Antroquinonol Exerts Immunosuppressive Effect on CD8⁺ T Cell Proliferation and Activation to Resist Depigmentation Induced by H₂O₂

Figure 4

Antroquinonol counteracted inhibition of HF length and skin thickness induced by H₂O₂. (a) H&E staining was performed on skin samples harvested after 50 days. HF length and skin thickness were measured. The black dotted line represented the HF. The area within the blue dotted line represents the skin thickness. The black arrows indicated the hair shaft. Scale bar = 100 μm. (b) HF length is presented as the mean length of all photomicrographs ± SD. (c) Dorsal skin thickness is presented as the mean thickness of all photomicrographs ± SD (). means statistical difference.
