Transgenic animals and prion diseases

Abstract

Extract

Thank you for the opportunity to respond to Peter Wills's letter on transgenic animals and prion diseases. Dr Wills has written an interesting letter, but the reader must note that only extreme cases are being argued. No biotech process has yet sought to produce a biological molecule which is non-native to the transgene, and to suggest, for example, that transgenic sheep producing human growth hormone will produce an aberrant protein of pathological potential is stretching a point.
