Fig. 4From: Coevolutionary feedback elevates constitutive immune defence: a protein network modelEffector activity. Constitutive and induced effector activity under (a) low and (b) high parasite encounter probability (0.2 and 1.0, respectively) and three different host-parasite coevolutionary scenarios: no parasite coevolution (Scenario 1: non-specific detection and elimination; top row), parasite coevolution against the host effector (Scenario 2: non-specific detection and specific elimination; middle row), and parasite coevolution against the host receptor (Scenario 3: specific detection and non-specific elimination; bottom row). The effector for which the activity level is shown is highlighted in yellow. Fixed parameter values are as given in Fig. 3 captionBack to article page
