Induction of specific human cytotoxic T cells using dendritic cells transduced with an adenovector encoding rat epidermal growth factor receptor 2.

This study demonstrates the ability to generate antigen-specific cytotoxic T cells (CTLs) against HER2 using a xenoantigenic immune stimulation strategy. Dendritic cells (DCs) were transduced with an adenovirus vector incorporating full-length cDNA for rat (xenoantigen) epidermal growth factor receptor 2 (Adv-HER2). Stimulation of autologous T cells with Adv-HER2 infected DCs led to enhanced HER2-specific reactivity as assessed by quantitative …
