Pseudosecondary antibody response to LPS induced by toxins for macrophages
Abstract
A single dose of bacterial lipopolysaccharide, administered 21 days after mice had been treated with the macrophage toxins carrageenan, or microparticulate crystalline silica, resulted in a secondarytype antibody response. The phenomenon of pseudosecondary responsiveness was investigated to determine the mechanism for its generation. The results showed that generating a pseudosecondary response was T cell dependent; but except for this, it followed the same kinetic and genetic patterns as a true, two dose of antigens, secondary response. It was concluded that pseudosecondary responsiveness resulted from priming the mice by the consequential effects of the macrophage toxins; thereafter, secondary responsiveness to LPS was generated in a normal manner.
