    Description
    Recent results from PAMELA and FERMI suggest an excess in the electrons and positrons cosmic-ray spectra which have been tentatively interpreted in terms of Dark Matter annihilations or decays. I will review the required properties of Dark Matter models needed in order to explain these cosmic-ray observations and I will underline possible difficulties such models have to face with. I will then show astrophysical and cosmological constraints on these interpretations.
