 Elliptical galaxies exhibit a very large dispersion of X-ray
 luminosities for given optical luminosity. X-ray bright galaxies
 posses a fairly dense ISM, and materials being lost by stars
 can either be in a global outflow or inflow subsonic motion.
 X-ray faint galaxies are instead likely to host a supersonic
 wind that effectively evacuates the galaxies of stellar mass
 loss materials. In the various cases very different thermal
 histories are expected for the grains forming in the circumstellar
 shells of mass losing stars. Our idea is to observe with ISO
 a representative sample of elliptical galaxies exhibiting
 extreme X-ray to optical luminosity ratios.
