Some of the light scalar and vector meson resonances can be properly described in the frame of chiral unitary models for the meson meson scattering amplitudes. Starting from this scheme, we study the most relevant mechanisms in a many body approach leading to a renormalization of the meson resonance properties in a nuclear medium. We shall emphasize on the role of the pion and kaon selfenergies, arising from their interactions with the nucleons of the medium. Some applications to the study of meson production reactions in nuclei will be addressed.
