Telomerase reverse transcriptase (TERT)

A mouse study suggests adoptive transfer of
T cells expressing a TERT-specific T cell receptor (TCR) and additional small interfering RNAs could help treat adult T cell leukemia (ATL). A retroviral vector was engineered to express both a TERT-specific TCR and siRNAs that suppressed expression of endogenous TCRs, then transduced into CD8+ T cells. In mouse models for ATL, infusion of autologous or allogeneic
T cells modified with the vector decreased tumor growth compared with infusion of unmodified cells. Next steps include determining whether the approach could be toxic to TERT-expressing normal tissues and measuring the proliferation of the adoptive T cells in vivo.
