90. In Vitro and In Vivo Gene Expression of Lentiviral Vectors in CD4+ T Cells

In certain applications of gene therapy, regulated (rather than constitutive) gene expression will be crucial for proper function or optimal effect of the delivered gene. Therefore, an important goal of gene therapy is to be able to deliver genes so that they express in a pattern that recapitulates the expression of an endogenous cellular gene. Additionally, regulating transgene expression will be an important component of efforts for reducing risks of adverse advents associated with gene therapy with integrating vectors.
