Biliary secretion of antibody to dextran following oral immunization with dextran B512



Biliary secretion of antibody to dextran following oral immunization with dextran B512



Immunopharmacology. 29(3): 251-259



Anti-dextran in bile was induced to high levels by oral immunization with dextran B512. IgM anti-dextran were dominant in serum, whereas IgG anti-dextran was dominant in bile. The binding properties of these IgM and IgG antibodies were different, as determined by ELISA with several dextrans. Splenocytes produced equal amounts of IgG and IgM antidextran but cells from mesenteric lymph nodes (MLN) and Peyer's patches produced mainly IgG anti-dextran. Differences were observed among different strains of mice in their ability to produce anti-dextran in serum and bile upon immunization with dextran. BALB/c mice, which are intermediate responders in terms of their serum antibody levels, produced high levels of anti-dextran in bile. C3H/He and C57BL/6, which are high responders in terms of serum antibody levels, had intermediate responses in bile. DBA/2, which are low responders in terms of serum antibody levels, showed low responses in bile. The results provide further evidence of the existence of anti-dextran producing cells. These results indicate that B cells in systemic and mucosal-associated lymphoid tissues from BALB/c, C3H/He, C57BL/6 and DBA/2 mice respond differently to oral immunization with dextran B512.
