Terahertz wave alleviates comorbidity anxiety in pain by reducing the binding capacity of nanostructured glutamate molecules to GluA2

Research, Journal Year: 2024, Volume and Issue: 7

Published: Jan. 1, 2024

Comorbid anxiety in chronic pain is clinically common, with a comorbidity rate of over 50%. The main treatments are based on pharmacological, interventional, and implantable approaches, which have limited efficacy carry risk side effects. Here, we report terahertz (THz, 10 12 Hz) wave stimulation (THS) technique, exerts nonthermal, long-term modulatory effects neuronal activity by reducing the binding between nano-sized glutamate molecules GluA2, leading to relief comorbid anxiety-like behaviors mice. In mice co-occurring induced complete Freund’s adjuvant (CFA) injection, hyperactivity was observed glutamatergic neurons anterior cingulate cortex (ACC Glu ). Using whole-cell recording ACC slices, demonstrated that THS (34 THz) effectively inhibited excitability . Moreover, molecular dynamics simulations showed reduced number hydrogen bonds bound GluA2. Furthermore, target CFA-treatment suppressed and, as result, alleviated behaviors. Consistently, inhibition chemogenetics mimics THS-induced antinociceptive antianxiety behavior. Together, our study provides evidence for an intervention technique modulating viable clinical treatment strategy anxiety.

Frequency screening experiments show 34.5 THz stimulation could promote neurite elongation postsynaptic density protein 95 (PSD95) expression by 26.0% rat hippocampal neurons. Subsequent reveal an upregulation cyclic adenosine monophosphate (cAMP) signaling pathway adenylyl cyclase type 1 (AC1) activity after irradiation. Molecular dynamics simulations suggest photons binding between AC1 ligand, accelerating cAMP generation. vivo further confirm increase levels dendritic spine stimulation, accompanied significant improvement performance. Overall, our results as effective specific method neuromodulation, promising future applications treatment dysfunction.
