“…NGF does not directly interact with or stimulate GFRα receptors (38). However, in addition to direct sensitization of nociceptors, NGF also acts indirectly through activation of various peripheral cell types and the subsequent release of a host of inflammatory mediators, which in turn, sensitize sensory afferents (12,(39)(40)(41). Several inflammatory conditions stimulate artemin release from a number of peripheral cell types, including keratinocytes, fibroblasts, and immune cells (28,42,43), and we hypothesized that NGF-induced cold allodynia was mediated by NGF indirectly promoting artemin release.…”

Tissue injury prompts the release of a number of proalgesic molecules that induce acute and chronic pain by sensitizing pain-sensing neurons (nociceptors) to heat and mechanical stimuli. In contrast, many proalgesics have no effect on cold sensitivity or can inhibit cold-sensitive neurons and diminish cooling-mediated pain relief (analgesia). Nonetheless, cold pain (allodynia) is prevalent in many inflammatory and neuropathic pain settings, with little known of the mechanisms promoting pain vs. those dampening analgesia. Here, we show that cold allodynia induced by inflammation, nerve injury, and chemotherapeutics is abolished in mice lacking the neurotrophic factor receptor glial cell line-derived neurotrophic factor family of receptors-α3 (GFRα3). Furthermore, established cold allodynia is blocked in animals treated with neutralizing antibodies against the GFRα3 ligand, artemin. In contrast, heat and mechanical pain are unchanged, and results show that, in striking contrast to the redundant mechanisms sensitizing other modalities after an insult, cold allodynia is mediated exclusively by a single molecular pathway, suggesting that artemin-GFRα3 signaling can be targeted to selectively treat cold pain.W hen pain continues past its usefulness as a warning of potential tissue damage, it becomes a debilitating condition for which few viable treatments are currently available. The result can be an exacerbation of pain in response to both innocuous (allodynia) and noxious (hyperalgesia) stimuli (1). For example, pain felt with normally pleasant mild cooling (cold allodynia) occurs in many pathological conditions, such as fibromyalgia, multiple sclerosis, stroke, and chemotherapeutic-induced polyneuropathy, but what underlies this specific form of pain at the cellular or molecular level is largely unknown (2-5). Pain-sensing afferent neurons (nociceptors) are sensitized during injury or disease, in part, by a vast array of proalgesic compounds termed the "inflammatory soup" (e.g., neurotrophic factors, protons, bradykinin, prostaglandins, and ATP) (1). These substances are released locally at the site of injury by infiltrating immune cells, such as macrophages, neutrophils, and T cells, as well as resident cells, including keratinocytes and mast cells (6), and either directly activate sensory receptors or sensitize them to subsequent stimuli (7). Moreover, prolonged inflammation can lead to central sensitization (in the spinal cord and brain) and bring about long-lasting chronic pain that persists after acute inflammation has resolved. Thus, a better understanding of the molecules involved in neuroinflammation may lead to therapeutic options for acute and chronic pain.Of the range of proalgesics known to promote pain, only nerve growth factor (NGF) and the glial cell line-derived neurotrophic factor family ligand (GFL) artemin have been shown to lead to cold hypersensitivity (8-11). Both are major components of the inflammatory soup and produce nociceptor sensitization and pain through their cognate cell surface rece...

“…Another very important pathology induced by NGF is thermal hyperalgesia. Injection of NGF into experimental animals induced neutrophil accumulation and hyperalgesia in skin (Bennett et al, 1998). A recent report showed that the involvement of certain integrins, especially the ␤1 subunit, is important in developing mechanical hyperalgesia induced by NGF (Malik-Hall et al, 2005).…”

The integrin α9β1 is a multifunctional receptor that interacts with a variety of ligands including vascular cell adhesion molecule 1, tenascin C and osteopontin. We found that this integrin is a receptor for nerve growth factor (NGF) and two other neurotrophins, brain-derived neurotrophic factor and NT3, using a cell adhesion assay with the α9SW480 cell line. Interaction of α9β1 with NGF was confirmed in an ELISA assay by direct binding to purified integrin. α9β1 integrin binds to neurotrophins in a manner similar to another common neurotrophin receptor, p75NTR (NGFR), although α9β1 activity is correlated with induction of pro-survival and pro-proliferative signaling cascades. This property of α9β1 resembles the interaction of NGF with a high affinity receptor, TrkA, however, this integrin shows a low affinity for NGF. NGF induces chemotaxis of cells expressing α9β1 and their proliferation. Moreover, α9β1 integrin is a signaling receptor for NGF, which activates the MAPK (Erk1/2) pathway. The α9β1-dependent chemotactic ability of NGF appears to result from the activation of paxillin.

“…Leukotrienes produce hyperalgesia in animals (15,16) and human beings (17), and seem to play an important role in the maintenance of a longlasting nociceptive response (18). 5-Lipoxygenase inhibitors such as L-615,919 or ZM 230487 inhibit the hyperalgesia induced by platelet-activating factor (19) or nerve growth factor (20), respectively.…”

The amplification of pain long after the initial stimulus may be avoided if the treatment of pain is introduced before its initiation. However, conflicting evidence exists about the efficacy of such preemptive analgesia for the management of postoperative pain. This study compares the efficacy of intraplantar administration of indomethacin (a non-selective inhibitor of cyclooxygenase) and MK886 (an inhibitor of 5-lipoxygenase-activating protein), separately or in combination to produce preemptive analgesia in a model of surgical incisional pain in male Wistar rats. All incised rats (5 to 6 rats per group) had allodynia at 2, 6, and 24 h after surgery as evaluated using von Frey filaments. MK886, but not indomethacin (50 to 200 µg/ paw), reduced the allodynia when injected either 1 h before or 1 h after surgery. The effect of preoperative MK886 (160 µg/paw) against incisional allodynia had a magnitude apparently similar to that produced by postoperative MK886. Pre-, but not postoperative MK886 (80 µg/paw) reduced the allodynia but the effect was seen only at 6 h after surgery. In contrast, MK886 (40 µg/paw) intensified the allodynia observed 2 h after the incision either injected before or after surgery. MK886 or indomethacin alone did not provide preemptive analgesia in the model of incisional pain. In contrast, the combination of MK886 with indomethacin reduced the allodynia more effectively when used before than after surgery, thus fulfilling the criteria for preemptive analgesia. In conclusion, preoperative inhibition of the local generation of both prostaglandins and leukotrienes by surgical incision may be an alternative to provide preemptive analgesia.
