Abstract:

Changes of epidermal inflammation caused by Propionibacterium acnesP.acnes) were detected by Two-Photon Excitation Fluorescence (TPEF) imaging technology and other methods. P.acnes in the logarithmic growth phase were injected into the ears of mice, and the changes in epidermal thickness, stratum granulosum, stratum spinosum and stratum basale cells were studied by TPEF imaging technology. Thickness of ear and epidermis were detected by ear thickness measurement and HE staining method. TPEF imaging technology found that the epidermis thickness was increased significantly, the molecules in granular cells were rearranged, and the morphology of stratum spinosum and stratum basale cells was changed after P.acnes infection. Ear thickness measurement and HE staining revealed that the ear and epidermis infected by P.acnes became thicker.

Key words: two-photon imaging technology, Propionibacterium acnes, acne, epidermis, inflammation
