Nerve cell trauma response. Fluorescent light micrograph of a section through a spinal cord affected by multiple sclerosis (MS). Reactive glial stem cells are producing the protein GFAP (glial fibrillary acidic protein, green) and OLIG2 (oligodendrocyte lineage transcription factor 2, red) in an attempt to repair the damaged nerve cells. Cell nuclei are dyed blue. MS is an autoimmune condition, in which the immune system attacks nerve cells, impairing their ability to relay signals efficiently.
