The infiltration status of macrophages and Treg cells in mouse skin tissues from the NC, MC and PBMT groups, as observed by immunofluorescence staining. (A) The infiltration status of γδ T cells marked by CD3 (red fluorescence) and TCRγδ (green fluorescence). Scale bar =100 µm. (B) The infiltration status of macrophages as determined by CD80 (green fluorescence) and F4/80 (red fluorescence) staining. Scale bar =100 µm. MC, model control; PBMT, photobiomodulation therapy; NC, negative control; Treg, regulatory T cell.
