Abstract

Abstract: HIV infection affects dendritic cells (DCs) number, maturation, and function although the cause remains largely unknown. Purified CD34+ hematopoietic progenitor cells (HPCs) obtained from bone marrow of chronic HIV-infected patients were investigated for the differentiative capability toward mature DCs. HIV, although not in active replication, was found able to impair CD34+ HPC differentiation into mature DCs. These results suggest that DCs impairment found in HIV-infected patients may be related to a failure by bone marrow CD34+ HPCs to produce an adequate number of DCs.
