Adjuvant Effects of Amorphous Silica and of Aluminium Hydroxide on IgE and IgGsub1/subAntibody Production in Different Inbred Mouse Strains

摘要

The adjuvant effects of an amorphous silica (Aerosil) and of Al(OH)3 on primary and secondary IgE and IgG1 immune responses to small doses of OA were studied comparatively in BALB/c, C57BL, DBA/1, AKR, DBA/2 and SJL inbred mouse strains. During the primary response, all mouse strains produced both IgG1 and IgE antibodies when antigen was given with Al(OH)3, whereas only DBA/1, BALB/c and DBA/2 mice produced IgG1 and/or IgE antibodies when Aerosil was used as the adjuvant. A booster effect, higher than that obtained by Al(OH)3, was induced by Aerosil in all mouse strains. The adjuvant effect of Aerosil was more selectively directed to the production of IgE antibody.
