Single-cell multiomics of neuron activation reveals context-specific genetics of brain disorders

Research published in Science in June 2026 examined individual neuronal cells using multiomics methods, which enable analysis of multiple biological levels simultaneously. Scientists discovered that genetic factors causing brain disorders manifest differently depending on the context of neuron activation. The study demonstrates that the same genetic variants can have different effects depending on the state and function of individual cells. These findings provide deeper understanding of how genetics influences the development of brain disorders at the single-cell level. The research suggests the need for a context-specific approach when studying genetic causes of neurological diseases.
