TS-000969 — Gene therapy experts at Nationwide Children’s Hospital have made significant advancements in designing optimal viral vectors for producing Good Manufacturing Practice (GMP)-grade viral vector products. Adeno-associated virus (AAV) serotypes such as AAV1, 2, 2.5, 3, 5, 6, 8, 9 and rh74 have properties optimized by these researchers. Chimeric Antigen Receptor T cells (CAR T) are comprised of an extracellular antigen recognition domain, intracellular T cell activation and co-stimulatory domains. These cells allow for potent and specific targeting of cancer cells, bypassing the need for antigen presentation and T cell receptor recognition. Generating CAR T cells using the process of lentiviral transduction has limitations stemming from the random integration of transgenesis, where oncogene activation, gene silencing, or negative effects on the CAR T antitumor efficacy are possible.

TS-000906 — Natural Killer (NK) cells express a range of receptors to activate or inhibit certain cellular behavior to kill cancer cells. Additionally, CD38 presenting cells have been used as a marker for cancer stem cells, specifically those that often avoid recognition when common surface antigen processes are used. CARK1 is a phosphorylate that impacts cell growth and development. A team led by Dr. Dean Lee has developed CD38k0 NK cells that they combine with CARK1 to create a series of monoclonal antibodies that targets cancer cells. Along with better cell targeting, this combination improves the efficacy of treatment in comparison to the CAR, NK, or CD38 antibodies as independent components.

TS-000857 — CD33 is a receptor that spans multiple membranes and is expressed on myeloid lineage cells and sometimes lymphoid cells. A team of researchers led by Dr. Dean Lee have found a new way to modify existing CD33 processes to provide Natural Killer (NK) cells the additional ability to recognize cell targets expressing CD33. Acute Myeloid Leukemia (AML) expresses multiple antigens, where CD33 is the most common. This new process, labeled as CD33-CAR, shows a significant advantage in targeting AML that presents with CD33, especially in cases that resist unmodified NK cells.

TS-000446 — Airway epithelial cells (AECs) in the lungs play a crucial role in maintaining a conduit for air and defend against pathogens. Various acute and chronic pulmonary diseases damage AECs resulting in their altered structure and function. However, the AEC renewal is a slow process. Researchers at Nationwide Children’s Hospital have generated Airway Epithelial Stem cells using gene editing technology that will provide unlimited cell source for AECs. Notably, these cells evade immune rejection in recipients. This preclinical invention may provide “off-the-shelf” product paving the way to regenerative respiratory therapeutics.
