- Development of potent class II transactivator gene delivery systems capable of inducing de novo MHC II expression in human cells, in vitro and ex vivo(2017) PALMA, M. L.; DUANGKHAE, P.; DOURADINHA, B.; VIANA, I. F. T.; RIGATO, P. O.; DHALIA, R.; MAILLIARD, R. B.; BARRATT-BOYES, S. M.; NASCIMENTO, E. J. M.; OSHIRO, T. M.; DUARTE, A. J. da Silva; MARQUES, E. T. A.Class II transactivator (CIITA) induces transcription of major histocompatibility complex (MHC) II genes and can potentially be used to improve genetic immunotherapies by converting non-immune cells into cells capable of presenting antigens to CD4(+) T cells. However, CIITA expression is tightly controlled and it remains unclear whether distinct non-immune cells differ in this transactivator regulation. Here we describe the development of gene delivery systems capable of promoting the efficient CIITA expression in non-immune cell lines and in primary human cells of an ex vivo skin explant model. Different human cell types undergoing CIITA overexpression presented high-level de novo expression of MHC II, validating the delivery systems as suitable tools for the CIITA evaluation as a molecular adjuvant for gene therapies.
