2. Prion
   This is the protein that makes up the infectious agent claimed by a large number of groups now to be the infectious particle that transmits the disease from one cell to another and from one animal to another. It is made from the normal protein PrPc (the c stands for chromosomal) that is produced in small quantities on many cells and especially the lymphoid and nervous tissue cells.

10. prion
    The word, for proteinaceous infectious agent, was coined in 1982 by neurologist Stanley Prusiner as part of a hypothesis regarding ailments bearing aetiologic resemblance to those caused by slow viruses (for instance, kuru). The hypothesis has been borne out by investigation. Prions are now believed...
