Most of this volume is dedicated to a very important and pragmatic issue which is to design ways of internalizing active pharmacological compounds into cells. In fact, many vectors have now been developed and the improvement in the technology can be seen on two main fronts. A first one is the identification of extremely efficient cargoes, for example siRNAs, which can enter the cells once attached to the vectors. A second one is the development of chemical vectors designed after the properties of the peptides and of tags allowing in vivo addressing to specific organs, for example the brain, cell types or sub-cellular compartments. This chapter is of a different nature, as it is devoted to the physiological significance of protein transduction and to the comparative analysis of the Penetratin PTD with its parental proteins, the homeoproteins. Although very academic, these two issues are of practical interest for the rational design of new vectors and the identification of unforeseen pathological mechanisms and pharmacological targets.
