Tri-chloromethyl radicals produced from CCl4 metabolism initiate reactions that cause liver steatosis, fibrosis or cirrhosis [9] via the activation of cytokines such as interleukin (IL)-1, tumor necrosis factor (TNF)-α, and transforming growth factor (TGF)-β expression, and the inhibition of nitric oxide (NO) formation [10–12]. Here, TNF is linked to fibrosis.
