Mapping Molecular Discordance in the Brain
Single-cell proteomics reveals cell-type-specific regulation invisible to RNA-based methods
A groundbreaking single-cell proteomics study from the University of California, San Francisco and Stanford University has unveiled a detailed protein map of the developing human brain. This research demonstrates significant discrepancies between gene expression and protein levels, emphasizing the importance of post-transcriptional regulation in brain development. By profiling over 1,500 individual cells, the team identified key transitions, particularly from intermediate progenitors to excitatory neurons, linking them to neurodevelopmental vulnerabilities. The findings suggest novel directions for exploring genetic risk factors in neurodevelopmental disorders.
