Adjuvanticity (immunity-inducing property) of cord factor in mice and rats

Abstract

Cord factor, a glycolipid in mycobacteria, was found to make a tolerogenic protein antigen immunogenic when injected 0 to 2 days before tolerogen injection in mice and rats. Cord factor was also found to increase phagocytic function of the reticuloendothelial system of mice, and the relationship between the immunity-inducing capacity and the phagocytic function is discussed.
