  13. Developmental Pathobiology of Lymphocyte Fcy Receptors
    Richard Lynch; Fiscal Year: 2003
    ..Recent findings suggest that FcgRlll (CD16), an ITAM-containing protein kinase-activation receptor, and FcgRll (CD32), an ITIM-containing protein kinase-inhibitory receptor, mediate positive and negative lymphopoietic signals, ..
  14. NOVEL CD32 ISOFORMS MODULATE NK CELL FUNCTIONS
    PENELOPE MOREL; Fiscal Year: 2003
    ..These studies are of potential significance because NK cells have not been previously shown to express CD32 and thus this potentially represents a new means of activating and/or regulating NK cell lysis...
