The action of interleukin-4 on antigen-specific IgG1 and IgE production by interaction of in vivo primed B cells and carrier-specific cloned Th2 cells.
The production of anti-trinitrophenyl (TNP) antibodies of different isotypes from in vivo primed B cells was studied using the plaque-forming cell method. It was shown that these B cells secrete anti-trinitrophenyl antibodies of different isotypes only in the presence of Th2 cells specific for keyhole limpet hemocyanin (KLH) and the hapten-carrier conjugate TNP-KLH. Lipopolysaccharide-stimulated primed B cells without cells from the Th2 clone did not produce anti-TNP-specific IgG1 or IgE antibodies even in the presence of the hapten-carrier antigen TNP-KLH. Supernatants from these Th2 clones cultured with antigen-presenting cells and the complete antigen were unable to activate primed B cells for antibody secretion. Cognate interaction between primed B cells and carrier-specific Th2 cells is a prerequisite for hapten-specific IgG1 or IgE production. Anti-IL-4 antibody inhibited secretion of anti-hapten IgE antibody. Therefore, for production of anti-hapten antibody of the IgE isotype IL-4 is also necessary.
