We demonstrate that natural killer (NK) cells induce a higher cytotoxicity against lung cancer stem-like cells (hA549) compared to differentiated lung cancer cell lines (H292). The supernatants from split-anergized NK cells (IL-2 and anti-CD16 mAb-treated NK cells) induced differentiation in hA549. Differentiated lung cancer cell line (H292) and NK cells differentiated hA549 expressed reduced NK cell-mediated cytotoxicity but expressed higher sensitivity to chemotherapeutic drugs.

The ability of natural killer (NK) cells to kill tumor cells without prior sensitization makes them a rising player in immunotherapy. Increased understanding of the development and functioning of NK cells will improve their clinical utilization.

Abstract The differentiation of natural killer (NK) cells and a subpopulation of NK cells which requires an intact thymus, that is, thymic NK cells, is poorly understood.

Herein, we generated and characterized NK cells differentiating from thymic DN precursors.

Abstract Natural killer (NK) cells are differentiated from hematopoietic stem cells (HSCs) in bone marrow. The differentiation of NK cells is regulated by various factors including soluble growth factors and transcription factors.

HSC-derived precursor NK (pNK) cells were further differentiated into mature NK (mNK) cells in the presence of IL-15 in vitro.

Abstract Introduction Allogeneic stem cell transplantation (SCT) can be a curative treatment for hematological malignancies. The therapeutic effectiveness is attributed to the graft-versus-tumor (GVT) effect, mediated by alloreactive T cells and natural killer (NK) cells. Although T cells can induce a potent GVT effect, they can also induce graft-versus-host disease (GVHD), causing high morbidity and mortality. Interestingly, after non-myeloablative allogeneic SCT, early NK cell repopulation has been associated with decreased relapse rates, without increasing GVHD incidence, illustrating a pos

Natural killer (NK) cells provide important host defense against microbial pathogens and can generate a population of long-lived memory NK cells after infection or immunization. Here, we addressed whether NK cells can expand and differentiate after alloantigen stimulation, which may be important in hematopoietic stem cell and solid tissue transplantation. A subset of NK cell in C57BL/6 mice expresses the activating Ly49D receptor that is specific for H-2Dd. These Ly49D+ NK cells can preferentially expand and differentiate when challenged with allogeneic H-2Dd cells in the context of an inflamm

Abstract To study the origin and differentiation of natural killer (NK) cells, we developed an assay for the transplantable precursor of NK(YAC-1) cells present in the bone marrow. Mice were depleted of endogenous NK(YAC-1) cells by injection of anti-asialo GM1 antibody, followed by lethal whole body irradiation. Normal syngeneic bone marrow cells were transplanted into such pretreated mice. Regeneration of NK(YAC-1) activity in the recipient mice was monitored by two different assays: the ability of spleen cells to lyse YAC-1 cells in vitro and the ability to clear i.v. injected, 125IUdR-labe

Abstract Introduction Natural Killer (NK) cells are lymphocytes that are important for early host defense against infectious pathogens and malignant transformation. NK cells differentiate from the CLP in the bone marrow, where they are identified by markers such as CD56 and NKp46 in humans, and NK1.1, CD122, and NKp46 in mice. NK cells further mature in the periphery, and this maturation is essential for NK cell function, as both NK cell cytotoxicity and IFN-g production are dependent upon maturation. NK cell maturation is distinguished by surface marker transitions, including CD56bright to CD

Abstract The cell lineage origin of IFN-producing killer dendritic cells (IKDCs), which exhibit prominent antitumoral activity, has been subject to debate. Although IKDCs were first described as a cell type exhibiting both plasmacytoid DC and natural killer (NK) cell properties, the current view reflects that IKDCs merely represent activated NK cells expressing B220, which were thus renamed B220+ NK cells. Herein, we further investigate the lineage relation of B220+ NK cells with regard to other NK-cell subsets. We surprisingly find that, after adoptive transfer, B220− NK cells did not acquire

Abstract Viable motheaten (mev) mice are homozygous for a recessive single gene mutation at chromosome 6. These mice develop numerous inflammatory and arthritic syndromes and exhibit abnormal B cell functions as well as lower T and NK cell activity. In this study, the differentiation of NK cells in mev mice was examined to elucidate the underlying basis for decreased NK activity. Although NK cells appear to be present in mev mice, their activity was demonstrable only when the spleen cells were enriched by nylon wool passage. Similarly bone marrow cells from these mice could be shown to contain

Abstract Natural killer (NK) cells play an important role in host defense against microbial infection and tumors. Previous studies showed that IL-15 is essential for NK cell differentiation in vitro and in vivo. However the molecular mechanisms by which IL-15 is able to drive NK differentiation remain poorly understood. Here we show that blocking interaction between the receptor tyrosine kinase Axl and its ligands (Gas6 and protein S) by either soluble Axl/immunoglobulin Fc fusion protein (Axl-Fc) or warfarin, a vitamin K inhibitor, diminished the number and percentage of CD3−CD56+ NK cells di
