Despite evidence of higher spontaneous Th1 cytokine expression in sarcoidosis CD4+ T cells, following TCR stimulation, systemic CD4+ T cells isolated from healthy controls produced significantly higher amounts of IL-2 than sarcoidosis CD4+ T cells, with an average of 2431 pg/mL compared to an average of 1220 pg/mL, respectively (Figure 1(c); p < 0.05). The gene discussed is IL2; the disease is sarcoidosis.
