Q&As

What is IL2RB and what are its clinical applications?

It is an artificial protein prepared by genetic engineering techniques that can mimic the natural IL-2R beta subunit and is used to explore how to treat cancer and autoimmune diseases by regulating the IL-2 signaling pathway.

What is the effect of IL2RB in the treatment of tumor?

There has shown good therapeutic effect in the treatment of some tumors (such as lung cancer, melanoma, etc.), but the specific efficacy varies with the patient's condition, treatment timing and other factors.

What is the therapeutic mechanism of IL2RB in clinical use?

This protein can simulate the natural IL-2R beta subunit and participate in the IL-2 signaling pathway, thereby enhancing the body's immunity.

What diseases is IL2RB associated with?

IL2RB is associated with a variety of cancers (such as gastric cancer, lung cancer, liver cancer, lymphoma, etc.) and autoimmune diseases (such as rheumatoid arthritis, systemic lupus erythematosus, etc.).

Can IL2RB be an alternative to traditional treatment?

IL2RB can be used as a new therapeutic method, but it does not mean that it can replace traditional therapeutic methods. In the course of specific treatment, different treatment methods should be considered according to the condition.

Does IL2RB have side effects?

IL2RB may produce some side effects, including fever, headache, nausea, vomiting, etc., but the incidence of different side effects is low.
