  A search for high-energy neutrinos coming from the direction of the Sun has
been performed using the data recorded by the ANTARES neutrino telescope during
2007 and 2008. The neutrino selection criteria have been chosen to maximize the
selection of possible signals produced by the self-annihilation of weakly
interacting massive particles accumulated in the centre of the Sun with respect
to the atmospheric background. After data unblinding, the number of neutrinos
observed towards the Sun was found to be compatible with background
expectations. The $90\%$ CL upper limits in terms of spin-dependent and
spin-independent WIMP-proton cross-sections are derived and compared to
predictions of two supersymmetric models, CMSSM and MSSM-7. The ANTARES limits
are competitive with those obtained by other neutrino observatories and are
more stringent than those obtained by direct search experiments for the
spin-dependent WIMP-proton cross-section.
