  • Publication number: 20210030799
    Abstract: A Tumor Micro-Environment (TME) responsive expression vector including a nucleic acid sequence encoding a synthetic promoter comprising one or more promoter-response-elements, and a nucleic acid sequence encoding immune-effector genes, such as chimeric antigen receptor. The TME responsive vector is designed to induce the expression of immune-effector genes within TME, and not in normal healthy tissues, thus focusing immune activities, increasing safety and reducing the ON-target OFF-tumor hazard.

  • Publication number: 20140120126
    Abstract: The present invention provides improved vaccines comprising an isolated viral antigenic peptide and a synthetic peptide derived from a T cell epitope of HSP60. The invention includes mixtures where the peptide serves as an adjuvant as well as conjugates where the peptide is covalently linked to the viral antigen. The known synthetic peptide carrier, p458, provides significantly improved immunogenicity for synthetic viral epitopes and analogs. Ec27 is a novel peptide derived from HSP60 which increases the immunogenicity substantially of the viral antigen both as a mixture or a covalent conjugate. Some of the isolated viral epitopes are novel and are claimed for diagnostic as well as therapeutic or prophylactic uses.
