Background
Leukemia Inhibitory Factor has been shown to possess a remarkable variety of actions. It releases calcium from bone tissue, and is the differentiation inhibitory factor preventing spontaneous differentiation in normal embryonic stem cells[1]. Leukemia inhibitory factor (LIF) is a neuropoietic cytokine involved in both the neural and immune responses to injury. Its levels are increased in a variety of animal and human inflammatory conditions. Administration of Leukemia Inhibitory Factor can suppress inflammatory signs in some cases, for instance after intratracheal lipopolysaccharide-induced inflammation. Leukemia Inhibitory Factor also increases corticosterone levels via the hypothalamo-pituitary-adrenal axis. Other evidence suggests, that it can also act as a proinflammatory cytokine. Exogenously added Leukemia Inhibitory Factor induces acute phase protein expression and stimulates the production of proinflammatory cytokines and monocyte chemoattractants[2].
