From: Differential pattern and prognostic significance of CD4+, FOXP3+ and IL-17+tumor infiltrating lymphocytes in ductal and lobular breast cancers

Figure 1

Examples of CD4 + , FOXP3 + and IL-17 + infiltrating lymphocytes in ductal and lobular breast cancer. A, B, C: Immunohistochemical staining of breast cancer tissue punches incubated with anti-CD4 antibody (brown staining): A: Ductal breast cancer with predominantly stromal and intratumoral CD4+ cells. B: Ductal breast cancer with prominent cell pleomorphism and easily detectable intratumoral CD4+ cells, within the tumor and surrounding it. C: Example of an invasive lobular breast cancer with CD4+ cells. D; E: Zoom of breast cancers incubated with anti-FOXP3 antibody (brown staining): D: Invasive ductal breast cancer with clear intratumoral infiltration by FOXP3+ cells. E: Invasive lobular breast cancer with stromal and intratumoral FOXP3+ cells. F: Ductal breast cancer showing a single infiltrating IL-17+ cell (brown staining). G/H: Ductal carcinoma with a FOXP3/CD4 ratio > 1. G shows the FOXP3 staining and H the CD4 staining. I/J: Lobular cancer with a FOXP3/CD4 ratio < 1. I shows the FOXP3 staining and J the CD4 staining.
