Super humanized antibodies

Disclosed herein are methods for humanizing antibodies based on selecting variable region framework sequences from human antibody genes by comparing canonical CDR structure types for CDR sequences of the variable region of a non-human antibody to canonical CDR structure types for corresponding CDRs from a library of human antibody sequences, preferably germline antibody gene segments. Human antibody variable regions having similar canonical CDR structure types to the non-human CDRs form a subset of member human antibody sequences from which to select human framework sequences. The subset members may be further ranked by amino acid similarity between the human and the non-human CDR sequences. Top ranking human sequences are selected to provide the framework sequences for constructing a chimeric antibody that functionally replaces human CDR sequences with the non-human CDR counterparts using the selected subset member human frameworks, thereby providing a humanized antibody of high affinity and low immunogenicity without need for comparing framework sequences between the non-human and human antibodies. Chimeric antibodies made according to the method are also disclosed.

Multipurpose antibody derivatives

The present invention relates to a class of molecules specified as novel multipurpose antibody derivatives. This class of molecules is created by heterodimerization of two constituting components. Heterodimerization is obtained by the specific heterotypic interaction of a chosen VH-CH1 combination of immunoglobulin domains, with a chosen VL-CL combination of immunoglobulin domains. The appropriate VH and VL domains in the VHCH1 and VLCL context, a binding specificity can be constitituted by the heterodimerization scaffold itself. One or both of the comprising VHCH1 and VLCL chains can thus be extended at either the N- or the C-terminus or both with other molecules, such as a toxin polypeptide, an enzyme, a hormone, a cytokine, a signaling molecule, or a single chain linked Fv fragment with the same or a different specificity.

Prosthetic heart valves, support structures and systems and methods for implanting same

Described herein are systems and methods for operation of a prosthetic valve support structure (32) having additional reinforcement coupled with panels (36). Multiple support members (620) are distributed across the inner surface of the valve support structure (32) at regular intervals. Each support member (620) can include a looped portion (621) to act as a hinge (52). Each looped portion (621) is in a location coincidental with the interlace between adjacent panels (36).

Recombinant binding proteins and peptides

DNA constructs comprise a first exon sequence of nucleotides encoding a first peptide or polypeptide, a second exon sequence of nucleotides encoding a second peptide or polypeptide and a third sequence of nucleotides between the first and second sequences encoding a heterologous intron, for example that of Tetrahymena thermophila nuclear pre-rRNA, between RNA splice sites and a site-specific recombination sequence, such as loxP, within the intron, the exons together encoding a product peptide or polypeptide. Such constructs are of use in methods of production of peptides or polypeptides, transcription leading to splicing out of the intron enabling translation of a single chain product peptide or polypeptide. Isolated nucleic acid constructs consisting essentially of a sequence of nucleotides encoding a self-splicing intron with a site-specific recombination sequence within the intron, for use in creation of constructs for expression of peptides or polypeptides, are also provided.

Bivalent IgY antibody constructs for diagnostic and therapeutic applications

This invention relates to the field of recombinant antibody technology. It provides novel recombinant IgY antibody constructs for diagnostic and therapeutical applications. The bivalent antibody constructs display a heterotetrameric or homodimeric format stabilized by disulfide bonds. The constant heavy chain domains CH2-CH4 are partly or completely of avian origin, whereas the VH, VL, CL, and CH1 domains as well as the hinge region may be of avian origin or derived from any other species. The invention allows to combine the advantages of IgY antibodies with those of established mammalian monoclonal antibodies. IgY antibody constructs comprising nonglycosylated IgY constant heavy chain domains allow to reduce unwanted interactions with C-type lectins, e.g., in human sera. Furthermore, chimeric IgY antibody containing mammalian VH, VL, CL, and CH1 domains as well as a mammalian hinge region provide a higher molecular stability than IgY antibodies in acidic conditions and, thereby, are especially suited for peroral therapeutic applications.

Antibodies specific for sclerostin and methods for increasing bone mineralization

Compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.

Rationally Designed, Synthetic Antibody Libraries and Uses Therefor

The present invention overcomes the inadequacies inherent in the known methods for generating libraries of antibody-encoding polynucleotides by specifically designing the libraries with directed sequence and length diversity. The libraries are designed to reflect the preimmune repertoire naturally created by the human immune system and are based on rational design informed by examination of publicly available databases of human antibody sequences.
