SO Annu Conf Australas Soc HIV Med. 1993 Oct 28-30;5:112 (poster no. 73). Unique Identifier : AIDSLINE ASHM5/94348932 AB We have developed a computational tool for biological research to study the replication strategy of the human immunodeficiency virus. This model incorporates a formal model using Petri Nets and scientific citations. In the development of the formal model we have uncovered some facets of the replication strategy that warrant further investigation due to the incompleteness of current knowledge. A detailed understanding of the replication strategy allows better definition of steps that might be amenable to novel antiviral development. Modelling this strategy on the computer facilitates formulating and testing hypotheses at a theoretical level and organising the burgeoning HIV literature within the structure of this easily interpreted model. Application of this to modelling roles for the HIV auxiliary proteins revealed details of Tat, Rev and Nef functions yet to be resolved.
