I want to know the answer to the following question:
What triggers an immune response according to CST?
All the background I'm provided with is that "On the basis of CST, Burnet developed a theory of how an immune response is triggered according to the self/nonself distinction: "self" constituents (constituents of the body) do not trigger destructive immune responses, while "nonself" entities (e.g., pathogens, an allograft) trigger a destructive immune response.". Is that enough to answer the question?
Answer: yes
