Abstract

"LIPOSSOMAS PH-SENSìVEIS PARA TRANSPORTE DE áCIDOS NUCLéICOS E SEU PROCESSO DE OBTENçãO". Esse sistema de transporte de ácidos nucléicos apresenta uma elevada taxa de encapsulação, homogeneidade de diâmetro das vesículas e podem permitir uma eficaz expressão gênica, inibição da transcrição e/ou tradução, além de reduzida ou ausência de citotoxicidade. Os lipossomas pH-sensíveis são constituídos por complexo de ciclodextrina catiónica/ácidos nucléicos, fosfolípes formadores de fases não lamelares ou misturas de lamelares e não lamelares, compostos estabilizadores contendo grupamentos aniónicos juntamente ou não com fosfolípide acoplado à cadeia de polietilenoglicol.
