Terahertz photons promote neuron growth and synapse formation through cAMP signaling pathway

PhotoniX, Journal Year: 2025, Volume and Issue: 6(1)

Published: April 1, 2025

Abstract Neurite outgrowth and synapse formation constitute the cellular basis for establishment plasticity of neural networks, crucially involved in cognitive functions. However, techniques currently available to effectively specifically modulate these processes remain limited. In this work, we propose a non-drug non-thermal terahertz (THz) photon modulation approach that enhances neuronal growth synaptogenesis. 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.

Achieving a high power factor and low lattice thermal conductivity is crucial for improving the thermoelectric performance. The eco-friendly Cu12Sb4S13 tetrahedrite inherently exhibits (∼10-14 μW cm-1 K-2) (0.5-1.00 W m-1 K-1), but these properties also impose significant limitations further performance enhancement. To overcome challenges, researchers have explored strategies such as codoping/synergistic element doping nanocomposites. In this work, we demonstrate that Sn at Sb site in (without use of nanocomposites) enables synergistic modulation both electronic properties. increases hole concentration enhances density states (DOS), leading to marked improvement (at 750 K), 12 K-2 x = 0 16 0.04. Simultaneously, induces strong phonon scattering, which lowers by ∼69% K).

Terahertz Wave Desensitizes Ferroptosis by Inhibiting the Binding of Ferric Ions to the Transferrin

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 3, 2025

Ferroptosis is a classic type of programmed cell death characterized by iron dependence, which closely associated with many diseases such as cancer, intestinal ischemic diseases, and nervous system diseases. Transferrin (Tf) responsible for ferric-ion delivery owing to its natural Fe3+ binding ability plays crucial role in ferroptosis. However, Tf not considered druggable target ferroptosis-associated since systemic perturbation would dramatically disrupt blood homeostasis. Here, we reported nonpharmaceutical, noninvasive, Tf-targeted electromagnetic intervention technique capable desensitizing ferroptosis directivity. First, revealed that the THz radiation had significantly decrease affinity between via molecular dynamics simulations, modulation was strongly wavelength-dependent. This result provides theoretical feasibility modulation-based intervention. Subsequent extracellular cellular chromogenic activity assays indicated field at 8.7 μm (i.e., 34.5 THz) inhibited most bound Tf, wavelength good agreement simulated one. Then, functional demonstrated levels intracellular Fe2+, lipid peroxidation, malondialdehyde (MDA) were all reduced cells treated this wave. Furthermore, deposition, MDA disease model induced ischemia-reperfusion injury could be nearly eliminated same radiation, validating wave-induced desensitization vivo. Together, work preclinical exemplar irradiation-stimulated predicts an innovative, wave-based therapeutic method future.
