Although we found that stimulated CD3+CD8+ T cells have increased IFN-γ in esophageal mucosal biopsies from EoE-New/Active (Figure 2b), IFN-γ was not detectable and not different among the study groups when we analyzed the supernatants (without stimulation) from explant tissue cultures (data not shown). The gene discussed is CD8A; the disease is eosinophilic esophagitis.
