The invention concerns a fusion polypeptide comprising a plurality of conserved peptide sequences, or variants thereof, wherein at least one of the conserved sequences is conserved across: i) HCV genotypes 1a and 1b; ii) HCV genotypes 1 and 3; or iii) HCV genotypes 1 to 6; and wherein at least one of the conserved peptide sequences comprises at least part of a sequence of a non-structural protein of the HCV genotypes; including associated nucleic acid and vector sequences, and use in methods of treatment or prophylaxis, such as vaccination.

Provided herein are compositions and methods for inducing protein function. For example, in some embodiments, provided herein are compositions and methods for pharmacological induction of protein function.

The present disclosure provides an immunogenic composition comprising: a) i) a hepatitis C virus (HCV) heterodimeric polypeptide that includes HCV E1 and E2 polypeptides; ii) an HCV E1 polypeptide; or iii) an HCV E2 polypeptide; b) a polypeptide (also referred to herein as a T-cell epitope polypeptide or an HCV T-cell epitope polypeptide) comprising T-cell epitopes (e.g., CD4+ and CD8+ T-cell epitopes that are conserved among some HCV genotypes and that are presented through one or multiple HLA alleles common within the human population) present in an HCV protein other than E1 and E2; and c) a pharmaceutically acceptable excipient. The present disclosure provides a method of inducing an immune response, in an individual, to an HCV polypeptide.

Provided is a recombinant vector including a porcine Fc fragment. By fusing the porcine Fc fragment with various target proteins by using the recombinant vector of the present invention, not only target proteins may be expressed using various hosts including plants, but the productivity and stability of target proteins may also be increased.

The technology described herein is directed to CAR polypeptides and systems comprising repressible proteases. In combination with a specific protease inhibitor, the activity of said CAR polypeptides and systems and cells comprising them can be modulated. Also described herein are methods of using said CAR polypeptides and systems, for example to treat various diseases and disorders.

The present invention provides novel engineered HCV E2 polypeptide immunogens and related vaccine compositions that display the engineered E2 polypeptides. The invention also provides methods of using such immunogens and vaccine compositions in various therapeutic applications, e.g., for preventing or treating HCV infections.

The present invention relates to novel therapeutic approaches for treating or preventing diseases in mammals, particularly in human subjects, using a PLA2-GIB cofactor, or a modulator of a PLA2-GIB cofactor.

The present invention relates to novel therapeutic approaches for treating cancer in mammals, particularly in human subjects, using an inhibitor of a PLA2-GIB cofactor.

The present invention provides a composition comprising hepatitis B virus (HBV) component(s), and which may be either nucleic acid- or polypeptide-based as well as nucleic acid molecules and vectors encoding such HBV component(s). It also relates to infectious viral particles and host cells comprising such nucleic acid molecules or vectors. It also provides composition and kits of parts comprising such nucleic acid molecules, vectors, infectious viral particles or host cells and the therapeutic use thereof for preventing or treating HBV infections.

Provided is an antigen fused with a porcine Fc fragment, a vaccine composition having a self-adjuvanting effect by binding an Fc fragment to various antigens, and a method of producing the antigen.
