Immunology and Evolution

[Eric MERLE]

Hi,
I am currently an international exchange student from France at Boston 
College (MA). For my Immunology class, I would like to write a paper on  
different forms of Immune Systems throughout evolution, and therefore 
how it evolved. This is just a small paper, but I need to base it on 
published articles and research materials. I realy would appreciate it 
if anyone could help me find some reference on that subject.
Thanking you all in advance for having taken the time to read my message 
and maybe answering me.
