Abstract
Neurotrophins (NTs) are a group of soluble growth factors with analogous structures and functions, identified initially as critical mediators of neuronal survival during development. Recently, the relevance of NTs has been confirmed by emerging clinical data showing that impaired NTs levels and functions are involved in the onset of neurological and pulmonary diseases. The alteration in NTs expression at the central and peripheral nervous system has been linked to neurodevelopmental disorders with an early onset and severe clinical manifestations, often named "synaptopathies" because of structural and functional synaptic plasticity abnormalities. NTs appear to be also involved in the physiology and pathophysiology of several airway diseases, neonatal lung diseases, allergic and inflammatory diseases, lung fibrosis, and even lung cancer. Moreover, they have also been detected in other peripheral tissues, including immune cells, epithelium, smooth muscle, fibroblasts, and vascular endothelium. This review aims to provide a comprehensive description of the NTs as important physiological and pathophysiological players in brain and lung development.

Abstract
OBJECTIVE Dienogest (DNG), a selective P receptor (PR) agonist, is used to treat endometriosis. To investigate whether DNG affects nerve growth factor (NGF) expression, we stimulated human endometrial epithelial cells (hEECs) with inflammatory cytokines. DESIGN Prospective basic research study using immortalized hEEC lines. SETTING Development Research, Mochida Pharmaceutical Co., Ltd., Japan. PATIENT(S) None. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) In immortalized hEECs, NGF production induced by tumor necrosis factor-α (TNF-α) or interleukin-1β (IL-1β) was evaluated in the presence or absence of the synthetic progestin DNG or endogenous P. The NGF messenger RNA (mRNA) and protein were measured using real-time reverse transcriptase-polymerase chain reaction (PCR) and ELISA, respectively. The NGF bioactivity in the culture medium was measured by assaying neurite outgrowth of PC-12 cells. RESULT(S) Tumor necrosis factor-α and IL-1β induced NGF mRNA and protein and increased NGF bioactivity in the culture medium. These activities were inhibited by DNG in a hEEC line that stably expresses PR. In contrast, in an hEEC line that constitutively expresses faint levels of PR, no inhibitory effect of DNG on NGF mRNA was detected. The NGF mRNA was also inhibited in hEEC lines that express only PR-A or only PR-B. CONCLUSION(S) Nerve growth factor is one of the key mediators that generates the pain associated with endometriosis. Dienogest inhibits NGF expression through PR-A and PR-B in hEEC, which may contribute to the pharmacological mechanisms of how DNG relieves pain in endometriosis.

Abstract
Group 2 allergen of Dermatophagoides pteronyssinus 2 (Der p2) induces airway inflammation without protease activity, and elevated nerve growth factor (NGF) levels are also found in this inflammation. How the allergen Der p2 regulates NGF release via reactive oxygen species (ROS) to induce inflammation remains unclear. In the present study, intratracheal administration of Der p2 to mice led to inflammatory cell infiltration, mucus gland hyperplasia, and NGF upregulation in the bronchial epithelium, as well as elevated ROS and NGF production in bronchoalveolar lavage fluids. In addition, Der p2 caused fibrocyte accumulation and mild fibrosis. p38 mitogen-activated protein kinase (MAPK) and c-Jun N-terminal kinase (JNK) inhibitors inhibited Der p2-induced NGF release in LA4 lung epithelial cells and MLg lung fibroblasts. Pretreatment with an antioxidant, tiron, reduced the Der p2-induced ROS production, NGF expression and release, p38 MAPK or JNK phosphorylation, and airway inflammation. These results suggest that Der p2 allergen-induced airway inflammation and elevated NGF release were through increasing ROS production and a MAPK-dependent pathway. The use of an antioxidant, tiron, may provide a new therapeutic modality for the treatment of allergic asthma.

Abstract
Neurotrophins (NTs) are a family of growth factors that are well-known in the nervous system. There is increasing recognition that NTs (nerve growth factor, brain-derived neurotrophic factor and NT3) and their receptors (high-affinity TrkA, TrkB and TrkC, and low-affinity p75NTR) are expressed in lung components including the nasal and bronchial epithelium, smooth muscle, nerves and immune cells. NT signaling may be important in normal lung development, developmental lung disease, allergy and inflammation (e.g., rhinitis, asthma), lung fibrosis and even lung cancer. In this review, we describe the current status of our understanding of NT signaling in the lung, with hopes of using aspects of the NT signaling pathway in the diagnosis and therapy of lung diseases.

Abstract
Interleukin-1 (IL-1alpha) induced inflammatory and pro-fibrotic responses in human lung fibroblasts are mediated by activation of MAPK and NFkappaB pathways. The purpose of the present study was to broadly profile the activity of a variety of compounds which function as inhibitors of these key signaling pathways that may affect IL-1alpha mediated gene changes. A reference set of genes was derived from microarray analysis of IL-1alpha stimulated cells. The genes were chosen to provide a range of expression profiles which serve to represent the actions of the underlying signaling network. We show that G(s)-coupled receptor agonists have a unique pattern of activity as represented by their impact on IL-1alpha dependent gene changes. These effects were not mimicked by direct inhibitors of p38, JNK, MEK or IKK but were mimicked by forskolin and cAMP analogs. These findings indicate that cAMP/PKA serves as a point of convergence for regulation of IL-1alpha responses by multiple G(s)-coupled receptors and regulates IL-1alpha responses by a distinct mechanism that does not solely involve direct inhibition of p38, JNK, MEK or IKK. The data also point to a potentially useful paradigm wherein monitoring of a small subset of genes is sufficient to identify pathway activity of novel compounds.

Abstract
OBJECTIVE Nerve growth factor (NGF), a neurotrophin, is induced in lung cells by proinflammatory cytokines, and has a role in bronchial hyperreactivity and lung tissue repair. Ventilation induced lung injury, on the other hand, is known to increase the levels of proinflammatory cytokines in the lungs. We investigated whether, and to what extent, various degrees of lung injury induced by short-term ventilation affect NGF levels in the lung tissue of adolescent rabbits. METHODS The rabbits were randomized to different modes of ventilation: (1) CON: normal ventilation for 30 min; (2) NVT: normal ventilation for 6 hr; (3) HFQ: ventilation for 6 hr at double frequency, but normal tidal volume (VT); and (4) HVT: 6 hr ventilation at double VT but normal frequency. RESULTS NGF protein was detected in bronchoalveolar lavage fluid (BALF) and lung tissue in all animals. Ventilation for 6 hr significantly increased NGF levels, in both BALF and lung tissue, in the HFQ and HVT groups as compared to control (P < 0.05). The maximum increase in BALF NGF was seen in the HVT group (P = 0.02 vs. CON and NVT groups, and P = 0.05 vs. HFQ). A parallel increase in interleukin 1-beta (IL1-beta) was observed. Expression of the high-affinity NGF-receptor, tropomyosin-related kinase A (TrkA), was also upregulated in these two groups. CONCLUSION Injurious modes of mechanical ventilation upregulate NGF and its receptor TrkA in rabbit lungs, and IL1-beta may be a mediator for this response. We speculate that this increase in NGF level may translate into the development of bronchial hyperreactivity.

Abstract
BACKGROUND AND OBJECTIVES Nerve growth factor (NGF) and NGF receptors have been shown to be expressed by structural and infiltrating inflammatory cells in the human allergic bronchial mucosa and conjunctiva. In the nose, a positive immunostaining for NGF was recently reported in biopsies of subjects undergoing surgery for refractory nasal obstruction. This study was aimed at studying by immunohistochemistry NGF expression and localization in the nasal mucosa from subjects with moderate/severe persistent allergic rhinitis and natural allergen exposure. METHODS Immunostaining for NGF, tryptase and eosinophil cationic protein was performed in human nasal turbinate sections of 25 patients affected by persistent allergic rhinitis and sensitization to Dermatophagoides pteronyssinus. RESULTS NGF was consistently expressed in the epithelium and in the submucosa of allergic rhinitic subjects, preferentially localized in eosinophils and mast cells. A strong NGF immunostaining was found in mucous cells of the epithelial lining and in the submucosal glands. CONCLUSIONS As previously shown for allergic asthma and allergic conjunctivitis, NGF is also detectable in the nasal mucosa of patients with persistent allergic rhinitis. The preferential NGF localization in mucous cells of the epithelial lining and in the submucosal glands suggests a possible role for NGF in modulating secretion in allergic rhinitis and possibly other allergic diseases.

Abstract
The nerve growth factor (NGF) belongs to the neurotrophin family and induces its effects through activation of 2 distinct receptor types: the tropomyosin-related kinase A (TrkA) receptor, carrying an intrinsic tyrosine kinase activity in its intracellular domain, and the receptor p75 for neurotrophins (p75NTR), belonging to the death receptor family. Through activation of its TrkA receptor, NGF activates signalling pathways, including phospholipase Cgamma (PLCgamma), phosphatidyl-inositol 3-kinase (PI3K), the small G protein Ras, and mitogen-activated protein kinases (MAPK). Through its p75NTR receptor, NGF activates proapoptotic signalling pathways including the MAPK c-Jun N-terminal kinase (JNK), ceramides, and the small G protein Rac, but also activates pathways promoting cell survival through the transcription factor nuclear factor-kappaB (NF-kappaB). NGF was first described by Rita Levi-Montalcini and collaborators as an important factor involved in nerve differentiation and survival. Another role for NGF has since been established in inflammation, in particular of the airways, with increased NGF levels in chronic inflammatory diseases. In this review, we will first describe NGF structure and synthesis and NGF receptors and their signalling pathways. We will then provide information about NGF in the airways, describing its expression and regulation, as well as pointing out its potential role in inflammation, hyperresponsiveness, and remodelling process observed in airway inflammatory diseases, in particular in asthma.
