Principal Activities
IL-1 Activated Macrophages Pyrogen (cause fever).
Activates Endothelial cells.
Stimulatory to T-Cells.
Enhances activity of NK cells.
Provides a competence signal         to allow B-Cell growth.
IL-2 Th1 & Tc cells

 

 T cell proliferation and differentiation.
Macrophages, NK, & Tc cell activation.
Th1 autocrine growth factor.
IL-4 Th2 cells B cell proliferation and differentiation,
Ig isotype switching (IgE).
Increases MHC-II on B-Cells.
