The present disclosure provides (a) isolated immunogenic PAA polypeptides; (b) isolated nucleic acid molecules encoding immunogenic PAA polypeptides; (c) vaccine compositions comprising an immunogenic PAA polypeptide or an isolated nucleic acid molecule encoding an immunogenic PAA polypeptide; (d) methods relating to uses of the polypeptides, nucleic acid molecules, and compositions; and (e) vaccine-based immunotherapy regimens which involve co-administration of a vaccine in combination with an immune-suppressive-cell inhibitor and an immune-effector-cell enhancer.

Prostate-associated antigens and vaccine-based immunotherapy regimens

Molecular constructs and dual recognition constructs having a sequence encoding a TCR affinity weakening motif, and DNA and RNA sequences corresponding thereto, are presented. Modified T-cells and other cells transformed with the molecular contracts express a modified TCR that imparts a reduction, in non-specific binding, -an enhancement of binding specificity and an enhancement of binding affinity for a target antigen, compared to non-transformed (wild-type, native) T-cells, are described. The modified TCRs possess an affinity enhancing motif and an affinity weakening motif. Methods of transforming cells and methods of using enriched populations of transformed cells, in the treatment of cancer and infections arid T-cell mediated pathologies are provided. The affinity weakening motif imparts a weakened interaction, of a TCR with major histocompatibility complex proteins, such as HLA proteins in humans. Soluble modified TCRs are also provided, Therapeutic preparations comprising modified T-cells, modified TCRs, and modified TCR-therapeutic agent-conjugates, are also provided.

Molecular constructs and uses thereof

The present invention relates to the provision of novel immunogens comprising an antigenic PCSK9 peptide linked to an immunogenic carrier for the prevention, treatment or alleviation of PCSK9-mediated disorders. The invention further relates to methods for production of these medicaments, immunogenic compositions and pharmaceutical compositing thereof and their use in medicine.
