Research on intracellular antibody delivery (Angew. Chem. Int'l Ed, 49(10) 2552-2555 (2010)) was highlighted in Science-Business eXchange (SciBX) Journal published by Nature Publishing Co.
In vitro studies suggest that polyionic micelles could efficiently deliver therapeutic antibodies into the interior of cells. Micelles consisting of a polyethylene glycol (PEG)-based cationic polymer and loaded with a highly anionic IgG were internalized by cells and degraded at intracellular pH to release their IgG payload into the cytosol (Y. Lee, et al, Angew. Chem. Int'l Ed, 49(10) 2552-2555 (2010)) .
