Abstract
Abstract There are disclosed polypeptides having the formula: R1-Lys-Lys-X-R2 wherein R1 is hydrogen or p-Glu; X is Glu or Asp; and R2 is Val, NH2 or Val-NH2; the fully protected peptide-resin intermediates thereof and pharmaceutically acceptable salts thereof. These polypeptides have the capability of inducing the maturation of T-cell populations and thus are useful in a number of therapeutic areas.
