High Affinity Monoclonal Antibodies Targeting Glypican-2 for Treating Childhood Cancers

Neuroblastoma is a rare pediatric cancer with approximately 1,000 new cases arising annually. Current therapies have a less than forty-five percent (45%), three-year survival rate which demonstrate a need for a more effective treatment against this disease. Glypican-2 (GPC2) is a cell surface protein that is preferentially expressed in pediatric cancers including neuroblastoma, which makes GPC2 an...

Anti-SLAMF7 Chimeric Antigen Receptors

Immortalization of plasma cells leads to Multiple Myeloma (MM). Signaling Lymphocyte Activation Molecule F7 (SLAMF7) is highly expressed on the malignant plasma cells that constitute Multiple Myeloma. The expression of SLAMF7 by MM cells and lack of expression on nonhematologic cells makes SLAMF7 a promising target for chimeric antigen receptor (CAR) T cell therapies for the treatment of MM.  In ...

New Insect Sf9-ET Cell Line for Determining Baculovirus Titers

The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell. The current...

Potassium Hydroxy Citrate Promotes Longevity and Efficacy of Anti-Tumor T cells for Adoptive Cell Therapy (ACT)

Adoptive cell therapy (ACT) using tumor-specific T cells can produce positive clinical responses in some cancer patients. Nevertheless, several obstacles to the successful use of ACT for the treatment of cancer and other conditions remain. For example, one or more of the in vivo persistence, survival, and antitumor activity of tumor-specific T cells can, in some cases, decrease following adoptive ...

Rapid Manufacture of Retroviral Vectors Encoding Tumor-Specific T Cell Receptors for Adoptive Cell Immunotherapy

Human cancers contain genetic mutations that are unique to each patient. Some of the mutated peptides are immunogenic, can be recognized by T cells, and may serve as therapeutic targets. However, there are technical barriers making it difficult to engineer tumor-specific T cells unique to each patient. Thus, there is a need for new methods of producing these T cells in sufficient quantities to pro...

Therapeutic Antitumor Combination Containing TLR4 Agonist HMGN1

Immune checkpoint inhibitors (e.g. CTLA-4, PD-L1) have recently shown significant promise in the treatment of cancer.  However, when used alone, these checkpoint inhibitors are limited by the absence or repression of immune cells within the targeted cancer.  For those cancers associated with these limited immune systems, there remains a need for effective therapies.  Agents capable of recruitin...

T-Cell Receptors Targeting Kita-Kyushu Lung Cancer Antigen 1 (KK-LC-1)

Development of T-cell based immunotherapies for the treatment of various cancers has been challenged for decades by the lack of target antigens that are only expressed by cancer cells and not normal tissues. KK-LC-1 belongs to a family of tumor antigens known as cancer-testis antigens, which have restricted expression in immune-privileged germ cells and various cancers, and not in normal life-esse...

Highly Soluble Pyrimido-Dione-Quinoline Compounds: Small Molecules that Stabilize and Activate p53 in Transformed Cells

The tumor-suppressor p53 protein plays a major role in tumor development. Most human cancers fail to normally activate wild-type p53, which is at least partly responsible for the unregulated growth of cancer cells and their failure to undergo apoptosis. While many chemotherapeutics enhance p53 levels, their non-specific DNA damage (genotoxicity) causes unfavorable side effects.   Defects in the...

The UBE2G2 Binding Domain in the Ubiquitin Ligase GP78 and Methods of Use Thereof
