    ..The implications of the differential effect of acute versus permanent Hsp70 overexpression for tumor therapy are discussed. ..

    ..In conclusion, these results strongly argue against an Mpr300- or Mpr46-dependent pathway of granzyme-mediated killing and provide new insight in the internalization of monomeric and complexed granzyme B. ..

    ..The reduced cell surface expression of NKG2D in response to engagement by MICA-129Met variants appeared to reduce the severity of aGVHD. ..

    ..If expressed at the cell surface, the MICA-129Met isoform was more susceptible to shedding. Both processes appear to limit the cell surface expression of MICA-129Met variants that have a high binding avidity to NKG2D. ..
  5. Dressel R. Effects of histocompatibility and host immune responses on the tumorigenicity of pluripotent stem cells. Semin Immunopathol. 2011;33:573-91 pubmed publisher
    ..This has to be considered when the results of experimental transplantation models are interpreted and even more when translation into clinics is planned. ..

    ..Interestingly, the differentiated cells must contain a tumorigenic cell population that is not present among ES cells and which might be resistant to NK cell-mediated killing. ..

Multipotent adult germ-line stem cells, like other pluripotent stem cells, can be killed by cytotoxic T lymphocytes despite low expression of major histocompatibility complex class I molecules.

    ..However, a deficiency can apparently be compensated and affects only transiently the cytotoxic activity of CTL during their development to armed effector cells. ..

    ..Thus, T helper cells with specificity for an antigen in cardiomyocytes can directly promote the progression of heart failure in response to pressure overload independently of autoantibodies. ..

    ..In agreement with a postulated function of Mpr300 as a tumor suppressor gene, deficiency of Mpr300 appears to promote cellular proliferation and tumorigenicity but not resistance to allorejection. ..
