Virus. description Although they reproduce, they can only do so only by entering a host cell and making use of its machinery for replication. Viruses are bits of genetic material, apparentlyderived from their hosts. Thus, as Margulis and Schwartz (1988) put it, the polio and flu viruses are probably more closely related to people, and the tobacco mosaic virus (TMV) to tobacco, than polio and TMV are to each other

Prion. description Prions are pathogenic variants of proteins that are naturally produced in nerve cells and certain other cells. The normal healthy prions are referred to as PrPc 0roteinaceous infectious particle and so should properly only be applied to the pathogenic variants. RNA that codes for PrPc is produced in the nucleus and exits via the nuclear pore. The RNA then passes along ribosomes attached to the rER. PrPc is formed in the rER and then progresses up through the Golgi. At the upper face of the Golgi, vesicles containing PrPc bud off and travel to the cell surface. Here, they fuse with the cell membrane and so discharge their cargo at PrPc. By this means, the cellular proteins come to sit on the exterior of the cell.

PrPc encounter rogue (purple) prions. These are termed PrPsc (sc stands for scrapie, the prion disease of sheep). The rogue prions seem to force the normal proteins to change shape. Both types of protein, the PrPc and their corresponding prions, are the same chemical - just different shapes. It is this shape-flipping which is equivalent to the transmission of infection. Such a conformational shift or flip could happen at the cell surface or in caveolae (one is shown as a small invagination in the cell membrane). Residual PrPc might continue to be flipped by contact with the rogue confomations for some time in these vesicles.

Prions polymerise, finally appearing as purple fibrils in the picture at P. PrPsc is resistant to degradation by the enzymes contained in the lysosomes that are seen floating nearby. Consequently, PrPsc accumulates in the cell. PrPsc vesicles may also travel to the Golgi and intercept PrPc that is being processed there. In this way, PrPc particles could be switched to the rogue form before they reach the surface of the cell. By such mechanisms, PrPc might be switched to PrPsc at various points in and on the cell. It must be emphasised that prion biology is not fully understood and much remains speculative
