In Australia, when you ask for a Thyroid hormone test, they don't actually test for your thyroid hormones. They test for Thyroid stimulating hormones (TSH), and only if these are outside of normal, do they actually test for the thyroid hormones themselves.lyndacarol wrote:It should be the first suspect. And the first levels tested. Mine were tested and found to be normal.
Thyroid hormone activates oligodendrocyte precursors and increases a myelin-forming protein and NGF content in the spinal cord during experimental allergic encephalomyelitis
Remyelination in the adult central nervous system has been demonstrated in different experimental models of demyelinating diseases. However, there is no clear evidence that remyelination occurs in multiple sclerosis, the most diffuse demyelinating disease. In this article, we explore the possibility of promoting myelination in experimental allergic encephalomyelitis, a widely used experimental model of multiple sclerosis, by recruiting progenitors and channeling them into oligodendroglial lineage through administration of thyroid hormone (T4). A large number of proliferating cells (BrdUrd uptake and Ki67-IR) and the expression of markers for undifferentiated precursors (nestin) increased in the subventricular zone and spinal cord of experimental allergic encephalomyelitis animals. T4 administration reduces proliferation and nestin-immunoreactivity and up-regulates expression of markers for oligodendrocyte progenitors [polysialylated-neural cell adhesion molecule (PSA-NCAM), O4, A2B5] and mature oligodendrocytes (myelin basic protein) in the spinal cord, olfactory bulb, and subventricular zone.
