Single-cell RNA sequencing maps cell populations in the rat brain, revealing electroacupuncture's effects on drug delivery in central nervous system disorders.
Background: The blood-brain barrier (BBB) interferes with the treatment of central nervous system disorders owing to the complexity of its structure and restrictive function. Thus, it is challenging to develop central nervous system drug delivery strategies. Specific mode electroacupuncture (EA) stimulation can effectively open the BBB in rats. Methods: Here, we used single-cell RNA sequencing (scRNA-seq) to comprehensively map the cell population in the rat cerebral cortex. Results: We identified 23 cell subsets and eight types of cells in the brain by cell annotation. scRNA-seq revealed transcriptional changes in the cerebral cortex under EA. Conclusions: Our findings offer valuable insights into the molecular and cellular modifications in the brain resulting from EA intervention and serve as a resource for drug delivery across healthy and diseased states. Innovative approaches to enhance BBB opening will lead to more effective therapeutic plans and enhanced drug delivery.
