Abstract
Chronic obstructive pulmonary disease (COPD) is emphysema and/or chronic bronchitis characterised by long-term breathing problems and poor airflow. The prevalence of COPD has increased over the last decade and the drugs most commonly used to treat it, such as glucocorticoids and bronchodilators, have significant therapeutic effects; however, they also cause side effects, including infection and immunosuppression. Here we reviewed the pathogenesis and progression of COPD and elaborated on the effects and mechanisms of newly developed molecular targeted COPD therapeutic drugs. Among these new drugs, we focussed on thioredoxin (Trx). Trx effectively prevents the progression of COPD by regulating redox status and protease/anti-protease balance, blocking the NF-κB and MAPK signalling pathways, suppressing the activation and migration of inflammatory cells and the production of cytokines, inhibiting the synthesis and the activation of adhesion factors and growth factors, and controlling the cAMP-PKA and PI3K/Akt signalling pathways. The mechanism by which Trx affects COPD is different from glucocorticoid-based mechanisms which regulate the inflammatory reaction in association with suppressing immune responses. In addition, Trx also improves the insensitivity of COPD to steroids by inhibiting the production and internalisation of macrophage migration inhibitory factor (MIF). Taken together, these findings suggest that Trx may be the ideal drug for treating COPD.

Abstract
Chronic stages of paracoccidioidomycosis (PCM) are characterized by granulomatous lesions which promote the development of pulmonary fibrosis leading to the loss of respiratory function in 50% of patients; in addition, it has been observed that neutrophils predominate during these chronic stages of P. brasiliensis infection. The goal of this study was to evaluate the role of the neutrophil during the chronic stages of experimental pulmonary PCM and during the fibrosis development and tissue repair using a monoclonal specific to this phagocytic cell. Male BALB/c mice were inoculated intranasally with 1.5x106 P. brasiliensis yeast cells. A monoclonal antibody specific to neutrophils was administered at 4 weeks post-inoculation followed by doses every 48h during two weeks. Mice were sacrificed at 8 and 12 weeks post-inoculation to assess cellularity, fungal load, cytokine/chemokine levels, histopathological analysis, collagen and expression of genes related to fibrosis development. Depletion of neutrophils was associated with a significant decrease in the number of eosinophils, dendritic cells, B cells, CD4-T cells, MDSCs and Treg cells, fungal load and levels of most of the pro-inflammatory cytokines/chemokines evaluated, including IL-17, TNF-α and TGF-β1. Recovery of lung architecture was also associated with reduced levels of collagen, high expression of TGF-β3, matrix metalloproteinase (MMP)-12 and -14, and decreased expression of tissue inhibitor metalloproteinase (TIMP)-2, and MMP-8. Depletion of neutrophils might attenuate lung fibrosis and inflammation through down-regulating TGF-β1, TNF-α, IL-17, MMP-8 and TIMP-2. These results suggest that neutrophil could be considered as a therapeutic target in pulmonary fibrosis induced by P. brasiliensis.

Abstract
The mechanism by which trauma initiates healing remains unclear. Precise understanding of these events may define interventions for accelerating healing that could be translated to the clinical arena. We previously reported that addition of low-dose recombinant human TNF (rhTNF) at the fracture site augmented fracture repair in a murine tibial fracture model. Here, we show that local rhTNF treatment is only effective when administered within 24 h of injury, when neutrophils are the major inflammatory cell infiltrate. Systemic administration of anti-TNF impaired fracture healing. Addition of rhTNF enhanced neutrophil recruitment and promoted recruitment of monocytes through CCL2 production. Conversely, depletion of neutrophils or inhibition of the chemokine receptor CCR2 resulted in significantly impaired fracture healing. Fragility, or osteoporotic, fractures represent a major medical problem as they are associated with permanent disability and premature death. Using a murine model of fragility fractures, we found that local rhTNF treatment improved fracture healing during the early phase of repair. If translated clinically, this promotion of fracture healing would reduce the morbidity and mortality associated with delayed patient mobilization.

Abstract
The C5a/C5a receptor (C5aR) pathway, a key component in the proinflammatory immune response, is an attractive therapeutic target since its dysregulation is implicated in a variety of autoimmune and inflammatory disorders. The objective of the present study was to validate a receptor occupancy (RO) assay for a human anti-C5aR monoclonal antibody drug candidate, NNC0215-0384 (NN0384). This flow cytometry-based assay measures the percentage (%), median fluorescence intensity (MFI), and molecules of equivalent soluble fluorochrome (MESF) of NN0384 binding to its target cells, neutrophils and monocytes, in whole blood from normal healthy donors and rheumatoid arthritis (RA) patients with clinically active disease. The validation parameters assessed included postcollection and postprocessing sample stability, intra- and interassay precision, an analyst-to-analyst comparison, a comparison of normal healthy donor and RA patient sample postcollection stability, and a laboratory-to-laboratory comparison and assay transfer. The cumulative results indicate that the assay was reproducible, met the clearly defined acceptance criteria for the validation parameters tested, and was transferable to another laboratory. In conclusion, this RO assay is suitable for use to accrue pharmacodynamic biomarker data in a multicenter, global clinical trial.

Abstract
Owing to the development of new materials and technology, the pollutants in the environment are becoming more varied and complex over time. In our previous study using ICR mice, we suggested that a single intratracheal instillation of single-walled carbon nanotubes (SWCNTs) induced early lung fibrosis and subchronic tissue damage. In the present study, to investigate the role of CCR5 in inflammatory responses to the uptake of SWCNTs, we compared BAL (Bronchoalveolar lavage) cell composition, cell cycles, cytokines, cell phenotypes, inflammatory response-related proteins, cell surface receptors and histopathology using CCR5 knockout (KO) and wild-type mice. Results showed that the distribution of neutrophils in BAL fluid significantly decreased in KO mice. The expression of apoptosis-related proteins including caspase-3, p53, phospho-p53, p21 and cleaved PARP, TGF βl and mesothelin markedly increased in KO mice compared with wild-type mice. Histopathological lesions were also more frequently noted in KO mice. Moreover, the secretion of IL-13 and IL-17 with IL-6 significantly increased in KO mice compared with wild-type mice, whereas that of IL-12 significantly decreased in comparison to wild-type mice. The distribution of B cells and CD8+ T cells was predominant in the inflammatory responses in KO mice, whereas that of T cells and CD4+ T cells was predominant in the inflammatory responses in wild-type mice. Furthermore, the expression of CCR4 and CCR7 significantly increased in KO mice. Based on these results, we suggest that the absence of CCR5 delays the resolution of inflammatory responses triggered by SWCNTs inflowing into the lungs and shifts inflammatory response for SWCNTs clearance from Th1-type to Th2-type.

Abstract
Neutrophils are among the first cells to arrive at the site of injury. Chemokines secreted by neutrophils affect the migration of both neutrophils and other inflammatory cells, such as monocytes. It has been reported that LPS-induced release of IL-8 (CXCL-8) by neutrophils is amplified by neutrophil-derived TNF-α. We hypothesize that chemokine release by neutrophils is altered in chronic obstructive pulmonary disease (COPD) compared with healthy controls and that TNF-α may be involved in this alteration. Peripheral blood neutrophils isolated from smokers with COPD (n = 12), smokers without COPD (n = 12) and healthy, non-smokers (n = 12) were stimulated with LPS, TNF-α or organic dust. Anti-TNF-α Ab (infliximab) was used to study the effect of neutrophil-derived TNF-α. Release of CXCL-8, macrophage inflammatory protein-1 α (MIP-1α, CCL-3), monocyte chemotactic protein-1 (MCP-1, CCL-2) and TNF-α was measured. Neutrophils spontaneously released CXCL-8, CCL-2 and CCL-3. Inhibition of TNF-α reduced the spontaneous release of CXCL-8 and CCL-3. Stimulation with LPS and organic dust increased the release of CXCL-8 and CCL-3 (but not CCL-2) which was reduced by inhibition of TNF-α. In the COPD group, inhibition of TNF-α failed to inhibit the release of LPS-induced CXCL-8. The role of neutrophils as cytokine and chemokine producers was confirmed. Neutrophil-derived TNF-α contributed to the release of chemokines after stimulation with LPS and organic dust, as the response was inhibited by infliximab. In the COPD group, infliximab did not significantly inhibit the release of CXCL-8, suggesting that the role of TNF-α is altered in COPD.

Abstract
Soluble form of the urokinase-type plasminogen activator receptor (suPAR) is markedly increased in biological fluids during different inflammatory conditions. It has previously been observed that the highest suPAR concentrations in inflammatory exudates tend to be associated with the presence of high number of neutrophils. Guided by this observation and our recent finding that activated neutrophils release suPAR we investigated whether neutrophils can be a source of suPAR during the inflammatory response in vivo. To address this question we conducted the comparative analysis of neutrophils isolated from the paired samples of synovial fluid (SF) and peripheral blood (PB) of rheumatoid arthritis patients. Freshly isolated SF neutrophils released significantly (p < 0.01) higher amounts of suPAR compared with PB neutrophils. We demonstrated that neutrophils from both sources release predominantly the truncated D2D3 form of suPAR. Migration of formyl peptide receptor-like 1 (FPRL1)-transfected human embryonic kidney (HEK) 293 cells toward the supernatants harvested from in vitro cultured SF neutrophils was significantly diminished when D2D3 form of suPAR was immunodepleted from the supernatants. Taken together, these data demonstrate that neutrophils, first, contribute to or are responsible for the generation of the increased suPAR levels during the inflammatory response and, second, release the chemotactically active form of suPAR that might be involved in the recruitment of formyl peptide receptors-expressing leukocytes into the inflamed tissues.

Abstract
The urokinase-type plasminogen activator receptor (uPAR/CD87) exists both in cell-bound and soluble forms. Neutrophils contain extensive intracellular pools of uPAR that are translocated to the plasma membrane upon activation. In the present study, we investigated the ability of human neutrophils to shed uPAR from cell surface following activation and addressed the possible involvement of the released receptor in the inflammatory response. We first observed that the spontaneous release of suPAR by resting neutrophils was strongly and rapidly (within minutes) enhanced by calcium ionophore ionomycin and to a lesser extent when cells were primed with TNF-alpha and then stimulated with fMLP or IL-8. We demonstrated that suPAR is produced by resting and activated neutrophils predominantly as a truncated form devoid of N-terminal D1 domain (D2D3 form) that lacks GPI anchor. Migration of formyl peptide receptor-like 1 (FPRL1)-transfected human embryonic kidney (HEK) 293 cells toward the supernatants harvested from activated neutrophils was significantly diminished when D2D3 form of suPAR was immunodepleted from the supernatants. We conclude that activated neutrophils release the chemotactically active D2D3 form of suPAR that acts as a ligand of FPRL1. Interestingly, we present evidence that GPI-specific phospholipase D (GPI-PLD) that has previously been shown to shed uPAR in cancer cells is not involved in suPAR release from human neutrophils. We suggest that production of the chemotactically active D2D3 form of suPAR by activated human neutrophils in vivo could contribute to the recruitment of monocytes and other formyl peptide receptors-expressing cells to the sites of acute inflammation where neutrophil accumulation and activation occur.
