IFN-γ production in response to different fractions of C. albicans and other antigens. Whole-blood cultures from patients and controls were stimulated with different C. albicans fractions (CS, DPS, MAN) or non-Candida antigens (TT, PHA) for 48 h. Supernatants were collected, and cytokine levels were assessed by performing ELISAs. Each symbol indicates the cytokine level for an individual patient (CMC) (solid symbols) or a control (C) (open symbols). bg, background cutoff level; NS, not significant. Note the log scale.
