  Nonlinear simulations of Alfv\'en modes (AM) driven by energetic particles
(EP) in the presence of turbulence are performed with the gyrokinetic
particle-in-cell code ORB5. The AMs carry a heat flux, and consequently they
nonlinearly modify the plasma temperature profiles. The isolated effect of this
modification on the dynamics of turbulence is studied, by means of
electrostatic simulations. We find that turbulence is reduced when the profiles
relaxed by the AM are used, with respect to the simulation where the
unperturbed profiles are used. This is an example of indirect interaction of
EPs and turbulence. First, an analytic magnetic equilibrium with circular
concentric flux surfaces is considered as a simplified example for this study.
Then, an application to an experimentally relevant case of ASDEX Upgrade is
discussed.
