L-Theanine Mitigates Aβ1-42-Induced Apoptosis in SH-SY5Y Cells.

ABSTRACT: Alzheimer's disease (AD) is a neurodegenerative disorder that significantly impacts the physical and mental health of elderly individuals. Previous research has demonstrated a close association between neurodegenerative diseases and neuronal apoptosis, with cognitive disorders such as AD often exhibiting pathological features, including neuronal apoptosis. In recent years, the application of natural plant molecules for the prevention of AD has emerged as a focal point in food nutrition research. L-theanine, a unique active compound found in tea, has been shown to possess neuroprotective properties, although its underlying mechanisms remain to be fully elucidated. This study established an in vitro model of AD using SH-SY5Y cells induced by Amyloid-beta (1-42) (Aβ1-42) to investigate whethe
