Large-scale drug screening in iPSC-derived motor neurons from sporadic ALS patients identifies a potential combinatorial therapy
Imagine if scientists could take a small sample of your skin, turn those cells into the exact type of brain cells that are dying in ALS, and then test hundreds of potential medicines on them in a lab dish. That's essentially what this research accomplished. Scientists took skin cells from 100 people with ALS, converted them into motor neurons (the brain cells that control muscle movement), and discovered that these lab-grown neurons died in the same way as they do in actual ALS patients. When they tested over 100 drugs that had failed in human trials, 97% also failed in their lab model - proving their system works like the real disease. Most importantly, they found a combination of three drugs that kept the neurons alive longer, offering new hope for treatment.
