It has been shown previously that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (HMG-CoA RIs) such as compactin and lovastatin suppress human lymphocyte functions in vitro (Cuthbert and Lipsky, 1981; Cutts and Bankhurst, 1989). Although it is not fully understood what inhibitory role the HMG-CoA RIs perform in causing this suppression, we show(More)
BACKGROUND In lung tumor biotherapy, local macrophages such as alveolar macrophages and tumor-associated macrophages (TAMs) which normally exist in contact with tumor cells are thought to be hopeful target. It is advantageous to clarify the potential for and mechanism by which lung tumor cells are killed by the neighboring macrophages in order to establish(More)
AIM It is possible that macrophages may be effective for cancer treatment because once activated, lung macrophages have enhanced contact with lung tumor cells and have a cytotoxic effect. In this paper, we report that nitric oxide (NO) produced by lung macrophages activated with lipopolysaccharide (LPS) suppressed cell growth of human lung adenocarcinoma(More)
