Although the precise physiological role of PrPSc and the chemical differences between PrPSc and normal Prion protein (PrP) remain unknown, it appears that the differences are conformational (Prusiner, 1998). A. Keywords: Prions; biochemical weapons; Prion diseases; Prions danger to the environment; Prions risk alert. (2009). In addition, the decontamination of the environment can be a huge problem if Prions are not rapidly degraded in the soil by microorganisms; some studies have demonstrated that the soil is as possible reservoir of scrapie and CWD agents, which can persist in the environment for years. http://dx.doi.org/10.1126/science.1183748        [ Links ], Wasmer, C., Lange, A., Van Melckebeke, H., Siemer, A.

Prions cause fatal infectious diseases, and to date there is no therapeutic or prophylactic approach against these diseases. The link between prions and copper was first noticed back in 2009, and now the Iowa State team has shown in molecular detail exactly how the two interact.

People have had a passion for weapons of mass destruction since the government military agencies search for chemical weapons culminating with the use of poisonous gases in the First War.

These results suggest that the regions of a proposed secondary structure in PrP and the disulfide bond stabilizing helices 2 and 3 are required for PrPSc formation (Rogers et al., 1993; Fischer et al., 1996; Muramoto et al., 1996).
