The invention provides antibodies that specifically bind human α-synuclein with a high affinity and reduces α-synuclein spreading in vivo, recombinant polypeptides comprising said antibodies or antigen-binding fragment thereof and methods for generating such polypeptides, as well as compositions and methods for generating α-synuclein antibodies, and methods of using α-synuclein antibodies for the treatment of diseases of the central nervous system, in particular alpha-synucleinopathies.

Provided herein are chimeric antigen receptors (CARs) for cancer therapy, and more particularly, CARs containing a scFv from a CD33 monoclonal antibody. Provided are immune effector cells containing such CARs, and methods of treating proliferative disorders such as acute myeloid leukemia (AML), and relapsed or refractory AML.

The present invention describes antibodies that target CD19, wherein the antibodies comprise at least one modification relative to a parent antibody, wherein the modification alters affinity to an FcγR or alters effector function as compared to the parent antibody. Also disclosed are methods of using the antibodies of the invention.

This disclosure relates to the use of anti-α-synuclein antibody to diagnose an elevated level of α-synuclein in the brain. Specifically, the disclosure relates to the method of assessing the levels of α-synuclein in a blood plasma or CSF following administration to the test subject of an anti-α-synuclein antibody or antigen-binding fragment thereof, which can bind α-synuclein with sufficient activity to alter the net efflux of α-synuclein from brain to blood, or from brain to CSF.

Improved anti-CD154 antibodies are provided herein which have ablated FcR binding and/or complement binding/activation. The use of these antibodies for inducing tolerance and treating immune diseases including autoimmunity, inflammation and allergic disorders is disclosed herein.

The present invention relates to Chimeric Antigen Receptors (CAR) that are recombinant chimeric proteins able to redirect immune cell specificity and reactivity toward CLL1 positive cells. The engineered immune cells endowed with such CARs are particularly suited for immunotherapy for treating cancer, in particular leukemia.

The disclosure provides antibodies that are useful for, among other things, inhibiting terminal complement (e.g., the assembly and/or activity of the C5b-9 TCC) and C5a anaphylatoxin-mediated inflammation and, thus, treating complement-associated disorders. The antibodies have a number of improved properties relative to eculizumab, including, e.g., increased serum half-life in a human.

The invention provides anti-CLL-1 antibodies and immunoconjugates and methods of using the same.

The invention provides compositions and methods for effective lysosomal targeting mediated by PCSK9. In particular, the compositions and methods provided by the invention may be used to treat lysosomal storage diseases such as Pompe Disease and Sanfilippo Syndrome Type B, and they may be used for targeting lysosomal enzymes to the various muscles of the human body.

The present invention relates to antibody molecules and peptide delivery systems for use in the treatment and management of Alzheimer's disease and related disorders. In particular, the antibody molecules preferentially bind oligomeric forms of beta-amyloid peptide, in single domain format, and the peptide delivery systems facilitate specific transport of such antibody molecules, as well as other cargo molecules, across the blood-brain barrier. The invention also relates to constructs of the antibody molecules and the delivery peptides, as well as pharmaceutical compositions comprising effective amounts of the antibody molecules, delivery peptides, and/or their constructs, including humanized versions of the antibody molecules and constructs. The invention further relates to methods of making these products and pharmaceutical compositions thereof; and methods of using the pharmaceutical compositions in treating or preventing Alzheimer's and related disorders, such as those involving accumulation of beta-amyloid peptide or other peptides that aggregate in the brain; as well as to methods and kits for diagnosing these disorders.
