Topic : the significance of Th1/Th2 responses to clinical outcomes.

Briefly summarize the key characteristics of Th1 and Th2 cells: What cytokines do these cells produce? What types of resulting effector functions predominate?
Describe one infectious disease or an autoimmune disease described for either animal models or humans, for which the Th1/Th2 response characteristics have been studied. (e.g. Leishmania in mice; leprosy in humans). What conclusions have been drawn from this study?
Why do you think it is important to understand these responses? For example, what impact might this information have on drug and vaccine development? Explain your thinking.
At the end of your report include an open-ended and provocative question that will inspire your classmates to respond to your report.
