THE CYTOTOXICITY PATHWAY OF NATURAL KILLER CELLS IN CORD BLOOD COMPARED TO P ERIPHERAL BLOOD
The cytotoxic activity of natural killer cells is usually tested by radioactive assay CSI Cr release assay), which detects the release of cytoplasmic contents after plasma membrane disintegration of dying cells. In contrast to this indirect evaluation of cytotoxicity, the assessment of cell damage by flow cytometry aims to provide a more exact characterization of the death pathway via detec...
متن کاملUterine natural killer cells and angiogenesis in recurrent reproductive failure.
BACKGROUND Increased numbers of phenotypically unusual CD56(bright) CD16- uterine natural killer (uNK) cells have been associated with recurrent reproductive failure. uNK cells produce angiogenic growth factors and are potential regulators of decidual angiogenesis in early pregnancy. The final common mechanism for early pregnancy loss is thought to be early onset of the maternal circulation and...
متن کاملHuman and murine inhibitory natural killer cell receptors transfer from natural killer cells to target cells.
Intercellular transfer of proteins across the immunological synapse is emerging as a common outcome of immune surveillance. We previously reported that target-cell MHC class I protein transfers onto natural killer (NK) cells expressing cognate killer Ig-like receptors (KIRs). We now show that, for both murine and human cells, target cells expressing inhibitory MHC class I ligands acquire cognat...
متن کاملInsights into the paracrine effects of uterine natural killer cells
Uterine natural killer (uNK) cells are recruited into the uterus during establishment of the implantation and placentation of the embryo, and are hypothesized to regulate uterine spiral artery remodeling and angiogenesis during the initial stages of pregnancy. Failures in uNK cell activation are linked to diseases associated with pregnancy. However, the manner in which these cells interact with...
متن کاملKilling the killer: natural killer cells to treat Ewing's sarcoma.
Cho and coworkers show that Ewing's sarcoma cells are highly sensitive to expanded allogeneic natural killer (NK) cells, partially through a NKG2D- and DNAM-1-dependent mechanism. Using an orthotopic murine model, they also show that irradiation significantly enhances the NK-cell killing of these tumors.
