Leukemia inhibitory factor (LIF), ciliary neurotrophic factor (CNTF), and related proteins are potentially involved in several aspects of sensory neuron development. There is evidence that LIF promotes the differentiation of sensory neurons from progenitor cells of neural crest origin. Later in development, LIF, CNTF, oncostatin M and interleukin-6 promote the survival of cultured neurons. Some neurons, like those of the nodose ganglion, respond early in their development to these factors, whereas other neurons, like those of the trigeminal ganglion, respond much later. In addition to promoting sensory neuron survival, there is some evidence that LIF is able to influence neurotransmitter and neuropeptide expression in these neurons. These observations suggest that several kinds of sensory neurons may be influenced in various ways by LIF and related factors at different stages of their development. |
