Abstract
The effects of water-soluble chitosan oligomers (WSCO) on the synthesis of nitric oxide (NO) by murine peritoneal macrophages and on macrophage-mediated cytotoxicity towards murine fibrosarcoma Meth A cells were investigated. WSCO alone had no effect on NO synthesis and killing of tumor cells. However, treatment of macrophages with a combination of WSCO and interferon-gamma (IFN-gamma) synergically increased NO synthesis and enhanced killing of tumor cells. The synergism between IFN-gamma and WSCO in NO synthesis and tumoricidal activity was mainly dependent on increased secretion of tumor necrosis factor-alpha by WSCO.Entities:
