RNA Transfer by Electroporation into Mature Dendritic Cells Leading to Reactivation of Effector-Memory Cytotoxic T Lymphocytes: A Quantitative Analys…

2005

Previous studies have analyzed transfer of RNA-encoded tumor-associated antigens (TAAs) into immature dendritic cells (DCs) because of their exceptional ability to internalize antigens. Concerns have been raised regarding the use of immature DCs in clinical studies because of their capacity to tolerize T cells. Therefore, we focused on optimizing RNA transfer into mature DCs using the method of electroporation and obtained high protein expression in 90% of mature DCs. Particular emphasis was placed on quantifying RNA transfer. Reconstitution of peptide-MHC (pMHC) ligands on RNA-pulsed DCs was measured with the help of effector-memory cytotoxic T lymphocytes (CTLs) specific for the melanoma-…
