Abstract

The role of CD86 in triggering of ascaris extract-specific IgE antibody response by lipopolysaccharide was studied. The simultaneous administration of anti-CD86 antibody with ascaris extract and lipopolysaccharide prevented the production of IgE antibody response to ascaris extract. CD86+ cells were detected in peritoneal cavities and spleens of mice injected intraperitoneally with lipopolysaccharide. CD86+ cells appeared in peritoneal cavities and spleens eight hours after lipopolysaccharide injection, and they were detectable for a week. CD86+ cells in peritoneal cavities and spleens were mainly surface Ig-positive B-cells and some Ig-negative cells. It was suggested that lipopolysaccharide induced the expression of CD86 mainly on B-cells, and that CD86+ cells induced by lipopolysaccharide injection might play an important role as antigen-presenting cells on triggering of ascaris extract-specific IgE antibody response by lipopolysaccharide.
