Udgivelsesdato: 1999-Oct Immunoglobulin A and IgM are subjected to epithelial transport only when they are produced as polymers with incorporated J chain. Immunocytes containing various Ig isotypes and associated J chain in gastric mucosa, as well as

Serum samples from 458 consecutive adult patients with intestinal symptoms and/or suspected food intolerance were examined for IgG and IgA antibody activities to gluten, egg, and cow's milk antigens by an enzyme-linked immunosorbent assay (ELISA). In

Relation between T cell number and epithelial HLA class II expression quantified by image analysis in normal and inflamed human gastric mucosa

Autor: K Valnes, Per Brandtzaeg, H S Huitfeldt

Publikováno v: Gut. 31(6)

Epithelial expression of HLA class II determinants and the number of lamina propria and intraepithelial T cells were quantified in gastric body mucosa by means of paired immunofluorescence staining which was subjected to computerised image analysis.

The secretory antibody system depends on local production and selective epithelial transport of polymeric immunoglobulin A (pIgA) and immunoglobulin M (pIgM). To this end there is a fascinating co-operation between the local immune system and the gla

Subclass distribution of mucosal IgG-producing cells in gastritis

Autor: K Valnes, P Brandtzaeg

Publikováno v: Gut. 30:322-326

IgG-mediated immune reactions are probably involved in the maintenance of gastritis and glandular atrophy; the mucosal IgG-subclass pattern may therefore influence the effect of local hypersensitivity mechanisms. In this study the proportions of IgG1
