The role of melatonin in affecting cognitive dysfunction in acute sleep deprivation mice through the nuclear factor kappaB pathway and oxidative stress.

ABSTRACT:

Objective

Acute sleep deprivation (ASD) is prevalent in contemporary society. This study explored the mechanism of melatonin affecting cognitive dysfunction (CD) in ASD mice through the nuclear factor kappaB (NF-κB) pathway and oxidative stress.

Methods

The ASD mouse model was established and treated with low-dose and high-dose melatonin, a NF-κB inhibitor PDTC, or lipopolysaccharide (LPS), with their spatial memory, spontaneous activity, and anxiety assessed. Hippocampal morphology and neuronal status were observed via HE and Nissl staining. Superoxide dismutase (SOD) activity and levels of hippocampal CA1 region postsynaptic density protein 95 (PSD95), phosphorylated (p)-p65, and p-IκB proteins; acetylcholinesterase (AChE), acetylcholine (ACh), malondialdehyde (MDA), and r
