Engineering CAR T cells expressing specific chimeric cytokine receptors that signal independently from the presence of an exogenous cytokine can significantly impact cancer cellular therapy
Engineering CAR T cells expressing specific chimeric cytokine receptors that signal independently from the presence of an exogenous cytokine can significantly impact cancer cellular therapy by improving : i) trafficking and expansion of the adoptive cells therapy product post-infusion, ii) extended persistence of the modified T cells post tumour eradication. Altogether, these features will allow lifelong tumour protection. Furthermore, the technology here illustrated holds the potential to reduce the dose required to reach therapeutic efficacy, greatly reducing the overall manufacturing cost. Finally, the generalisability of the architecture described holds the potential to tailor a specific cytokine signal to a particular type of cell that the developed therapy is based upon. Overall design: Comparative gene expression profiling analysis of RNA-seq data for T cells treated with recombinat IL2, Constitutive Chimeric cytokine receptor delivering IL2 signal (FabIL2), or no treatment.
