Figure 4.
Frequencies of Candida-reactive T cells in healthy donors, disease control and patients with probable or proven invasive Candida infection. Patients with proven invasive Candida infection had a simultaneous 3.05-fold increase of antigen-stimulated T cells compared to unstimulated T cells to exclude false positive results and to determine quality of the stimulation. Dashed lines show cut-off values for C. albicans-reactive T cells (0.40%) and C. glabrata-reactive T cells (0.22%), respectively. Healthy donor n = 14, disease control n = 9. (A) Frequencies of C. albicans CD69+/CD154+ T cells among CD4+ T cells in donor/patient cohorts. Given is the highest frequency during the test series. (B) Frequencies of C. glabrata CD69+/CD154+ T cells among CD4+ T cells in donor/patient cohorts. Given is the highest frequency during the test series.
