Duplication of methyl-CpG-binding protein 2 (MECP2) gene causes MECP2 duplication syndrome (MDS). To normalize the duplicated MECP2 in MDS, we developed a high-fidelity Cas13Y (hfCas13Y) system capable of targeting the MECP2 (hfCas13Y-gMECP2) messenger RNA for degradation and reducing protein levels in the brain of humanized MECP2 transgenic mice. Moreover, the intracerebroventricular adeno-associated virus (AAV) delivery of hfCas13Y-gMECP2 in newborn or adult MDS mice restored dysregulated gene expression and improved behavior deficits.

Alzheimer's disease (AD) is a leading cause of dementia in the elderly, with no effective treatment currently available. Transcranial direct current stimulation (tDCS), a non-drug and non-invasive therapy, has been testified efficient in cognitive enhancement. This study aims to examine the effects of tDCS on brain function in a mouse model of AD.
