Abstract EN
The purpose of this study was to investigate the effect of photothermal treatment (PTT) with gold nanoshell (ANS) using a macrophage-mediated delivery system in a head and neck squamous cell carcinoma (HNSCC) cell line.
To achieve this, ANS-loaded rat macrophages (ANS-MAs) were prepared via the coculture method with ANS.
The human HNSCC (FaDu cell) and macrophage (rat macrophage; NR8383 cell) hybrid spheroid models were generated by the centrifugation method to determine the possibility of using ANS-MAs as a cancer therapy.
These ANS-MAs were set into the tumor and macrophage hybrid spheroid model to measure PTT efficacy.
Kinetic analysis of the spheroid growth pattern revealed that this PTT process caused a decreasing pattern in the volume of the hybrid model containing ANS-MAs (p<0.001).
Comparison with empty macrophages showed harmony between ANS and laser irradiation for the generation of PTT.
An annexin V/dead cell marker assay indicated that the PTT-treated hybrid model induced increasing apoptosis and dead cells.
Further studies on the toxicity of ANS-MAs are needed to reveal whether it can be considered biocompatible.
In summary, the ANS was prepared with a macrophage as the delivery method and protective carrier.
The ANS was successfully localized to the macrophages, and their photoabsorption property was stationary.
This strategy showed significant growth inhibition of the tumor and macrophage spheroid model under NIR laser irradiation.
In vivo toxicology results suggest that ANS-MA is a promising candidate for a biocompatible strategy to overcome the limitations of fabricated nanomaterials.
This ANS-MA delivery and PTT strategy may potentially lead to improvements in the quality of life of patients with HNSCC by providing a biocompatible, minimally invasive modality for cancer treatment.
