Vanadium inhalation induces retinal Müller glial cell (MGC) alterations in a murine model.

Changes in glial fibrillary acidic protein expression induced by V suggest retinal damage, whereas glutamine synthetase gradual reduction might indicate that photoreceptors, which produce most of the glutamine synthetase substrate in the retina, are degenerating, probably as a consequence of the oxidative stress induced by V.
