Transfer of Antibody Production with Cells from Bursa of Fabricius
F(1) hybrid chicks isogenic for the strong B histocompatibility locus and for most weak H-loci were X-irradiated on day 1 after hatching, injected intraperitoneally on day 2 with dispersed cells of bursa, spleen, or thymus from 4- or 10-wk-old F(1) hybrid donors, and immediately challenged by the same route with either Brucella abortus, sheep erythrocytes, or a mixture of both together. The agg...
متن کاملPeptides from the Bursa of Fabricius Associated with Suppression of Mitogen Stimulated DNA - Synthesis in Bursa of Fabricius Cells Belong to Intracellular Proteins
Previous reports from our laboratory have demonstrated that an reverse phase HPLC (rpHPLC) fraction obtained from extracts of the chicken bursa of Fabricius posses both in vitro anti-steroidogenic activity on avian and mammalian cells and suppression on mitogen stimulated DNA-synthesis in chicken BF cells. Utilizing YM cut-off membranes the bioactive fraction appears to be between ~3-5kDa. Howe...
متن کاملEffect of catecholamines on bursa of fabricius in chicken.
Effect of catecholamines are studied on the bursa of fabricius of chicken. It is found that in epinephrine (E) treated chicken, the lymph follicles are slightly decreased in size. Some amount of nuclear pycnosis is visible in E and norepinephrine (NE) treated chicken. There is no change in the bursa weight and histology in NE treated groups. No deviation is observed in the level of DNA, RNA, to...
متن کاملEphrin Receptor Expression in the Embryonic Bursa of Fabricius
Utilizing degenerate PCR primers complementary to conserved regions within the kinase domain of Receptor Tyrosine Kinase (RTK) genes, the goal was to compare the full complement of RTK expressed (mRNA level) between two developmental stages of bursal B-cells. We identified 21 different RTK cDNAs out of a total of 235 cDNAs sequenced between the two B-cell stages. The dataset revealed the expres...
متن کاملchTLR4 pathway activation by Astragalus polysaccharide in bursa of Fabricius
Background: The Toll-like receptor 4 (TLR4) pathway involves in the pathogen recognition and defense against infection in mammals. Considering that avian and mammalian TLR are differentially mediated, the action of a natural product on avian TLR4 pathway was unclear. High, medium and low doses of Astragalus polysaccharide (APS), were treated the chicken at 7-days-old age by gavage. The sIgA lev...
