LIF

leukemia inhibitory factor

Leukaemia inhibitory factor is a cytokine that induces macrophage differentiation. Neurotransmitters and neuropeptides, well known for their role in the communication between neurons, are also capable of activating monocytes and macrophages and inducing chemotaxis in immune cells. LIF signals through different receptors and transcription factors. LIF in conjunction with BMP2 acts in synergy on primary fetal neural progenitor cells to induce astrocytes.
