Abstract:
Disclosed herein are isolated human monoclonal antibodies that specifically bind human CD22 with a dissociation constant (Kd) of 25 nM or less. Nucleic acids encoding these antibodies, expression vectors including these nucleic acid molecules, and isolated host cells that express the nucleic acid molecules are also disclosed. The antibodies can be used to detect human CD22 in a sample. In some cases, CD22 is soluble CD22. Methods of diagnosing a B-cell malignancy, or confirming a B-cell malignancy diagnosis, are disclosed herein that utilize these antibodies. Methods of treating a subject with a B-cell malignancy are also disclosed.
Abstract:
The present invention relates to functional binding fragments comprising the minimal binding fragments of VAR2CSA, to antibodies against such binding fragments of VAR2CSA, nucleic acids encoding such fragments of VAR2CSA as well as methods for their production. The invention further relates to conjugates and fusion proteins of VAR2CSA polypeptides including the minimal binding fragments and their use, in particular in the treatment of conditions associated with expression of chondroitin sulfate A (CSA), such as an inappropriate expression of chondroitin sulfate A (CSA).

Abstract:
Herein is reported a conjugate of a haptenylated polypeptide toxin and an anti-hapten antibody, wherein a disulfide bond is formed between a cysteine residue either before or after the lysine residue that is used for hapten-conjugation and a cysteine residue in the CDR2 of the antibody, whereby the CDR2 is determined according to Kabat.

Abstract:
The present invention is directed to T-cell epitope delivering polypeptides which deliver one or more CD8+ T-cell epitopes to the MHC class I presentation pathway of a cell, including toxin-derived polypeptides which comprise embedded T-cell epitopes and are de-immunized. The present invention provides cell-targeted, CD8+ T-cell epitope delivering molecules for the targeted delivery of cytotoxicity to certain cells, e.g., infected or malignant cells, for the targeted killing of specific cell types, and the treatment of a variety of diseases, disorders, and conditions, including cancers, immune disorders, and microbial infections. The present invention also provides methods of generating polypeptides capable of delivering one or more heterologous T-cell epitopes to the MHC class I presentation pathway, including polypeptides which are 1) B-cell and/or CD4+ T-cell de-immunized, 2) comprise embedded T-cell epitopes, and/or 3) comprises toxin effectors which retain toxin functions.
Abstract:
A vaccine composition comprising a fusion protein for inducing enhanced pathogen antigen-specific T cell responses is disclosed. The fusion protein comprises: (a) an antigen-presenting cell (APC)-binding domain or a CD91 receptor-binding domain, located at the N-terminus of the fusion protein; (b) a translocation peptide of 34-112 amino acid residues in length, comprising an amino acid sequence that is at least 90% identical to SEQ ID NO: 4, 2, 3, or 6, located at the C-terminus of the APC-binding domain or the CD91 receptor-binding domain; and (c) an antigen of a pathogen, located at the C-terminus of the translocation peptide; (d) a nuclear export signal, comprising the amino acid sequence of SEQ ID NO: 13; and (e) an endoplasmic reticulum retention sequence, located at the C-terminus of the fusion protein.
