The repertoire of IgG antibody responses to infection and vaccination varies depending on the characteristics of the immunogen and the ability of the host to mount a protective immune response. Chronic hepatitis B virus (HBV) infections are marked by persistent infection and immune tolerance to vaccin...
Three groups have recently published observations relevant to the pathogenesis of AIH. Renand et al. describe a rare population of CD4 cells, with a memory PD-1 + CXCR5 − CCR6 − CD27 + phenotype, reactive with SLA and only present in patients positive for anti-SLA ...
Autoimmune hepatitis is a chronic inflammatory hepatic disorder which may cause liver fibrosis. Appropriate treatment of autoimmune hepatitis is therefore important. Adult stem cells have been investigated as therapies for a variety of disorders in lates
(IgG) and positive circulating autoantibodies, and histologically by interface hepatitis. It affects all ages, including young children. AIH is subdivided into two types according to the serological profile: type 1 (AIH-1) is characterized by anti-nuclear antibody (ANA) and/or anti-smooth muscle...
Four patients in this group exhibited concomitant AHAb and AHAg. Investigations of liver tissue elute reveal that patients with advanced alcoholic hepatitis or active alcoholic cirrhosis have AHAg-reactive immune complexes containing IgG and IgA immunoglobulins. 展开 ...
Hepatitis A virus and cytomegalovirus serology indicated positive IgG. Serum electrophoresis showed marked polyclonal hypergammaglo- bulinemia with elevated gammaglobulin level to 20.9 g/L (8.0–13.5 g/L) including 17.5 g/L IgG (6.7–12.4 g/L) and 2.0 g/L IgM (0.6–1.6 g/L). The ...
3c), but trended towards a higher frequency of class-switched IgG+ IgM- B cells (Fig. 3d) and a higher frequency of activated memory B cells (Fig. 3e). However, none of these observations reached statistical significance. Fig. 3: B cell antigen specific phenotyping in each vaccine arm....
Insufficient sample volume also led to a small number of ‘indeterminate’ results where a patient's infection status could not be ascertained. For example, samples from three patients were reactive for anti-HCV IgG on the screening assay, but there was insufficient sample for HCV RNA and ...
