Abstract

Abstract There are disclosed polypeptide compositions having the following amino acid sequence as the active site: ARG-LYS-ASP-VAL-TYR These polypeptides have the capability of inducing the differentiation of T-lymphocytes but not of complement receptor (CR+) B-lymphocytes and thus are useful in a number of therapeutic areas. Also provided are derivatives of the pentapeptide, novel intermediate polypeptides, methods of manufacture of the peptides, therapeutic compositions, and methods for use of the compositions.
