Characterization of two different forms of mitogen-activated protein kinase kinase induced in polymorphonuclear leukocytes following stimulation by N-formylmethionyl-leucyl-phenylalanine or granulocyte-macrophage colony-stimulating factor.

Abstract

Incubation of polymorphonuclear leukocytes with chemoattractants, granulocyte-macrophage colony-stimulating factor (GM-CSF), or phorbol 12-myristate 13-acetate (PMA) activated both mitogen-activated protein kinase kinase (MAPKK) and mitogen-activated protein kinase (MAPK). Activation by chemoattractants was rapid and transient, being maximal by 1 min and… (More)
