📄 Abstract
BackgroundEpigenetic dysregulation is increasingly recognized as a key mechanism in the development and progression of Alzheimer's disease (AD). Herpes simplex virus type 1 (HSV-1) infection has been proposed as a potential biological trigger that may accelerate neurodegeneration through epigenetic modifications. Among HSV-1 structural proteins, glycoprotein B (HSV-gB) may influence host-virus interactions affecting neuronal gene regulation.ObjectiveThis study aimed to investigate the contribution of HSV-gB to AD-related epigenetic alterations and to determine whether HSV-gB exposure exacerbates epigenetic dysregulation in two in vitro neuronal AD models.MethodsHuman SH-SY5Y neuroblastoma cells were used to establish two AD models: a differentiation-based aging model induced by retinoic acid and brain-derived neurotrophic factor (RA + BDNF), and an amyloid aggregation model induced by amyloid-β 1-42 (Aβ
