An important component that can significantly affect the description of astrophysical and cosmological systems is dark matter, whose fundamental nature remains not fully understood. Observations indicate that approximately 27% of the Universe is composed of dark matter, 68% of dark energy (the dominant component responsible for the Universe's accelerated expansion) and only 5% of luminous matter. Recently, several studies have explored the coupling of dark matter to hadronic and/or quark models, aiming to describe astrophysical systems such as compact stars. In this talk, we present the effects of incorporating dark matter into relativistic mean-field hadronic models, as well as into a specific effective quark model in which the constituent quark masses are density-dependent functions, thus accounting for in-medium effects.
