title: Attachment of adeno-associated virus type 3H to fibroblast growth factor receptor 1.
abstract: Heparan sulfate proteoglycan is thought to act as primary receptor for adeno-associated virus type 2 (AAV-2). Reported coreceptors include alphaVbeta5 integrin, fibroblast growth factor receptor 1 (FGFR-1), and hepatocyte growth factor (c-Met). The interaction of AAV type 3 (AAV-3) with possible cell membrane receptors is incompletely defined. In this study, using assays detecting competition with viral infection, virus binding inhibition assays and dot blotting, we show attachment of AAV-3 strain H to heparin, heparan sulfate, and FGFR-1. These findings provide new information on the possible receptor array used by AAV-3.
