Of those, notably in the experimental and clinical sepsis-associated SIRS, cytokines (e.g., tumor necrosis factor (TNF), interleukin (IL)-1α, IL-1β, and IL-6), chemokines, growth factors, adhesion molecules, gaseous substances, vasoactive peptides, and cell stress markers have been identified and analyzed [33]. This evidence concerns the gene IL6 and systemic inflammatory response syndrome.
