Abstract

Although the adeno-associated virus type 2 (AAV) is known to possess a broad host range that transcends the species barrier, we suggested in an earlier study that AAV infection of human cells is receptor mediated (S. Ponnazhagan et al., J. Gen. Virol. 77:1111-1122, 1996). In the present studies, we investigated the ability of AAV to infect primary human hematopoietic progenitor cells capable of multilineage differentiation. Bone marrow-derived CD34+ cells from 12 hematologically normal volunteer donors were infected with a recombinant AAV containing the β-galactosidase gene under the control of the cytomegalovirus immediate-early promoter (vCMVp- lacZ). Whereas 15 to 80% of the cells from approximately 50% of the donors showed various levels of lacZ gene expression, the expression was undetectable in cells from the remaining donors. However, if cells from both sets of donors were stimulated with various combinations of cytokines to induce differentiation into myeloid and lymphoid lineages following AAV infection, then the level of expression of the transduced gene increased up to 20-fold over a period of 14 days. The results of virus-binding assays suggested that the observed difference between the two groups was due to the differential susceptibility of CD34+ cells to AAV infection rather than to differences in transcription and translation of the transduced gene. To corroborate these results, CD34+ cells from the two donor groups, KB (human nasopharyngeal carcinoma) cells, and M07e (human megakaryocytic leukemia) cells were infected with vCMVp-lacZ. KB cells served as a positive control for AAV infection, and M07e cells served as a negative control. Whereas abundant hybridization to the single-stranded viral DNA on Southern blots was detected in KB and CD34+ cells that were positive for lacZ gene expression, little activity was detected in M07e and CD34+ cells that did not show expression of the lacZ gene. These results suggest that the levels of expression of the putative cellular receptor for AAV vary widely in CD34+ cells from different donors. These studies have implications for the potential use of AAV vectors in human gene therapy involving primary human primitive hematopoietic stem and progenitor cells.
