title: Synthesis of leukemia inhibitory factor in injured peripheral nerves and their cells.
abstract: The time and site of induction of leukemia inhibitory factor mRNA in injured rat sciatic nerves and its regulation in Schwann cells and fibroblasts from neonatal rat nerves were investigated. Leukemia inhibitory factor mRNA is induced at the lesion site within 6 h of sciatic nerve transection but only after 24 h in the more distal segments. In vitro, interleukin-1beta increases the concentration of leukemia inhibitory mRNA in nerve fibroblasts but not in Schwann cells. Changes in leukemia inhibitory factor mRNA concentration in injured nerves and peripheral nerve cells are similar to those for nerve growth factor mRNA.
