Chimeric peptides comprising HER-2 B-cell epitopes and T-helper epitopes

Compositions for stimulating the immune system and for treating malignancies associated with overexpression of the HER-2 protein are provided. Such compositions include immunogenic epitopes of the HER-2 proteins and chimeric and multivalent peptides which comprise such epitopes. The present invention also relates to polynucleotides which encode the chimeric peptides. Also provided are pharmaceutical compositions comprising such immunogenic compositions. Methods for stimulating an immune response to HER-2 protein are provided. Methods for treating breast cancer, ovarian cancer, prostate cancer, colon cancer and lung cancer are provided.

Polypeptides and polynucleotides for enhancing immune reactivity to HER-2 protein

Compositions for and methods of treating patients with malignancies associated with overexpression of VEGF, particularly ovarian cancer are provided herein. The compositions include but are not limited to certain VEGF epitopes, multivalent peptides comprising the epitopes, and chimeric peptides comprising one or more of the epitopes and a T cell epitope.

The present invention provides synthetic chimeric fimbrin peptides which induce an immunogenic response in animals to non-typable Haemophilus influenzae and that do not require tedious purification techniques. The synthetic chimeric fimbrin peptides reduce the severity of otitis media caused by Haemophilus influenzae. The synthetic chimeric fimbrin peptides are synthesized using commercially available peptide synthesizers. The synthetic chimeric fimbrin peptides comprises three peptide units. The first peptide unit is a subunit of the fimbrin protein. Preferably, the fimbrin subunit is comprised of the amino acids of Sequence ID No. 1 or Sequence ID No. 2. The second peptide unit is a t cell epitope, and preferably has the amino acid sequence of SEQ ID NO. 3. The third peptide unit is a linker peptide unit which joins the first and second peptide unit. The linking sequence preferably has from about 2 to about 15 amino acids, more preferably from about 2 to about 10 amino acids, most preferably from about 5 to about 6 amino acids. The synthetic chimeric fimbrin peptides are useful immunognes against NTHi and also useful as laboratory tool for detecting antibodies in sera. The invention also relates to an immunogenic composition conmtaining the synthetic chimeric fimbrin peptides and a pharmacologically acceptable carrier.
