Toxic products produced by macrophages
Weblipid products can activate M1 macrophages via TLR4. This low-level activation of macrophage contributes to the develop-ment of insulin resistance and glucose intolerance.6 Th2 response, the immunologic counterpart of the Th1 response, is mediated by CD4+ Th2 cells, which produce IL-4 and IL-13.7 Both IL-4 and IL-13 share ligand-binding WebTumor necrosis factor alfa is naturally produced by activated macrophages and monocytes and has pleiotropic effects on normal and malignant cells. Unfortunately, the systemic administration of tumor necrosis factor alfa as a single agent gave disappointing results with severe adverse effects and no significant clinical antitumor effect [ 1, 2 ].
