Expression of tumor necrosis factor-alpha receptors on bovine macrophages, lymphocytes and polymorphonuclear leukocytes, internalization of receptor-bound ligand, and some functional effects.

The expression of TNF-receptors appeared to be regulated by other cytokines such as IFN-gamma and IL-2, with IFN-gamma down-regulating receptor expression on all cell types, and IL-2 up-regulating receptor expression on lymphocytes
