ATH-1105, a small-molecule positive modulator of the neurotrophic HGF system, is neuroprotective in co-culture of human iPSC-derived motor neurons and muscle (ALS-MND 2024) - "Rat motor neurons treated with 100 nM ATH-1105 þ glutamate exhibited a 23% increase in both neuronal survival (p < 0.05) and neurite networks (p < 0.01) compared to cultures challenged with glutamate alone. These effects coincided with a 131% increase in pMET levels (p < 0.01) in cultures treated with 100 nM ATH-1105 ± glutamate versus glutamate alone. Knockdown of the MET receptor using siRNA abolished the protective effects of ATH-1105 on neuronal survival and neurite networks."
