Rule #3: Use Text as Reference
A sample page taken from the Study Guide is shown below.
We will begin looking at the biology of AIDS by looking at the target
of HIV, the immune system.
Brief Overview Reading:
- pages 856 - 862
''The immune...""; stop at ''T-dependent...''
figures 39.10 and 39.11
- pages 864 - 870
''How...''; stop at ''Complement...'' including methods box
- pages 873 - 875
''Immunodeficiency'' to the end of the chapter
Rule #4: Provide Study Questions
1. What does the immune system do and, in general, how does it do it?
2. Which arm of the immune system is more effective against protein
and bacterial antigens? Which arm is more effective against viruses and
3. How do viruses target specific cells? From an evolutinary perspective,
explain why a cell would have a viral target (receptor) in its plasma membrane
if this molecule allows the cell to be infected and killed.
4. Which cell of the immune system is the primary target for HIV? What
role does this cell play in immunity?
5. What is CD4 and what does it do in a healthy immune system? How is
this molecule related to HIV?
