Serum has often been reported as a barrier to efficient lipidmediated transfection. Here we found that the transfection efficiency of DC-Chol–DOPE/DNA lipoplexes increases in serum. Our results suggest that ‘protein corona’ can promote large aggregation of intact lipoplexes resulting in a switch from a clathrin-dependent to caveolae-mediated entry pathway into the cells which is likely to be responsible for the observed transfection efficiency boost.

Abstract
Serum has often been reported as a barrier to efficient lipidmediated transfection. Here we found that the transfection efficiency of DC-Chol–DOPE/DNA lipoplexes increases in serum. Our results suggest that ‘protein corona’ can promote large aggregation of intact lipoplexes resulting in a switch from a clathrin-dependent to caveolae-mediated entry pathway into the cells which is likely to be responsible for the observed transfection efficiency boost.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
