Abstract

(1), we investigated the interaction ofbaculovirus and mammalian cell surface heparan sulfate pro-teoglycans (HSPG). The data show that baculovirus requiresHSPG sulfation, particularly N- and 6-O-sulfation, to bind andtransduce mammalian cells. We also show that baculovirus asso-ciates specifically with syndecan-1 (SDC-1) but not with othersyndecans or glypicans.As discussed in the article, HS has previously been shown to beinvolved in glycoprotein 64 (gp64)-mediated baculovirus bindingonto mammalian cells. Heparin and heparinase I and II treatmentof cells have also been shown to prevent the virus binding (2, 3).The role of HS in baculovirus entry was further studied in ourarticle (1). Binding and baculovirus-mediated gene delivery wereseen to decrease after NaClO
