The present invention provides methods for inhibiting interleukin-3 receptor-expressing cells, and, in particular, inhibiting the growth of such cells by using a diphtheria toxin-human interleukin-3 conjugate (DT-IL3) that is toxic to cells expressing the interleukin-3 receptor. In preferred embodiments, the DT-IL3 conjugate is a fusion protein comprising amino acids 1-388 of diphtheria toxin fused via a peptide linker to full-length, human interleukin-3. In certain embodiments, the methods of the present invention relate to the administration of a DT-IL3 conjugate to inhibit the growth of cancer cells and / or cancer stem cells in humans, which cells express one or more subunits of the interleukin-3 receptor. Exemplary cells include myeloid leukemia cancer stem cells. In other embodiments, the methods of the present invention relate to ex vivo purging of bone marrow or peripheral blood to remove cells that express one or more subunits of the interleukin-3 receptor such that the purged bone marrow or peripheral blood is suitable, e.g., for autologous stem cell transplantation to restore hematopoietic function.

InactiveUS6294381B1Artificial cell constructsImmunoglobulins against cell receptors/antigens/surface-determinantsCell lineageDendritic cell
Dendritic cells (DCs) are the primary antigen presenting cells during the initiation of T cell-dependent immune responses. The cells originate from the bone marrow and have been suggested to represent a distinct cell lineage. However, distinct DC precursors have not been identified in bone marrow, and mature monocytes can also give rise to DCs. The instant invention presents a distinct DC precursor among bone marrow CD34+ cells. The cells express high levels of the interleukin-3 receptor alpha chain and CD4 and can be uniquely identified also in blood and lymphoid tissues by this phenotype.
