Recent studies show that increased levels of the inflammatory cytokines interleukin-l (IL-1), interleukin-6 (IL-6), interleukin 10 (IL-10), interleukin 13 (IL- 13), interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α) and immune suppression of CD3 and CD4 T-cells and natural killer (NK) cells are related to pulmonary edema [50]. This evidence concerns the gene TNF and pulmonary edema.
