Cytokine profiling of plasma (represented by Bd) and bronchoalveolar lavage (BAL) fluid from sepsis patient samples. Cytokine assessment was performed on plasma or BAL fluid samples which were collected within 48 h of clinical classification of severe sepsis and ICU admission. IFN-γ, IL-2, IL-4, IL-6, and TNF-α levels are represented as pg/mL in mean ± SEM, with all data from individual controls or patients. Statistical analysis was performed using the Mann-Whitney test, where ** p < 0.01, or *** p < 0.001 were considered for statistical significance.
