This invention relates to compositions and methods for increasing the uptake of polynucleotides into cells. Specifically, the invention relates to vectors, targeting ligands, and polycationic agents. The polycationic agents are capable of (1) increasing the frequency of uptake of polynucleotides into a cell, (2) condensing polynucleotides; and (3) inhibiting serum and/or nuclease degradation of polynucleotides.
La présente invention se rapporte à des compositions et à des procédés d'accroissement de l'apport de polynucléotides à des cellules. De manière spécifique, l'invention se rapporte à des vecteurs, à des ligands d'acheminement vers une cible et à des agents polycationiques. Lesdits agents polycationiques sont capables (1) d'accroître la fréquence d'apport de polynucléotides à une cellule, (2) de condenser les polynucléotides et (3) d'inhiber la dégradation des polynucléotides par le sérum et/ou des nucléases.
