Figure 2.

Plasma levels of interleukin 6 (IL-6), interleukin 23 (IL-23), and interleukin 17A (IL-17). A, Plasma was collected from patients with fungal keratitis (n = 93), cohorts (n = 15), and regional controls (n = 20), and cytokine levels were measured by enzyme-linked immunosorbent assay. Data are mean±standard error of the mean, and data points represent individuals. B, Spearman rank correlation analyses of 45 individuals (patients, cohorts, and regional controls combined) comparing the percentage of IL-17–expressing peripheral blood neutrophils with plasma levels of IL-17, IL-23, and IL-6 in each individual. C, Correlation between plasma levels of IL-17 and plasma levels of IL-6 and IL-23 (n = 121).
