Target cell recognition and cytotoxicity of human CD56+ NK and LAK cells is readily inhibited by acetylated mannose. Two respective NK cell receptor candidates were isolated from human leukocyte lysates by mannose acetate affinity chromatography. The 87-kDa receptor showed sequence homologies with lactoferrin and the 59-kDa receptor represented a complex of two Ca-binding proteins MRP-8 and MRP-14 reportedly expressed only by cells of myeloid origin. The 87-kDa receptor exhibited heterogeneity in isoelectric focusing and behaved entirely differently from lactoferrin. Preincubation of tumor target cells with the 87-kDa receptor inhibited competitively target cell recognition and cytotoxicity of human CD56+ NK and LAK cells.
