Histochemical and immunohistochemical characteristics of mast cells in nasal polyps.

abstract：:Endotoxin (lipopolysaccharide [LPS]) is known to induce the production of tumor necrosis factor (TNF)-alpha and the induction of manganese superoxide dismutase (MnSOD). We have recently demonstrated that induction of TNF-alpha and MnSOD by LPS is mediated through different signal transduction pathways. In the current ...
