CYTOKINE |
CELL
SOURCE |
CELL
TARGET |
MAIN
ACTIONS |
IL-1 |
Monocytes/macrophages,
B cells, fibroblasts, endothelial cells, some epithelial
cells |
All
cells |
•
Expression of adhesion molecules •
Emigration of neutrophils and macrophages •
Role in fever and shock •
Hepatic production of acute phase protein |
IL-6 |
Same
as for IL-1 |
T
and B cells, Epithelial
cells, hepatocytes, Monocytes/macrophages |
•
Hepatic production of acute phase protein •
Differentiation and growth of T and B cells |
IL-8 |
Monocytes/macrophages,
T cells, neutrophils,
fibroblasts, endothelial cells,
epithelial cells |
Neutrophils,
basophils, T cells, monocytes/macrophages, endothelial
cells |
•
Induces migration of neutrophils, macrophages and T
cells •
Stimulates release of histamine from basophils •
Stimulates angiogenesis |
IL-12 |
Macrophages,
dendritic cells, neutrophils |
T
cells, NK cells |
•
Induces formation of T helper cells and killer cells •
Promotes CTL cytolytic activity •
Increases production of IFN-g •
Decreases production of IL-17 |
IL-17 |
CD4+T
cells |
Fibroblasts,
endothelial cells, epithelial
cells |
•
Increases secretion of other cytokines •
Migration of neutrophils and monocytes |
TNF-α |
Monocytes/macrophages,
mast cells/ basophils,
eosinophils, B cells, T cells, NK
cells |
All
cells except RBCs |
•
Hepatic production of acute phase protein •
Systemic features (fever, shock, anorexia) •
Expression of endothelial adhesion molecules •
Enhanced leucocyte cytotoxicity •
Induction of pro-inflammatory cytokines |
IFN-
g |
T
cells, NK cells |
All
cells |
•
Activation of macrophages and NK cells •
Stimulates secretion of Igs by B cells •
Differentiation of T helper cells |
MCP-1 |
Fibroblasts,
smooth muscle cells, blood mononuclear
cells |
Monocytes/macrophages,
NK cells,
T cells |
•
Chemoattractant for monocytes, T cells and NK cells •
Stimulates release of histamine from basophils |
Eotaxin |
Alveolar
cells, myocardium |
Eosinophils,
basophils |
•
Chemoattractant for eosinophils and Basophils •
Induces allergic pulmonary disease |
PF-4 |
Platelets,
megakaryocytes |
Fibroblasts,
endothelial cells |
•
Chemoattractant for fibroblasts • Inhibitory to haematopoietic precursors and endothelial cell proliferation |
IL=interleukin;
TNF=tumour necrosis factor; IFN=interferon; MCP=monocyte chemotactic protein;
PF=platelet factor.
