摘要： A fusion protein that is expressed in a recombinant protein body-like assembly (RPBLA) in host eukaryotic cells and organisms is disclosed. More particularly, a biologically active polypeptide fused to a protein sequence that mediates the induction of RPBLA formation is expressed and accumulated in host cells after transformation with an appropriate vector. The eukaryotic host cell does not produce protein bodies in the absence of the fusion protein. Methods for preparing and using the RPBLAs and the fusion protein are also disclosed, as are nucleic acid molecules that encode the fusion proteins.

摘要： Polypeptide sequences for inducing recombinant protein bodies are described. The sequences comprise a polyproline II (PPII) structure between two cysteine residues on either end and an ER signal sequence Recombinant protein bodies are useful for protein production because they allow for simple and efficient purification of high quantities of recombinant protein.In addition, other methods of using recombinant protein bodies, for example, in vaccination, are also described.

摘要： A method for forming a fusion protein that is expressed as a recombinant protein body-like assembly in host eukaryotic cells and organisms other than higher plants as host systems is disclosed. More particularly, peptides and proteins are fused to protein sequences that mediate the induction of recombinant protein body-like assembly (RPBLA) formation, are stably expressed and accumulated in these host cells after transformation with an appropriate vector. Methods for preparing the fusion protein are also disclosed.

摘要： An immunogen-specific is adjuvant for a vaccine or inoculum is disclosed. The adjuvant is comprised of particulate recombinant protein body-like assemblies (RPBLAs) that contain a recombinant fusion protein that contains two portions peptide-linked together. A first portion is a protein body-inducing sequence (PBIS) and a second portion is a T-cell stimulating immunogenic polypeptide whose sequence is that of a pathogenic polypeptide sequence present in or induced by a vaccine or inoculum. The adjuvant, when used as an inoculum in a host animal without a prior priming vaccination or inoculation, does not induce production of antibodies or T cell activation to the pathogenic sequence.

摘要： A method for purifying a recombinant fusion protein that is expressed as recombinant protein body-like assemblies (RPBLAs) in host cells is disclosed in which an aqueous homogenate of transformed host cells that express a fusion protein as RPBLAs having a predetermined density is provided. Regions of different density are formed in the homogenate to provide a region that contains a relatively enhanced concentration of the RPBLAs and a region that contains a relatively depleted concentration of the RPBLAs. The RPBLAs-depleted region is separated from the region of relatively enhanced concentration of RPBLAs, thereby purifying said fusion protein. The region of relatively enhanced concentration of RPBLAs can thereafter be collected as desired.
