A model of mixed infection of lymphoblastic cells of T-phenotype was first designed using HIV and some DNA-genomic viruses which may be associated with AIDS (Epstein-Barr virus belonging to Herpesviridae and human adenovirus type 2). Considerable dec­reasing of HIV infection Hires as well as Ad hexon and EBV capsid proteins formation under triple (HIV+ Ad+ EBV) or double (HIV +Ad, HIV + EBV) infection of MT4 cells in different versions of non-simultaneous consecutive introduction of each virus were revealed, while HIV p24 expression levels were unchanged. Reverse transcriptase activity decreases upon triple infection of MT4/BIII cells chronically infected by HIV and producing it, while superinfection of cells by Ad increases level of enzyme. Drastic decreasing of interferone production was observed upon triple infection of lymphocytes from HIV-infected pacients and MT4 cells. Obtained data on mutual interference of HIV, Ad and EBV upon joint infection of cells are important for HIV-infection mechanism understanding, especially in conditions of latent lymphotropic viruses broad circulation among population of Ukraine in con­temporary ecological conditions.
