From: Efficiency of the immunome protein interaction network increases during evolution
Characteristics of the human immunome network during evolution. (A) Efficiency (solid line) and expected efficiency calculated as a function of 1/(ln ln N) (dashed line), and 1/(ln N) (dotted line), where N is the number of nodes in the network. Expected efficiency curves are scaled to have the same starting values as the observed network. The shape of the observed efficiency curve shows an opposite trend than expected, suggesting that selective forces during evolution favor higher efficiency. (B) Maximal vulnerability.
