Abstract Cirrhosis is a chronic liver disease. The present work aimed to evaluate the regulatory immune effect of curcumin in hepatic cirrhosis induced by carbon tetrachloride (CCl4) injections in experimental rats’ model. Chronic liver fibrosis was induced in experiment animals by recurrent injections of CCl4 for more than 5 weeks. They were divided into five groups: first group was injected with normal saline, second group with CCl4, third, fourth, and fifth groups were injected with CCl4 (intraperitoneal injection) at dose 3 ml/kg, two times weekly for 6 weeks supplemented with the administration of curcumin with concentrations 250, 200, and 150 mg/kg. Immune response was analyzed to different treatments. Interleukin 10 (IL‐10), pro‐inflammatory cytokines TNF‐α, TGF‐1β, and liver histopathological examinations were conducted. The results showed that estimations of IL‐10 concentrations were significantly increased in curcumin groups compared with CCl4 group, whereas TNF‐α and TGF‐1β levels were significantly decreased comparing with CCl4 group. The histopathological examinations for liver tissues showed that curcumin treated groups have almost retained the normal structure of liver tissues. In conclusion, curcumin inhibited hepatic fibrosis and liver fibrogenesis with regulation of the immune system mechanism against invader chemical toxicity. Practical applications Curcumin is well documented for its medicinal properties, commonly used as a spice. Our work has thus demonstrated its effectiveness as an immunomodulatory agent. Practically, clinical studies have suggested that curcumin displays a diverse and powerful array of pharmacological effects in nearly all of the human body's major organ systems. These are: antidiabetes, anti‐inflammatory, anticancer, antiaging, antioxidant, antibacterial infection, hepatoprotective, neurodegenerative, and cardiovascular effects.
