Abstract:
:There have been remarkably rapid advances in the understanding of prion diseases over the past year. The controversial notion that the transmissible agent may be an abnormal isoform of a host-encoded protein, the prion protein, is now gaining wide acceptance. The conundrum of how a disease can both be inherited as an autosomal dominant condition and also be experimentally transmissible by inoculation is beginning to make sense.

Recent studies suggest that in mammalian cells inter-chromosomal DNA interactions may mediate the decision which allele to activate and which to silence.
