Study data from University of Oxford update understanding of adenovirus
July 1st, 2009
"Adenovirus type 5 (Ad5) gene therapy vectors require protection against antibodies, complement proteins and blood cells if they are to be delivered intravenously to treat metastatic disease. Such protection can be achieved by chemically modifying Ad5 with polymers based on hydrophilic HPMA," scientists writing in the Journal of Controlled Release report. "Here, such polymers were designed to include side chains bearing reactive carbonyl thiazolidine-2-thione groups (TTs) to covalently modify available amino groups of the lysine residues in the Ad5 capsid. Furthermore, the inclusion of side chains bearing positively charged quaternary ammonium groups (QAs) was...
