RESUMO
The role of the host cell cycle in determining the efficiency of infection with amphotropically packaged retroviral vectors was investigated in T lymphocytes and in fibroblasts. For T lymphocytes, the efficiency of infection with a retroviral vector was dependent on the cell cycle distribution of cells in culture at the time of exposure to the vector. When cultures enriched in the G0-G1 phase of the cell cycle (by serum starvation, aphidicolin treatment, or centrifugal elutriation) were exposed to retroviral vectors, the infection efficiency was severalfold lower than that in similar cultures enriched in the S, G2, and M phases. For fibroblasts, the efficiency of infection was not cell cycle dependent. These findings are relevant for studies with retrovirus-mediated gene transfer into hematopoietic tissues.
