Cytokine family divided into functional families based of inflammatory nature of cytokine.

Pro-inflammatory:	IL-1β IL-7 IL-8 IL-12 IL-15 IL-17 IL-18 IL-23 IL-33 IL-34 G-CSF TNF- α TNF- β IFN- γ
Anti-inflammatory:	IL-4 IL-5 IL-10 IL-13 IL-22 IL-27 IL-35 IL-37 (IL-1F7) IL-38 (IL-1F10) TGF-β
Variable:	IL-6 * IL-11 * IFN-α * IFN- β *

Abbreviations: IL; interleukin, IFN; interleukin, G-CSF; granulocyte colony stimulating factor, TNF; tumour necrosis factor, TGF; transforming growth factor. * Have contrasting mechanisms suggesting that the cytokine may be involved in both pro- and anti-inflammatory activities [69,70,71,72].
