METHODS FOR TREATING DISEASES OR CONDITIONS WITH PEPTIDE CONSTRUCTS

摘要

This invention relates to peptides directing a CD4 related T helper cell response wherein the peptides may be used as an adjuvant provided with an antigen or as an immunomodulatory agent without an antigen and compositions comprising modification of a fifteen-mer peptide sequence from the MHC IIbeta chain at positions 135-149 known as Peptide G or a derivative of derG or other derivatives wherein the derivatives enhance the immune response of antigens and methods for treating cancer, autoimmune disease, transplant conditions, infectious conditions or allergies caused by foreign eukaryotic organisms, and infectious conditions or allergies caused by prokaryotic organisms or non­living agents such as viruses, phages and prions with polypeptides.
