (FCAR) Fcγ were The distribution IgA1/A2 IgG differed significantly ...
Glycyrrhizin has been clinically used as an anti-allergic agent, but its mechanism remains unknown. This study was undertaken to examine the effect of glycyrrhizin on thymolytic and immunosuppressive action of cortisone in normal rabbits and adrenalectomized rats. Immunization was performed by injection of bacterial a-amylase emulsified in Freund's incomplete adjuvant. Antibody titer of the ser...
background: the ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. the aim of this study was purification of mouse igg2a and production of polyclonal antibody against purified mouse igg2a subclass. materials and methods: mouse igg2a was purified by proa affinity. verification method of the purified antibody was sds-...
BACKGROUND Chronic allograft rejection manifested as bronchiolitis obliterans syndrome (BOS) is the leading cause of late death after lung transplantation. Although increasing evidence suggests an association between anti-human leukocyte antigens (HLA) antibodies and chronic rejection of kidney or heart allografts, the clinical significance of anti-HLA antibodies in lung recipients is less clea...
background: there is a controversy about the relation between anti-hepatitis b (anti-hbs) antibody level and obesity. we designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. methods: in this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. cases were selected from a referral clinic for obesity and a referral hepa...
We performed a two-stage genome-wide association study (GWAS) of antibody titer in 3614 hepatitis B vaccine recipients from Indonesia's Riau Archipelago, leading to the identification of at least three independent signals within the human leukocyte antigen (HLA) complex. These appear to implicate HLA-DR [rs3135363; P= 6.53 × 10(-22); odds ratio (OR) = 1.53, 95% confidence interval (CI) = 1.35-1...
The diagnosis of HIV infection is based on screening of HIV antibodies and confirmed by a more specific supplementary test. The most common confirmation test is Western blot, which is expensive, time consuming and subject to technical skill. The present study was carried out to evaluate whether the anti-HIV-1 antibody titer is valid as a supplementary test for diagnosis of HIV-1 infection. Anti...
OBJECTIVE The functional role of HLA class II molecules in the pathogenesis of rheumatoid arthritis (RA) is unclear. HLA class II molecules are involved in the interaction between T and B lymphocytes required for long-lived B cell responses and generation of high-affinity IgG antibodies. We undertook this study to investigate the relationship between HLA class II gene polymorphisms and RA-speci...
