    A single-cell proteomics study mapped protein-level differences in the developing human brain, revealing discordance with RNA expression.

  • 2

    Researchers quantified hundreds of proteins from individual prenatal brain cells using a label-free mass spectrometry workflow.

  • 3

    The study profiled over 1,500 brain-derived cells, identifying major neural and non-neural populations during development.

  • 4

    Protein abundance was found to be more cell-type-specific than mRNA levels, highlighting the role of post-transcriptional regulation.

  • 5

    The findings suggest that single-cell proteomics could clarify the impact of genetic risk on neurodevelopmental disorders.
