The compositions and methods are described for generating an immune response to a tumor associated antigen (TAA) such as MUC-1, survivin, cyclin B1, HBV, or HPV. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to the tumor associated antigen in the subject to which the vector is administered and optionally, boosting the immune response by administering a tumor associated antigen. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat neoplasms and associated diseases.

The present disclosure provides a DNA vaccine for a subject having a human papillomavirus (HPV)-associated disease. The DNA vaccine may include a DNA construct including a fusion gene. The fusion gene may be a subsegment of the DNA construct that includes an optimized HPV subsequence encoding at least one HPV antigen. The optimized HPV subsequence may include one or more of: an HPV-16 E6 expressing gene set forth in SEQ ID NO: 1, an HPV-16 E7 expressing gene set forth in SEQ ID NO: 2, an HPV-18 E6 expressing gene set forth in SEQ ID NO: 3, and an HPV-18 E7 expressing gene set forth in SEQ ID NO: 4.

Provided herein are binding proteins recognizing HPV16 E7 antigen and uses thereof.

The invention relates to a nucleic acid encoding a polypeptide comprising a plurality of conserved peptide sequences, or variants thereof, wherein the conserved sequences are conserved across one or more HPV genotypes 16, 18, 31, 52, 53, and 58; and wherein the polypeptide comprises a conserved peptide sequence of each of the HPV proteins E1, E2, E4, E5, E6, and E7; and associated vaccines, viral vectors, treatment and prophylaxis.

A composition includes a contraceptive chimeric virus-like particle with an antigenic carrier domain and one or more antigenic regions from a sperm cell in the antigenic carrier domain, with the antigenic carrier domain including human papillomavirus L1 capsid protein and the antigenic regions including one or more structural elements of the Catsper ion channel complex. When administered to a patient, the contraceptive vaccine stimulates production of anti-sperm antibodies that, upon binding to a sperm cell, inhibit the sperm cell's motility and thus inhibit the ability of the sperm cell to fertilize an egg cell. The induced immunoinfertility of the composition can be reversed for brief or extended lengths of time by overdosing the patient with a reversal agent lacking the antigenic carrier domain but having a protein sequence substantially identical to that of the one or more antigenic regions to sequester the anti-sperm antibodies.

The present invention relates to novel CD4+ and CD8+ T cell epitopes that are specific for HPV-specific E6 and E7 oncoproteins, to peptides comprising these novel T cell epitopes, and to (vaccine) compositions comprising these peptides for use in methods for the prevention and/or treatment of HPV related diseases. Preferred epitopes are recognized by a T cell that infiltrates a cervical neoplastic lesion or by a T cell from a draining lymph node, and are presented by an HLA-DQ or HLA-DP molecule, or an HLA-B.

Disclosed are virus-inspired compositions and preparation methods thereof, where the compositions comprise mutant papillomavirus L1 proteins that spontaneously form capsid backbones and that are conjugated to a peptide comprising an epitope to form immune redirector capsids (IRCs). The epitopes on the peptides are designed to be recognized by a subject's immune system based on the subject's preexisting immune memory developed from the subject's past exposure to the epitope through infection or vaccination. The mutant papillomavirus L1 proteins possess three mutations including an amino-terminal truncation, a carboxy-terminal truncation, and a truncation at helix four. These mutations in the L1 protein yield capsomeres that are form non-canonical T=1 geometry capsid backbones. Disclosed are uses and methods of using the compositions in treating and/or preventing cancers in subjects in need thereof.

Embodiments relate to novel vaccines against human papillomavirus (HPV) and HPV-related diseases, including multiple types of cancers. The HPV vaccines are composed of anti-human dendritic cell (DC) surface receptor antibodies, including CD40, and E6/7 proteins of HPV16 and 18. The technology described is not limited to making vaccines against HPV16- and HPV18-related diseases and can be applied to making vaccines carrying E6/7 from any type of HPV. The HPV vaccines described can target DCs, major and professional antigen presenting cells (APCs), and can induce and activate potent HPV E6/7-specific and strong CD4+ and CD8+ T cell responses. The HPV vaccines can be used for the prevention of HPV infection and HPV-related diseases as well as for the treatment of HPV-related diseases, including cancers.

The present disclosure provides rAAV vectors and rAAV virions that specifically express exogenous nucleic acid sequences in CD14.sup.+ cells. The rAAV vectors or virions are useful for specifically expressing exogenous nucleic acid sequences encoding, for example, cancer antigens, viral antigens, and/or bacterial antigens in monocytes and dendritic cells. The rAAV transduced CD14.sup.+ cells can be used as antigen presenting cells that induce antigen-specific T cell responses. The present disclosure further provides methods producing rAAV virions and methods of immunotherapy.
