\n The non-interacting topological insulators (TIs) have attracted great interest in the last decade. While this class of materials is today well-understoo d\, the effect of electron-eletron interactions in such systems remains in general elusive. In this talk\, I will address two different aspects of i nteractions in 2D topological band structures: (i) in some cases\, strongl y interacting TI models can be used to describe the exotic magnetic proper ties of certain transition metal oxides. (ii) in other cases\, strong inte ractions can drive a TI into spin-liquid phases.
