Term
IL-1
Definition
Secreted by macrophages.
Fever, acute inflammation, adhesion molecule expression in endothelium, chemokine secretion to recruit leukocytes
Term
IL-6
Definition
Secreted by macrophages and TH cells.
Fever, stimulates production of acute-phase proteins.
Term
IL-8
Definition
Secreted by macrophages.
Major chemotactic factor for neutrophils
Term
IL-12
Definition
Secreted by macrophages and B cells.
Induces differentiation of T cells into TH1, activates NK cells.
Term
TNF-alpha
Definition
Secreted by macrophages.
Mediates septic shock, activates endothelium, causes leukocyte recruitment and vascular leak
Term
IL-3
Definition
Secreted by all T cells
Supports growth and differentiation of bone marrow stem cells
Term
IL-2
Definition
Secreted by TH1 cells.
Stimulates growth of helper and cytotoxic T cells
Term
IFN-gamma
Definition
Secreted by TH1 cells
Activates macrophages and TH1 cells, suppresses TH2 cells, has antiviral and antitumor properties, increases MHC I and II expression on APCs
Term
IL-4
Definition
Secreted by TH2 cells.
Induces differentiation into TH2, promotes growth of B cells, enhances class switching to IgE and IgG
Term
IL-5
Definition
Secreted by TH2 cells
Promotes differentiation of B cells, enhances class switch to IgA, stimulates growth and differentiation of eosinophils
Term
IL-10
Definition
Secreted by TH2 cells and Tregs.
Modulates inflammatory response (similar to TNF-alpha), inhibits actions of activates T cells and TH1, activates TH2
Term
IFN-alpha
Definition
Inhibits viral protein synthesis, activates NK cells
Term
IFN-beta
Definition
Inhibits viral protein synthesis, activates NK cells
