Parasites infect us all the time. They live in our bodies and in our cells. The brain can provide a perfect environment for parasites because it has structures that prevent many of the immune system’s cells from entering. Millions of people worldwide are infected. Find a brain parasite to report on and write 10 sentences about what it is, where...
5. Explain why direct antigen activation of CTLs and B cells is more important than APC-initiated activa- tion in subsequent encounters with a microbe. Why is the APC-initiated pathway needed at all? 6. There are many interactions between the innate and adaptive defense systems. List as many of them as you can and explain how they work. Why are these...
