HIV-1 V3 loop clones of virus isolates derived from patients suffering from thrombocytopenia were used for infection of the human thymus/liver conjoint hematopoietic organ that developed in the severe combined immunodeficient mouse (SCID-hu Thy/Liv). The V3 loop clones showed a significantly greater degree of inhibition of megakaryopoiesis than myelopoiesis and erythropoiesis of the human CD34+ progenitor cells, in vivo. Inhibition of megakaryopoiesis occurs through reduction in c-Mpl expression and consequent decrease in STAT5 activation. Therefore HIV-1 V3 loop sequences of thrombocytopenic patients exhibit preferential inhibition of megakaryocyte lineage-specific differentiation of CD34+ progenitor cells, thus reflecting the patients' clinical condition.
