hematopoietic system
abnormal NK cell differentiation ( J:155677 )
• in vitro cultures of Lin- bone marrow cells fail to give rise to NK 1.1 expressing cells given the appropriate cytokine stiumuli
• analysis of in vivo NK cell development by flow cytometry shows development stalled at the iNK stage (NK1.1+ DX5-)
decreased NK cell number ( J:155677 )
• in the spleen, lung, and liver
impaired natural killer cell mediated cytotoxicity ( J:155677 )
• significantly impaired cytolytic activity against Yac-1 target cells in vitro
• unable to reject transferred MHC-class I deficient cells in vivo
