Candidates were subject to further analysis for protective effects
Out of the 249 substance tested, the scientists found 35 potential drugs that could protect nerves from iron damage. They then analyzed these substances for additional therapeutic properties. They looked at whether or not they protected mitochondria, which is the powerhouse that provides energy for each cell. They also looked at whether any of the drugs helped reduce the activity of white blood cells. These immune cells are the culprits in multiple sclerosis, responsible for damaging nerve cells by attacking their protective insulation.
