AB A study was initiated to determine the function of Nef auxiliary protein
replication of HIV. A molecular clone of HIV, LAI, was selected and two
truncated (termination at amino acid 46 and 88) nef mutant clones
constructed. The proviral DNA of the mutants and wild type were used to
transfect Hela cells. Virus produced in Hela cells was passaged onto
primary T4 lymphocytes and virus stocks generated for replication
kinetic studies. The cells were infected at different multiplicities of
infection (MOI). The results indicate that the nef mutant clones are
slower in their ability to replicate at low MOI in both primary cells.
However, at MOI of 1, there was no difference in the replication
kinetics of wild type and nef mutants. This highlights the different
effects of the Nef if different MOI are used. We conclude that the Nef
protein is a positive factor at low MOI.
