The invention is related to peptide constructs, i.e., polypeptides obtained by linking together two or more peptides based on or derived from different molecules, which are useful in the treatment or prevention of cancer or the treatment of autoimmune diseases and compositions containing same, methods for producing same, and methods for using same; wherein the peptide constructs have the formula P-x-Pwhere Pis a peptide associated with forms of cancer or an autoimmune condition and Pis a peptide which will bind to a class of immune cells such as dendritic cells. The peptide construct can cause the maturation of immature dendritic cells to a more mature state. The peptide construct or the more mature dendritic cells can be administered to a subject to a modulate or to initiate an immune response against cancer cells, and can be used with dyes, radioisotopes, or therapeutic agents for detection of the immune target and/or treatment of cancer and autoimmune conditions.

Method for inducing an immune response for treatment of cancer and autoimmune diseases or conditions

Peptide constructs chemically synthesized to contain a Herpes Simplex Virus specific antigenic peptide, such as, the 322-332 peptide (H1) from the ICP27 protein of Herpes Simplex Virus (HSV-1) and a peptide from a T cell binding ligand (TCBL), such as &bgr;-2M (aa 35-50), which elicits a TH1-like response in vitro tests in mice, were protective against challenge with HSV.
