CD14 and CD16 expressing monocytes in the thyroid tissues of patients with Graves’ disease. Immunofluorescence staining was carried out using the samples of the normal thyroid tissues of patients with thyroid nodules (a–d) and patients with Graves’ disease (e–h). The scale was 100 μm. Cells that co-express CD14 (green) and CD16 (red) markers in a similar ___location were yellow in color. The frequency of CD14+ , CD16+ and CD14+ CD16+ cells were calculated per high power field (HPF, × 400) in multiple samples: NC (n = 3, 15 sections) and GD (n = 6, 30 sections) were shown in (i–k), respectively; **P < 0.001.
