Abstract: International audience ; In the present work we intend to investigate how to detectthe behaviour of the immune system reaction to an external stimulus interms of phase transitions. The immune model considered follows Jerne'sidiotypic network theory. We considered two graph complexity measures- the connectivity entropy and the approximate von Neumann entropy -and one entropy for topological spaces, the so-called persistent entropy.The simplicial complex is obtained enriching the graph structure of theweighted idiotypic network, and it is formally analyzed by persistenthomology and persistent entropy. We obtained numerical evidences thatapproximate von Neumann entropy and persistent entropy detect theactivation of the immune system. In addition, persistent entropy allowsalso to identify the antibodies involved in the immune memory.
