Danger

Today was the last day for the Annual Spring Meeting here in Cologne. The topic this year was "Evolution on Immunity and Pathogens". The two most exciting talks for me were from Max D. Cooper who presented an exciting model of adaptive immunity in agnatha which is quite distince from that in the gnathostomata. The other exciting talk was an overhead talk (as is typical) by Polly Matzinger discussing her Danger Model of Immunity and her adamant debunkment of traditional views into immunology.
