Summary

Automatic Translation

Upprepade retroorbital injektioner av katjoniska liposomes/siRNA/ITSN-1s komplex i möss, var 72 timmar för 24 dagar, effektivt leverera siRNA duplex till muslunga mikrovaskulaturen minska ITSN-1s mRNA och protein expression med 75%. Denna teknik är mycket reproducerbar i en djurmodell, har inga biverkningar och undviker dödsfall.
