For the duration of the viral replication cycle, assumed to be about T=36 h (the lifetime of a productively infected CD4+ T cell [20]), the following global characteristics of co-infection were computed for various combinations of MOI and number of TIP-2 entering the cell:(65)[Vtot]≈[Vnew](36h),[TIPtot]≈[TIPnew](36h),[HIV−TIPtot]≈[HIV−TIPnew](36h). Here, CD4 is linked to coinfection.
