A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The intracellular signals that trigger natural cytotoxicity have not been clearly determined. The Syk and ZAP-70 tyrosine kinases are essential for cellular activation initiated by B and T cell antigen receptors and may drive natural killer (NK) cell cytotoxicity via receptors bearing immunoreceptor tyrosine-based activation motifs (ITAMs). However, we found that, unlike B and T cells, NK cells developed in Syk-/-ZAP-70-/- mice and, despite their nonfunctional ITAMs, lysed various tumor targets in vitro and eliminated tumor cells in vivo, including those without NKG2D ligands. The simultaneous inhibition of phosphatidyl inositol 3 kinase and Src kinases abrogated the cytolytic activity of Syk-/-ZAP-70-/- NK cells and strongly reduced that of wild-type NK cells. This suggests that distinct and redundant signaling pathways act synergistically to trigger natural cytotoxicity.
