Cards

Term
IL-1
Definition
Secreted by macrophages and tissue cells; α and β subunits are inflammatory cytokines that promote inflammation and the inflammatory response (fever, lethargy, anorexia, increased permeability of the vasculature) and activate lymphocytes
Term
IL-2
Definition
Secreted by dendritic cells, antigen stimulated T-cells, and NK cells; stimulates growth of CD4 and CD8 T-cells; activated T cells express high affinity for IL-2; activates B-cells and NK cells; approved for treatment of renal cell carcinoma and melanoma
Term
IL-4
Definition
Stimulates Th2 response and suppresses Th1 response; stimulates the production of IgE; stimulates the creation of memory B-cells during T-cell dependent activation
Term
IL-5
Definition
Secretion is stimulated by the TH2 response; secreted by CD4 T-cells; stimulates production of IgA; recruits eosinophils from the bone marrow and activates them; also a growth factor for basophils along with interleukin 3
Term
IL-6
Definition
Secreted by macrophages; stimulates liver to secrete CRP, MBL, and fibrinogen; induces fat and muscle cells to metabolize to increase body temperature
Term
IL-7
Definition
Produced by fibroblasts and bone marrow stromal cells; necessary for the proliferation of immature lymphoid progenitors
Term
IL-9
Definition
Secreted by TH9 cells
Term
IL-10
Definition
Stimulates B-cell maturation during T-cell dependent activation; causes the B-cell to mature into a plasma cell; no pro-inflammatory activity
Term
IL-12
Definition
Secreted by macrophages; attracts natural killer cells and causes them to proliferate and secrete IFNγ; stimulates Th1 CD4 T-cells; also secreted by dendritic cells to activate T-cells and by antigen presenting cells to activate CD8 T-cells
Term
IL-13
Definition
Stimulated by the TH2 response; secreted by basophils; induces epithelial cell repair and mucus secretion
Term
IL-15
Definition
Stimulates the survival and proliferation of memory CD4 and CD8 T cells; also secreted by macrophages when they are bound to natural killer cells answers to further activate natural killer cells in close proximity
Term
IL-17
Definition
Secreted by TH17 cells and follicular helper T cells; attracts neutrophils
Term
IL-21
Definition
Secreted by TH9 cells and differentiates some T cells into T(fh) cells
Term
IL-22
Definition
Secreted by TH17 cells and TH22 cells
Term
IL-23
Definition
Inhibits T(fh) cells and stimulates TH17 cells
Term
IL-35
Definition
Inhibitory cytokine secreted by Tregs
Term
IL-3
Definition
Growth factor for basophils
Term
CCL3
Definition
Secreted by mast cells with granules; attracts monocytes, macrophages and neutrophils
Term
CCL11
Definition
aka Eotaxin; stmulates the migration of eosinophils into tissues
Term
CCL19
Definition
Secreted by dendritic cells; attracts immature B-cells to lymph node
Term
CCL21
Definition
Secreted by stromal and dendritic cells in the T-cell area of lymph node; attracts immature B-cells
Term
IFNα
Definition
Secreted by monocytes, macrophages, B-cells, natural killer cells, and infected cells; induces an antiviral state in uninfected cells and activates natural killer cells
Term
IFNβ
Definition
Secreted by infected cells activates in case else and induces antiviral state in neighboring uninfected cells
Term
IFNγ
Definition
Secreted by T-cells and natural killer cells; activates macrophages; activates Th1 response and suppresses Th2 response; stimulates MHC Class I and II expression
Term
IGFβ
Definition
Induces production of IgG2b and IgA and inhibits production of IgM and IgG3
Term
CXCL8
Definition
A G-coupled protein secreted by macrophages that recruits neutrophils from HEVs; also increased integrin avidity
Term
CXCL13
Definition
Secreted by follicular dendritic cells
