Transport of an antifungal trypsin inhibitor isolated from corn across the blood-brain barrier

Antimicrob Agents Chemother. 2002 Aug;46(8):2633-5. doi: 10.1128/AAC.46.8.2633-2635.2002.

Abstract

We determined whether an antifungal 14-kDa protein trypsin inhibitor isolated from corn is able to cross the blood-brain barrier. We found that it completely crossed the blood-brain barrier by means of a saturable mechanism at a rate of 0.153 microl/g. min, with about 0.082% of the intravenously injected dose being taken up per gram of brain.
