Exposure to the Amino Acids Histidine, Lysine, and Threonine Reduces mTOR Activity and Affects Neurodevelopment in a Human Cerebral Organoid Model

The authors pioneered the use of human cerebral organoids to investigate the impact of amino acid supplementation on neurodevelopment. RNA sequencing identified gene expression changes after supplementation, with enrichment in genes related to mTOR signaling and immune function, a.o., and to specific cell types, including proliferative precursor cells, microglia, and astrocytes.
