Unraveling the Story of NGF-mediated Sensitization of Nociceptive Sensory Neurons: ON or OFF the Trks?
Nerve Growth Factor (NGF) is produced by and affects a number of immune and inflammatory cells. As part of the inflammatory response, NGF directly or indirectly alters the sensitivity of small diameter sensory neurons that communicate noxious information. The question remains as to the receptors and...

Summary: | Nerve Growth Factor (NGF) is produced by and affects a number of immune and inflammatory cells. As part of the inflammatory
response, NGF directly or indirectly alters the sensitivity of small diameter sensory neurons that communicate noxious information.
The question remains as to the receptors and intracellular signaling cascades that mediate this sensitizing action of NGF.
Although the general consensus is that NGF produces peripheral sensitization by activating TrkA, recent work suggests that
p75 also contributes. Thus, both NGF receptors appear to contribute to peripheral sensitization although whether they act
independently or together remains to be determined. Furthermore, controversy exists as to the downstream signaling pathways
involved in NGF-induced peripheral sensitization. |
