Inhibition of CCl4-induced liver inflammation and fibrosis by a NEU3 inhibitor.

ABSTRACT: Sialic acids are located on the ends of many glycoconjugates and are cleaved off by enzymes called sialidases (neuraminidases). Upregulation of neuraminidase 3 (NEU3) is associated with intestinal inflammation and colitis, neuroinflammation, and lung fibrosis. Genetic ablation of NEU3 or pharmacological inhibition of NEU3 reduces lung fibrosis in mice. To determine if inhibiting NEU3 can inhibit liver fibrosis in the commonly-used CCl4 model, in this report, we examined the effects of injections of the NEU3 inhibitor 2-acetyl pyridine (2AP). 2AP inhibited CCl4-induced weight loss in female but not male mice. 2AP attenuated CCl4-induced liver inflammation and fibrosis in male and female mice, but did not affect CCl4-induced steatosis. After CCl4 treatment, female but not male mice had signi
