<p>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 IIβ 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 compositions useful as a pharmaceutical, adjuvant, immunostimulant or immunomodulator to activate the immune system wherein the compositions may also be peptides, non-peptide mimetics or organic molecules selected from aliphatics, carbohydrates, heterocyclics, aromatics or mixtures thereof.</p> |
