Figure 4: RORγt and FOXP3 protein expression in thymoma.
A, Immunohistochemical staining of RORγt and FOXP3 in each thymoma type. Positive cells showed deeply stained brown nuclei. RORγt and FOXP3 protein expression was present in all types of thymoma, but not all thymoma cases.
B, The proportion of positive staining of RORγt and FOXP3 protein The proportion of positive staining of RORγt protein in thymoma was 76.7% and 43.3% in the MG group and Tm group, respectively. The positive staining proportion of FOXP3 protein in thymoma was 53.3% and 86.7% in the MG group and Tm group, respectively.
