TS-000972 — Natural Killer (NK) cells express a range of receptors to activate or inhibit certain cellular behavior to kill cancer cells. When an NK cell is deficient or dysfunctional, the efficiency of the NK cells is severely limited. VISTA is a protein sequence that activates T cells and acts as a moderator for the immune system. It has low-to-moderate expression but has been the target of study by a team of researchers at Nationwide Children’s Hospital led by Dr. Dean Lee. By removing VISTA in expanded NK cells, the inhibitory signal will be eliminated and thus resulting in an enhanced ability of NK cells to target cancers and overcome the immune-suppressive signals for improved cancer immunotherapy.

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-000638 — One of the most promising forms of cancer gene therapy is delivery of genes directly to the tumor to facilitate cancer cell death. Gene therapy experts at Nationwide Children’s Hospital have developed a tumor-targeted novel molecular treatment by fusing two genes, Survivin and Granzyme B. Survivin is expressed at high levels in all tumors and Granzyme B induces apoptosis in tumor cells. The recombinant DNA is delivered to the target cells by another agent, such as liposome. This approach represents a universal method for targeting tumor cells that express Survivin and induce death of those cells, leaving minimal effect on healthy cells, unlike conventional chemotherapeutic approaches.
