[Shedding of soluble intercellular adhesion molecule 1 (ICAM-1) from melanoma cells and the effect on cellular cytotoxicity].
ICAM-1-mediated cell-cell adhesion is essential for various immunologic functions, including non-MHC-restricted cytotoxicity. Shedding of ICAM-1 occurred after stimulation of melanoma cells with TNF alpha and IFN gamma. Soluble forms of ICAM-1 inhibited the conjugate formation of NK clones with K562 and of LAK cells with melanoma cells. Furthermore, the non-MHC-restricted cytotoxicity mediated by NK clones or LAK cells could be abrogated by soluble ICAM-1.
