  • Patent number: 11124551
    Abstract: Described herein is a novel, mitochondrial encoded, open reading frame, that leads to the production of a new mitochondrial peptide. Residing within the ND-Two subunit, a specific small nucleotide polymorphism disrupts expression of this mitochondrial peptide, and is correlated with an increase in obesity and diabetes, particularly in certain ethnic populations. In vitro administration of the peptide increases insulin secretion, decreases fat accumulation and improves glucose uptake in muscle cell. Antibodies generated against the peptide can be used for detecting peptide deficiency, in addition to SNP detection, supporting diagnostic approaches. In vivo studies further revealed that administration of the peptide improves glucose tolerance, thereby providing a new therapeutic avenue for a novel diabetes therapy and decreases bodyweight, thus serving as a novel obesity therapy. Generation of synthetic analogs further enhance or abrogated activity relative to the natural peptide.

  • Patent number: 9453217
    Abstract: Antigen-specific immunoglobulin V-regions are identified from a library of nucleic acids amplified using polymerase chain reaction using leader sequence-specific forward primers. The use of leader sequence primers allows all V-region sequences to be amplified (including those with extensive 5? end mutations) without loss of the original 5? V gene segment sequence. These libraries can be screened for antigen-specific V-regions using eukaryotic cells engineered to express the amplified V-region-encoding nucleic acids or using bacterial phage display techniques. In the latter, a second V-region library is made using a larger than conventional set of 5? V-region primers. The sequence errors introduced into the amplification products by this method are corrected using sequence information obtained in the products amplified by the V-region primers to screen the library created using the leader sequence primers.

    Abstract: The present invention relates to humanisation of antibodies in vivo. The invention provides non-human vertebrates, cells, populations and methods useful for humanising chimaeric antibodies in vivo. Using the present invention it is possible straightforwardly and rapidly to obtain antigen-specific antibodies that are fully human (ie, comprising human variable and constant regions) and have undergone recombination, junctional diversification, affinity maturation and isotype switching in vivo in a non-human vertebrate system. Furthermore, such antibodies are humanised (eg, totally human)—and selected—totally in vivo, and as such the present invention harnesses in vivo filtering for expressibility, affinity and biophysical characteristics in the context of the desired human variable and constant region pairings. This is avoids problems of down-grading antibody characteristics when humanising the constant region of chimaeric antibodies in vitro.

  • Publication number: 20150031583
    Abstract: A phage display system is provided comprising a mutant phage-infected host cell adapted to express a peptide of interest fused to a phage capsid protein, wherein the mutant phage includes a nonsense mutation which prevents expression of the capsid protein as a functional protein, and wherein expression of the peptide of interest is controlled by an inducible repressor and by a suppressor that suppresses the nonsense mutation.

  • Publication number: 20150018236
    Abstract: Methods for screening libraries of polypeptides for biologically activity on cells. For example, polypeptides can be synthesized and encapsulated along with their coding sequences in microcapsules of an emulsion. Emulsion microcapsules can then be fused with microcapsules comprising test cells and biological activity on the cells is assessed to identify biologically active polypeptides and nucleic acid molecules encoding the same.
