Disclosed are yeast cells expressing a polypeptide comprising a signal sequence and a human ApoE protein. In some embodiments the polypeptide comprises ApoE2. In some embodiments the polypeptide comprises ApoE3. In some embodiments the polypeptide comprises ApoE4. Also disclosed are methods of screening yeast cells to identify compounds that prevent or suppress Apo-induced toxicity. Compounds identified by such screens can be used to treat or prevent neurodegenerative disorders such as Alzheimer's disease. Also disclosed are methods of screening yeast cells to identify genetic suppressors or enhancers of ApoE-induced toxicity. Also disclosed are genetic suppressors or enhancers of ApoE-induced toxicity identified using the methods, and human homologs thereof. Also disclosed are methods of identifying compounds that modulate expression or activity of genetic modifiers of ApoE-induced toxicity.

The present disclosure provides methods, uses and compositions and kits for use in inducing an antibody immune response in a human subject. The methods and uses involve administering parenterally a low dose volume of a composition comprising an antigen comprising a B-cell epitope, an amphipathic compound, and a hydrophobic carrier, wherein the low dose volume of the composition is less than 100 μl and induces an antibody immune response to the B-cell epitope in the human subject.

Provided is a platform for expressing a protein of interest by artificially manipulating the liver, and more particularly, to a platform for alleviating or treating a genetic disorder or improving a body function by inducing expression by inserting a transgene (e.g., a therapeutic gene) which can function or be expressed normally, into a high-expression secretory gene, instead of a disease gene which functions or is expressed abnormally. The high-expression secretory gene includes the HP or APOC3 gene. The transgene includes one that is highly expressed using a promoter in a hepatocyte genome and is secretory out of the cell.

In various embodiments, methods of concentrating apolipoprotein A-I mimetic peptide activity in transgenic plant material expressing such peptides are provided. In certain embodiments the methods involve providing a tissue of a transgenic plant where the tissue contains a heterologous ApoA-I mimetic peptide expressed by the plant, and where the tissue is provided as a substantially dry powder; mixing the powder with a solution comprising ethyl acetate and acetic acid or with a solution comprising ethyl lactate and lactic acid, to form an extraction mixture; and collecting the liquid phase of said mixture and drying said liquid phase to provide a concentrated dry powder extract that displays the biological activity of the apoA-I mimetic peptide.

A seed-specific expression vector and its construction methods and applications are disclosed. A fusion protein expression cassette consisting of Arachis hypogaea oleosin gene-apolipopoprotein A-I.sub.Milano (A-IM) gene driven by Brassica napus oleosin gene promoter is inserted between the HindIII and SacI sites of a plant binary expression vector pBI121, obtaining the plant expression vector pBINOA of the invention. In addition, a method for producing apolipoprotein A-I.sub.Milano is provided, in which the expression vector is used to transform oil sunflower which is used as a plant bioreactor. The method can not only improve the yield of apolipoprotein A-I.sub.Milano, but also greatly reduce production costs, and is suitable for industrial production.
