Scientists have found that the immune regulation of mesenchymal stem cells has such plasticity that it is like a mediator of the inflammatory environment: when the inflammatory response strengthens, the mesenchymal stem cells will suppress the immune response; when the inflammatory response weakens, On the contrary, mesenchymal stem cells may promote an immune response. This characteristic needs to be paid great attention to the process of treating diseases. For example, scientists have found that mesenchymal stem cells entering the human body can significantly alleviate the condition of patients with liver cirrhosis and inflammation in the liver. The response was significantly reduced, and liver function indicators such as bilirubin and albumin were significantly improved. However, dexamethasone will largely offset the therapeutic effect of mesenchymal stem cells on liver cirrhosis. The reason is that when patients receive dexamethasone and In the combined treatment of mesenchymal stem cells, the inflammation in the lesion site of patients with liver cirrhosis will be reduced, leading to the weakening of the immunosuppressive effect of mesenchymal stem cells, the therapeutic effect of mesenchymal stem cells completely disappeared, and even the disease will be aggravated. According to this text, the following is true:. ['Mesenchymal stem cells are better than dexamethasone in treating liver cirrhosis.', 'Mesenchymal stem cells counteract inflammatory inhibitory effects of dexamethasone.', 'The combined use of mesenchymal stem cells and certain drugs may destroy its therapeutic effect on inflammatory diseases.', 'Scientists can shape the immune regulatory function of mesenchymal stem cells based on the characteristics of the inflammatory environment.']
