Query: Neutrino masses and mixing angles from leptoquark interactions   In this paper we show that the mixing between leptoquarks (LQ's) from
different $SU(2)_l$ multiplets can generate a non-trivial Majorana mass matrix
for neutrinos through one loop self energy diagrams. Such mixing can arise from
gauge invariant and renormalizable LQ-Higgs interaction terms after EW symmetry
breaking. We use the experimental indication on neutrino oscillation to find
constraints on specific combinations of LQ couplings to quark-lepton pairs and
to the SM higgs boson. These constraints are compared with the ones from
$\pi\to e\bar {\nu}_e$.
