FcRIIIa (CD16) is a low-affinity Fc receptor of IgG. As the idio-binding receptor of IgG Fc, it plays an important role in the antibody-dependent cellular cytotoxicity of natural killer cells. The aim of the present study was to investigate the distribution of Kupffer cells (KCs) and the expression of their surface receptor FcRIIIa in hepatocellular carcinoma. Furthermore, we also aimed to observe the functional mechanism of FcRIIIa. Immunohistochemical analysis was employed to study KCs and FcRIIIa. In order to explore the role of FcRIIIa in the growth of cancer cells, KCs and H22 tumor cells were co-cultured in different serum. The mRNA expression levels of tumor necrosis factor (TNF)- and FcRIIIa were analyzed by RT-qPCR; the TNF- and FcRIIIa protein expression levels were examined by enzyme-linked immunosorbent assay and western blot analysis, respectively. Our results showed that the number of Kuppfer cells in cancerous tissues (21.6 +/- 7.8) was lower than those in para-cancerous (68.8 +/- 9.1) tissues and adjacent normal hepatic tissues (62.0 +/- 1.9) (P
