There is evidence that the filovirus glycoprotein plays an important role in cell tropism, spread of infection, and pathogenicity. Biosynthesis of the glycoprotein forming the spikes on the virion surface involves cleavage by the host cell protease furin into two disulfide linked subunits GP1 and GP2. GP1 is also shed in soluble form from infected cells. Different strains of Ebola virus show variations in the cleavability of the glycoprotein, that may account for differences in pathogenicity, as has been observed with influenza viruses and paramyxoviruses. Expression of the spike glycoprotein of Ebola virus, but not of Marburg virus, requires transcriptional editing. Unedited GP mRNA yields the nonstructural glycoprotein sGP, which is secreted extensively from infected cells.

This method was essentially unaltered until the late 1940s when the important experiments by Frenkel in Holland showed that the quantities of virus required for vaccine production could be obtained from fragments of tongue epithelium incubated in vitro following infection with the virus. This major step made possible the comprehensive vaccination programmes which followed in Western Europe and which, in turn, resulted in the elimination of the disease from that part of the world by 1989. This spectacular success has led many to question whether other kinds of vaccine are required to control the disease worldwide. Such reservations ignore the danger to the environment associated with the growth of large amounts of virus. This can never be a zero-risk situation. Consequently, a vaccine which is not based on infectious virus as starting material has many attractions from safety considerations alone. In addition, a vaccine based on more fundamental considerations would not only be more aesthetically satisfying but could possibly provide an understanding at the molecular level of antigenic variation, still a problem in the control of the disease. The advances in our knowledge of the structure of the virus and the fragments which elicit a protective immune response now allow us to envisage a vaccine which does not require infectious virus and which protects against the multiple serotypes of the agent. Since antigenic variation is still a major problem in the control of the disease by vaccination, such a product would have important advantages over the current vaccines.</p>","PeriodicalId":77010,"journal":{"name":"Archives of virology.

Contributions to the field of veterinary virology were not considered here, since this topic was treated separately during this centennial symposium. The overview includes contributions of the very early period when interest was focussed mainly on the determination of the physicochemical properties of the fast growing number of newly detected viruses, and of the pioneering period when fundamental discoveries of the nature of viruses were made. The concepts that derived from those studies made the development of modern virology possible. Some highlights of the present period were presented describing the findings of selected virus families. This part was followed by a description of the results which were relevant to problems of how viruses become pathogens, and the role of the immune response to virus infections. Finally, attention was drawn to the contributions of molecular studies which became important not only for the field of virology but also for life sciences in general.</p>","PeriodicalId":77010,"journal":{"name":"Archives of virology.

Work on these problems may offer no obvious practical justification; it is an affliction of the terminally curious, perhaps with the outside hope that something \"useful\" will come of it. To do this so-called \"basic science\", one must find the most tractable system to solve the problem, not the system that has \"relevance\" to disease.
