520	3		_aWe have developed a novel procedure in which a small collagen sheet (3mm×3 mm)absorbing prion-infected brain homogenates was transplanted onto the brain surface of highly prion-susceptible transgenic mice (Tg(MoPrP)4053/FVB), as an animal model of iatrogenic Creutzfeldt- Jakob disease (iCJD)caused by prion-contaminated cadaveric dura graft transplantation. Using the iCJD model, we further investigated the in vivo efficacy of dominant negative recombinant prion protein with lysine substitution at mouse codon 218 (rPrP-Q218K), which is known to inhibit prion replication in vitro (H. Kishida, Y. Sakasegawa, K. Watanabe, Y. Yamakawa, M. Nishijima, Y. Kuroiwa, N.S. Hachiya, K. Kaneko, Non-glycosylphosphatidylinositol (GPI)-anchored recombinant prion protein with dominant-negative mutation inhibits PrPSc replication in vitro, Amyloid, vol. 11, 2004, pp. 14-20.). Following 7-day intracerebroventricular administration of the rPrP-Q218K via an indwelling catheter connected to the implanted osmotic pump, the median incubation period of Tg(MoPrP)4053/FVB was prolonged considerably from 117 days to 131 days (p = 0.016, log-rank test)in the rPrP-Q218K-treated group, even after a lengthy latency period of as long as 30 days by starting the rPrP-Q218K injection. Whether wild-type rPrP, other mutant rPrPs, or the combination of rPrP-Q218K with other anti-prion compounds might extend the survival period in that condition must be further investigated.
