title: Deficient Candida-specific T-helper 17 response during sepsis.
abstract: Patients with sepsis in the intensive care unit (ICU) are prone to develop Candida infections. Here, we investigated Candida-induced T-helper 17 (Th17) responses during experimental human endotoxemia and in patients with sepsis admitted to the ICU. Peripheral blood mononuclear cells were stimulated with Candida albicans. The Th17 response was significantly lower during endotoxemia, compared with baseline. Patients with gram-negative sepsis had a significantly lower Th17 response as compared to healthy controls. These data demonstrate that the Th17 response is deficient during endotoxin-related systemic inflammation, which likely represents an important risk factor for increased susceptibility to develop Candida infection in patients with sepsis.
