Problems solved by technology

However, the long-term application of hormone drugs and immunosuppressive drugs can easily lead to low immune function, such as Cushing's syndrome, and even serious side effects such as infection and tumor
Therefore, autoimmune diseases currently lack effective means of prevention and / or treatment
