    • Protease-resistant and detergent-insoluble prion protein is not necessarily associated with prion infectivity
    • C into protease-resistant and detergent-insoluble PrP molecules is not the only crucial step in prion replication. The authors speculate that an additional requirement may be the aggregation of newly formed PK-resistant PrP molecules into uniquely structured aggregates.

    • Quantifying the kinetic parameters of prion replication
    • RES appears to be slower than growth in infectious titre, a phenomenon that can be explained either by a novel hypothesis concerning inoculum clearance from a newly infected brain or by the faster growth of compartments containing smaller polymers. Published kinetic data are all compatible with the presented mathematical model, so the nucleated polymerisation hypothesis cannot be ruled out on dynamic grounds.

    • Surgical treatment and risk of sporadic Creutzfeldt-Jakob disease: A case-control study
    • To examine risk factors for sporadic CJD, the medical history and demographic characteristics of 241 patients and 784 controls were assessed. Surgical procedures were significantly associated with the development of sporadic CJD, with the risk progressively increasing with the number of surgical treatments. The findings accord with the hypothesis that a range of surgical treatments may serve as an unrecognised contamination event and account for a proportion of the cases of sporadic CJD.

    • Expression of amino-terminally truncated PrP in the mouse leading to ataxia and specific cerebellar lesions
    • Mice devoid of PrP develop normally, but are resistant to scrapie; introduction of a PrP transgene restores susceptibility to the disease. In order to identify the regions of PrP that are necessary for this activity, PrP knockout mice expressing PrPs with amino-proximal deletions were made. Surprisingly, PrP lacking residues 32-121 or 32-134 caused severe ataxia and neuronal death as early as 1-3 months after birth, but shorter deletions did not. The defect was completely abolished by introducing one copy of a wild-type PrP gene. The authors speculate that these truncated PrPs may be nonfunctional and compete with some other molecule with a PrP-like function for a common ligand.

    • Prion protein of 106 residues creates an artificial transmission barrier for prion replication in transgenic mice
    • Sc produced disease in these mice after 300 days, whereas transmission of PrP-106 prions created disease in the same mice after only 65 days on repeated passage. The unique features of this truncated form of PrP offer insights into the mechanism of prion replication and the small size of PrP-106 should facilitate structural analysis.
