- Cell Phenotype and Cytotoxicity: The cells expressed a predominant naïve-like memory phenotype with potent in vitro cytotoxicity and proinflammatory cytokine production against CD70+ tumor cell lines.
- Tumor Growth Inhibition: Significant inhibition of tumor growth was observed in CD70+ tumor cell lines, maintained even in the presence of TGF beta inhibitory factor.
- Resistance to Rejection: The therapy exhibited improved resistance to killing by host T cell rejection.
- Biodistribution: Marked biodistribution and infiltration into solid tumor models of renal cell carcinoma were demonstrated.
Guidance, Outlook, and Risks
