Also known as Lou Gehrig\u2019s disease, ALS is notoriously difficult to treat because the brain has a \u201cgatekeeper\u201d called the blood-brain barrier. This layer of cells is great at keeping out toxins, but it\u2019s also very good at blocking the medicine doctors want to get inside.<\/p>\n
Smita Saxena, a professor at the Mizzou School of Medicine, found a clever workaround. Her team took a natural molecule called GM1 and tucked it inside a tiny bubble of fat. This microscopic package acts like a delivery truck, allowing the medicine to slip through the brain\u2019s defenses.<\/p>\n
For the Brain

To understand why this helps, you have to look at how ALS works. The disease causes a series of breakdowns in the brain that eventually lead to muscle<\/a> weakness and fatigue.<\/p>\n \u201cOur research team\u2019s previous work showed that neurons in those with ALS are very sensitive to endoplasmic reticulum stress, which limits the mitochondria\u2019s ability to produce energy,\u201d Saxena said. \u201cThis, in turn, limits the ability of neurons to send messages across synapses when we want to move our muscles.\u201d<\/p>\n Basically, the brain\u2019s power plants stop working correctly, and the messages telling your muscles to move get lost. By delivering that extra GM1 molecule, the researchers were able to help those neurons stay healthy. In tests with mice, the therapy improved their motor neurons and helped them move more easily.<\/p>\n Moving toward human trials<\/p>\n This delivery system has already been tested in humans for Parkinson\u2019s disease, where it proved to be safe. Since we already know it\u2019s well-tolerated, the team is looking toward human clinical trials for ALS.<\/p>\n If it works, the treatment could be life-changing. Researchers think it could eventually be given to younger people who carry ALS mutations, potentially stopping the disease before they ever feel a symptom.<\/p>\n
