Abstract: Provided herein are novel anti-EMP2 antibodies useful for the treatment and diagnosis of cancers that express or overexpress EMP2. In one aspect, provided herein is an isolated antibody that binds to Epithelial Membrane Protein 2 (EMP2), that includes heavy chain variable region and a light chain variable region. The heavy chain variable region includes three heavy chain complementary determining regions (HCDRs) and the light chain variable region includes three light chain variable regions (LCDRs). In some embodiments, the sequence of HCDR1 is SEQ ID NO: 11, the sequence of HCDR2 is SEQ ID NO: 12, the sequence of HCDR3 is SEQ ID NO: 13, the sequence of LCDR1 is SEQ ID NO:14, the sequence of LCDR2 is SEQ ID NO: 15, and the sequence of LCDR3 is SEQ ID NO: 16.

Abstract: Provided herein are compositions and methods for the treatment of a cancer in a subject having such a cancer (e.g., a breast cancer). In particular, the compositions provided herein include an anti-EMP2 antibody and a PD-1/PD-L1 pathway antagonist.

Abstract: Reduction of EMP2 expression and/or anti-EMP2 therapy reduces cancer stem cells in multiple types of cancer. For example, breast cancers stem cells were defined by the presence of HIF-1?, CD44 and ALDH. It is found that anti-EMP2 IgG1 can be used to reduce the numbers of cancer stem cells.

Abstract: The present invention provides methods and compositions useful in the treatment or prevention of Chlamydia infections and cancer. The methods and compositions inhibit the entry of Chlamydia into a host cell expressing EMP2 by interfering with the interaction between the Chlamydia and EMP2. The methods and compositions target cancers which express or overexpress EMP2 nucleic acids and polypeptides by targeting EMP2.

Abstract: Disclosed herein are methods and compositions for modulating neovascularization. The disclosed compositions find particular use in the treatment of uterine cancers, specifically endometrial cancers.

Abstract: Despite advances in therapy, breast cancer remains the most common malignancy in women. Of particular concern is the aggressive triple negative subtype that lacks the BRCA1 mutation, estrogen receptor, and epidermal growth factor type 2 receptor (Her-2/neu), which accounts for approximately half of all breast cancer deaths. Provided herein are compositions and methods for treating breast cancer, including the triple negative subtype.
