Abstract:
This disclosure describes immunogens, compositions, and methods for treating dyslipidemia. The immunogen included an ApoC3-derived peptide linked to a bacteriophage virus like particle (VLP) immunogenic carrier. The ApoC3 immunogen can be administered to a subject having, or at risk of having, dyslipidemia. The ApoC3 immunogen may be administered alone or co-administered with an additional dyslipidemia therapeutic agent.
Abstract:
The present invention concerns a nucleic acid which is capable of regulating the transcription of the ABC1 gene, which is a causal gene for pathologies linked to a dysfunctioning of cholesterol metabolism, inducing diseases such as atherosclerosis. The invention also relates to nucleotide constructs comprising a polynucleotide which encodes a polypeptide or a nucleic acid of interest, placed under the control a regulatory nucleic acid for the ABC1 gene. The invention also relates to recombinant vectors, transformed host cells and nonhuman transgenic mammals comprising a nucleic acid which regulates the transcription of the ABC1 gene or an abovementioned nucleotide construct, as well as methods for screening molecules or substances which are capable of modifying the activity of the regulatory nucleic acid for the ABC1 gene.
Abstract:
The present invention provides an isolated mammalian receptor which specifically binds a high density lipoprotein holoparticle, comprising a subunit of approximately 45-600 kDa molecular weight and one or more subunits selected from the group consisting of a subunit of approximately 40-50 kDa molecular weight, a subunit of approximately 120 kDa molecular weight and a subunit of approximately 400 kDa molecular weight. In addition, the present invention provides a method of screening a substance for the ability to modulate the HDL holoparticle binding and/or internalization activity of the receptor of this invention, comprising: a) contacting the substance with a cell producing a functional HDL receptor; and b) assaying the cell for a modulation of the HDL holoparticle binding and/or internalization activity of the receptor, whereby a modulation of the HDL holoparticle binding and/or internalization activity of the receptor identifies a substance with the ability to modulate the HDL holoparticle binding and/or internalization activity of the ADL receptor.
Abstract:
An immunogen generally includes a virus-like particle and an antigen linked to the virus-like particle. The antigen includes an antigenic portion of a polypeptide, wherein the polypeptide inhibits lipoprotein lipase (LPL) activity by binding to LPL. In some embodiments, the polypeptide is at least a portion of angiopoietin-like 3 (ANGPTL3). In other embodiments, the polypeptide is at least a portion of angiopoietin-like 4 (ANGPTL4). In other embodiments, the polypeptide at least a portion of angiopoietin-like 8 (ANGPTL8). In some embodiments, the virus-like particle is a Qbeta immunogenic carrier. In some of these embodiments, the antigen is linked to the virus-like particle through a Gly-Gly-Gly-Cys linker at the C-terminal of the antigen.
