Abstract: The present invention describes compositions and methods for targeting complement inhibition to sites of p-selectin expression, and compositions for inhibiting p-selectin and complement.

Abstract: The present invention provides therapeutics for the treatment of CD22-positive cancers such as B-cell acute lymphoblastic leukemia (B-ALL). In particular, the present invention provides an anti-CD22 monoclonal antibody whose scFv as a part of chimeric antigen receptors (CAR) T-cells can target the first Ig extracellular domain of the CD22 antigen, the farthest domain from the membrane, for use in the treatment of CD22-positive cancers.

Abstract: Provided herein, inter alia, are compositions and methods of using the same for detecting complement activation.

Abstract: The present invention describes compositions and methods for targeting complement inhibition to sites of p-selectin expression, and compositions for inhibiting p-selectin and complement.

Abstract: Disclosed are methods of treating subjects having cancers including administering an effective amount of an early activation molecule agonist, antagonist or depletor, to the subject. Human monoclonal antibodies specific to the early activation molecules, and methods of use, are also disclosed.

Abstract: The present invention is concerned with a series of novel monoclonal antibodies directed against CD22, a B lineage-restricted member of the Ig-superfamily which serves as an adhesion receptor expressed by mature B lymphocytes and is believed to function in the regulation of B cell activation. The monoclonal antibodies (mAb) specifically block red blood cell and leukocyte adhesion (80-100%) to COS cells transfected with CD22 cDNA and also identify a region of CD22 distinct from those defined by previously described CD22 mAb. The invention also encompasses therapeutic compositions including therapeutically effective amounts of a polypeptide comprising the CD22 ligand or portion thereof or of a polypeptide comprising the first two amino terminal Ig-like domains of CD22, or the ligand binding portion thereof. The antibodies and polypeptides of the invention find use in therapeutic methods for treatment of humans to retard or block CD22 adhesive function, particularly in autoimmune disease.
