The present invention relates to methods of using biologically active Fc domain-containing therapeutic constructs (Fc constructs) to induce immune cell activation of the immune response in a subject, and for example, to treat diseases such as cancers and infections in a subject. Such Fc constructs may include 5 or more Fc domains.

Methods related to engineered Fc constructs

The invention encompasses the discovery that Fc-containing polypeptides that include branched glycans and that are sialylated on the branched glycan (e.g., on an α 1,3 and/or α 1,6 arm in the Fc region's N-linked glycosylation site), with, e.g., a NeuAc-α 2,6-Gal or NeuAc-α 2,3-Gal terminal linkage, are useful in treating neurodegeneration, e.g., in the treatment of neurodegenerative diseases such as Alzheimer's Disease. The present disclosure provides, in part, methods for treating neurodegeneration or neurodegenerative diseases by administering compositions containing such Fc-containing polypeptides as well as methods for evaluating, identifying, and/or producing (e.g., manufacturing) such polypeptides for the treatment of neurodegeneration.

Methods for the treatment of neurodegeneration

Described herein are methods for treating rheumatoid arthritis by determining whether a subject having rheumatoid arthritis will respond to an anti-TNF-alpha therapy based on the number of innate and adaptive immune cells in a sample from the subject prior to treatment.

Methods for predicting response to treatment

The present invention relates to compositions and methods of engineered IgG Fc constructs, wherein said Fc constructs include one or more Fc domains.

Compositions and methods related to engineered Fc constructs

The present invention features antibodies that bind to human neonatal Fc receptor (FcRn). These anti-FcRn antibodies are useful, e.g., to promote clearance of autoantibodies in a subject, to suppress antigen presentation in a subject, to block an immune response, e.g., block an immune complex-based activation of the immune response in a subject, and to treat immunological diseases (e.g., autoimmune diseases) in a subject. These anti-FcRn antibodies are also useful, e.g., to decrease pathogenic antibody transport across the placenta of a pregnant subject, to increase pathogenic antibody catabolism in a pregnant subject, and to treat an antibody-mediated enhancement of viral disease in a fetus or a neonate.

FcRn antibodies and methods of use thereof

The present invention features antibodies that have high binding affinity to human neonatal Fc receptor (FcRn). These anti-FcRn antibodies are useful, e.g., to promote clearance of autoantibodies in a subject, to suppress antigen presentation in a subject, to block an immune response, e.g., block an immune complex-based activation of the immune response in a subject, and to treat immunological diseases (e.g., autoimmune diseases) in a subject.

Pharmaceutical preparations containing polypeptides having particular sialylation patterns, and methods for the treatment of immune-related thrombocytopenia with such preparations, are described.

Sialylated glycoproteins

The invention encompasses the discovery that Fc-containing polypeptides that include branched glycans and that are sialylated on the branched glycan (e.g., on an &#x3b1; 1,3 and/or &#x3b1; 1,6 arm in the Fc region's N-linked glycosylation site), with, e.g., a NeuA-&#x3b1; 2,6-Gal or NeuAc-&#x3b1; 2,3-Gal terminal linkage, are useful in treating neurodegeneration, e.g., in the treatment of neurodegenerative diseases such as Alzheimer's Disease. The present disclosure provides, in pert, methods for treating neurodegeneration or neurodegenerative diseases by administering compositions containing such Fc-containing polypeptides as well as methods for evaluating, identifying, and/or producing (e.g., manufacturing) such polypeptides for the treatment of neurodegeneration.
