The potential of esophageal mucosal CD3⁺, CD3⁺CD8⁺ and CD3⁺CD4⁺ T lymphocytes to produce TNF-α or IFN-γ after phorbol 12-myristate 13-acetate/ionomycin stimulation was measured using flow cytometry. Graphic representation of the absolute number of CD3⁺, CD8⁺ and CD4⁺ T cells with potential to produce TNF-α and IFN-γ. There was no difference in TNF-α and IFN-γ potential in CD3⁺CD4⁺ cells (Table 3). *P<0.05, **P<0.01.
