Compositions and methods for increasing the receptor mediated transport of basic fibroblast growth factor (bFGF) across the blood brain barrier (BBB). The bFGF is conjugated to a BBB targeting agent using either avidin-biotin technology or genetic engineering. The bFGF conjugate was found to cross the BBB at substantially increased rates while still retaining biological activity. In addition, uptake of the bFGF conjugate by non-brain tissue and organs was limited. The bFGF conjugate may be injected intravenously to provide neuroprotection in patients suffering from cerebral stroke. |
