Glycosylation engineering of antibodies for improving antibody-dependent cellular cytotoxicity

InactiveUS6602684B1Increase healing valueEnhanced Fc-mediated cellular cytotoxicityNanotechFungiAntibody fragmentsADAMTS Proteins
The present invention relates to the field glycosylation engineering of proteins. More particular, the present invention is directed to the glycosylation engineering of proteins to provide proteins with improved therapeutic properties, e.g., antibodies, antibody fragments, or a fusion protein that includes a region equivalent to the Fc region of an immunoglobulin, with enhanced Fc-mediated cellular cytotoxicity.

Use of chimeric nucleases to stimulate gene targeting

Gene targeting is a technique to introduce genetic change into one or more specific locations in the genome of a cell. For example, gene targeting can introduce genetic change by modifying, repairing, attenuating or inactivating a target gene or other chromosomal DNA. In one aspect, this disclosure relates to methods and compositions for gene targeting with high efficiency in a cell. This disclosure also relates to methods of treating or preventing a genetic disease in an individual in need thereof. Further disclosed are chimeric nucleases and vectors encoding chimeric nucleases.

Use of Chimeric Antigen Receptor-Modified T-Cells to Treat Cancer

The present invention provides compositions and methods for treating cancer in a human. The invention includes relates to administering a genetically modified T cell to express a CAR wherein the CAR comprises an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain.

Method for making multispecific antibodies having heteromultimeric and common components

The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins and antibody-immunoadhesin chimeras. The invention also relates to the heteromultimers prepared using the method. Generally, the method provides a multispecific antibody having a common light chain associated with each heteromeric polypeptide having an antibody binding domain. Additionally the method futher involves introducing into the multispecific antibody a specific and complementary interaction at the interface of a first polypeptide and the interface of a second polypeptide, so as to promote heteromultimer formation and hinder homomultimer formation; and / or a free thiol-containing residue at the interface of a first polypeptide and a corresponding free thiol-containing residue in the interface of a second polypeptide, such that a non-naturally occurring disulfide bond is formed between the first and second polypeptide. The method allows for the enhanced formation of the desired heteromultimer relative to undesired heteromultimers and homomultimers.

Nucleic acid encoding poly-zinc finger proteins with improved linkers

Polynucleotides encoding chimeric proteins, and methods for their production and use are disclosed. The chimeric proteins comprise a flexible linker between two zinc finger DNA-binding domains, wherein the linker contains eight or more amino acids between the second conserved histidine residue of the carboxy-terminal zinc finger of the first domain and the first conserved cysteine residue of the amino-terminal zinc finger of the second domain.

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.

Methods and compositions for targeted cleavage and recombination

Disclosed herein are methods and compositions for targeted cleavage of a genomic sequence, targeted alteration of a genomic sequence, and targeted recombination between a genomic region and an exogenous polynucleotide homologous to the genomic region. The compositions include fusion proteins comprising a cleavage domain (or cleavage half-domain) and an engineered zinc finger domain and polynucleotides encoding same. Methods for targeted cleavage include introduction of such fusion proteins, or polynucleotides encoding same, into a cell. Methods for targeted recombination additionally include introduction of an exogenous polynucleotide homologous to a genomic region into cells comprising the disclosed fusion proteins.
