Abstract: The present disclosure provides proteins, such as antibodies, that include an antigen binding portion that specifically binds to Programmed Death 1 Ligand 1 (PD-L1). Also provided are nucleic acids encoding the proteins, and cells (e.g., genetically modified cytotoxic lymphocytes) that include such nucleic acids. In some embodiments, a subject method includes reducing the interaction between PD-L1 on a first-cell and PD-1 on a second cell. In some cases, the contacting is in vivo. For example, the methods and compositions provided can be used in the treatment of viral infection and cancer, such as the treatment of solid tumors via ACT or via administration of a subject protein that specifically binds to PD-L1.

Abstract: Provided herein are predictive biomarker signatures that identify patients as likely to benefit from TIL therapy. Also provided are tumor immunotherapy resistance pathways that may be targets of combination therapies to enhance TIL therapy.

Abstract: BTLA-positive (“BTLA+”) lymphocyte signaling drives T cells and kills tumors. BTLA functions as a positive modulator of anti-tumor (anti-melanoma) T cell responses, The BTLA+ T cell responds against tumor or cancer cells, and, in cancer patients respond better to IL-2 than BTLA-negative cells. Hence, the BTLA-positive T cell in cancers is a positive marker for selection of enriched anti-tumor-cancer reactive T cells and can be used or applied for adoptive T-cell therapy or for therapeutic purposes.

Abstract: The present invention relates to a nucleic acid encoding a polypeptide and the use of the nucleic acid or polypeptide in preventing and/or treating cancer. In particular, the invention relates to improved vectors for the insertion and expression of foreign genes encoding tumor antigens for use in immunotherapeutic treatment of cancer.

Abstract: The technology relates to monoclonal antibodies useful in the identification of cancer cells. In one embodiment, mAbs with specificity for tumor antigens are provided. In one embodiment, methods for treating cancer using mAbs are provided. In another embodiment, methods for detecting cancerous cells are provided. In another embodiment, kits for detecting cancerous cells are provided.
