This study investigated thalamic metabolic alterations related to acute and chronic inflammation in mice infected with TMEV, a model of MS. TMEV-inoculation causes a biphasic neurological disease starting with an early acute inflammation of the subcortical gray matter (<1 month) and progressing into a late chronic demyelinating phase associated with oligodendroglial damage that develops into a neurodegenerative phase (>4 months).

Our hypothesis was that the influx of immune cells will result in increased glutamate and myoinositol in the acute phase, and that glutamate will further increase in the chronic phase whereas gamma-aminobutyric acid, N-acetylaspartate, and choline will decrease.
