Interleukins d
Name Source Function
IL-12 macrophages NK cell stimulation, Th1 cells induction. May suppress food allergies
IL-13 TH2-cellsStimulates growth and differentiation of B-Cells (IgE), inhibits TH1-cells and
the production of macrophage inflammatory cytokines
IL-14T cells and certain malignant
B cellscontrols the growth and proliferation of B cells
IL-15
mononuclear phagocytes
(and some other cells)
following infection by
virus(es).
Induces production of Natural Killer Cells
IL-16
a variety of cells (including
lymphocytes and some
epithelial cells)
Chemoattracts immune cells expressing the cell surface molecules CD4
IL-17 - Induces production of inflammatory cytokines
IL-18 macrophages Induces production of Interferon-gamma (IFNγ)
IL-20 - regulates proliferation and differentiation of keratinocytes
IL-21 - Induces proliferation in natural killer cells (NK) and cytotoxic T cells
IL-22 -
Activates STAT1 and STAT3 and increases production of acute phase
proteins such as serum amyloid A, Alpha 1-antichymotrypsin and
haptoglobin in hepatoma cell lines
IL-23 - Increases angiogenesis but reduces CD8 T-cell infiltration

Interleukins d
Name Source Action
IL-24 -Plays important roles in tumor suppression, wound healing and
psoriasis by influencing cell survival.
IL-25 -Induces the production IL-4, IL-5 and IL-13, which stimulate eosinophil
expansion
IL-26 -Enhances secretion of IL-10 and IL-8 and cell surface expression of
CD54 on epithelial cells
IL-27 - Regulates the activity of B lymphocyte and T lymphocytes
IL-28 - Plays a role in immune defense against viruses
IL-29 - Plays a role in host defenses against microbes
IL-30 - Forms one chain of IL-27
IL-31 - May play a role in inflammation of the skin
IL-32 -Induces monocytes and macrophages to secrete TNF-α, IL-8 and
CXCL2
IL-33 - Induces helper T cells to produce type 2 cytokines
