Among cold dark-matter candidates are low-mass neutral bosons. The existence of such pseudo-scalar particles has been proposed long ago by Peccei and Quinn to explain the spontaneous breaking of CP in the early Universe. In this talk we discuss a possible mechanism to explain for non-zero neutrino masses, which is based on the treatment of neutrino-axions interactions.From the known limits to the values of the neutrino mass, extracted from the non-observation of the neutrinoless double beta decay, we set relations between the axion-neutrino coupling, the axion mass and the neutrino mass
