Examples of intracytoplasmic expression of TNF-α and IFN-γ in CD3⁺BM MNCs from 2 representative FA patients (UPN 1 and 7) and 2 representative healthy control subjects. As shown in Table 2 and Figure 2, TNF-α and IFN-γ were also expressed in CD3^– cells. In the top right corner of each scattergram the percentage of positive BM cells is represented. UPN 1: (A) CD3⁺/TNF-α⁺ cells, 7%; (B) CD3⁺/IFN-γ⁺ cells, 9%. UPN 7: (C) CD3⁺/TNF-α⁺ cells, 17%; (D) CD3⁺/IFN-γ⁺ cells, 20%. Healthy control 1: (E) CD3⁺/TNF-α⁺ cells, less than 1%; (F) CD3⁺/IFN-γ⁺ cells, 2%. Healthy control 2: (G) CD3⁺/TNF-α⁺ cells, less than 1%; (H) CD3⁺/IFN-γ⁺ cells, less than 1%.
