TS-000973 — A recombinant oncolytic virus encoding either an adenosine deaminase or heterologous proteins can be used in treatment of a variety of diseases, as the primary purpose of these are to maintain and develop the immune system. A team of researchers at Nationwide Children’s Hospital have found a method that can address the delivery of adenosine deaminase into cancer cells, immune cells and the tumor microenvironment to aid in treatment for any disease or condition associated with adenosine or other associated markers.

TS-000738 — In all living cells, extracellular vesicles (EVs) are naturally produced. Drs. Kevin Cassady and Uksha Saini have developed a streamlined approach to utilize these EVs to deliver biologics and clinical drug treatments that permit repeated treatments without the possibility of limiting therapeutic delivery due to the natural immune response. This method produces an immune inert drug delivery system that, unless the EVs are designed to encode immunostimulatory molecules, should not invoke an immune response. Our preliminary studies show that we can load extracellular vesicles (EVs) with a therapeutic payload of our choice. Retroviruses co­opt and use much of the same pathways involved in cellular EV production for virus exit of the infected cell. We therefore hypothesized that Lentiviruses (a non-replicating retrovirus commonly used in the lab for gene expression) would provide a modifiable platform to generate therapeutic gene products that that would be preferentially transported and packaged into cellular EVs. This platform could then be modified and developed as a potential therapeutic delivery platform.
