Programmable Neuronal Circuit Repair via Epigenetic CRISPR

**Background and Rationale** Neurodegeneration is characterized by the progressive loss of specific neuronal populations, leading to devastating diseases such as Parkinson's disease (PD), Huntington's disease, and amyotrophic lateral sclerosis. Traditional therapeutic approaches have focused on symptom management or neuroprotection, but these strategies fail to address the fundamental problem: the irreversible loss of specialized neuronal circuits. Recent advances in epigenetic engineering and ...
