Abstract
The combination of elexacaftor/tezacaftor/ivacaftor (ETI, Trikafta) reverses the primary defect in Cystic Fibrosis (CF) by improving CFTR mediated Cl - and HCO 3 - secretion by airway epithelial cells (AEC), leading to improved lung function and less frequent exacerbations and hospitalizations. However, studies have shown that CFTR modulators like ivacaftor, a component of ETI, has numerous effects on CF cells beyond improved CFTR channel function. Because little is known about the effect of ETI on CF AEC gene expression we exposed primary human AEC to ETI for 48 hours and interrogated the transcriptome by RNA-seq and qPCR. ETI increased defensin gene expression ( DEFB1 ) an observation consistent with reports of decreased bacterial burden in the lungs of people with CF (pwCF). ETI also decreased MMP10 and MMP12 gene expression, suggesting that ETI may reduce proteolytic induced lung destruction in CF. ETI also reduced the expression of the stress response gene heme oxygenase ( HMOX1 ). qPCR analysis confirmed DEFB1, HMOX1, MMP10 and MMP12 gene expression results observed by RNA-seq. Gene pathway analysis revealed that ETI decreased inflammatory signaling, cellular proliferation and MHC Class II antigen presentation. Collectively, these findings suggest that the clinical observation that ETI reduces lung infections in pwCF is related in part to drug induced increases in DEFB1 , and that ETI may reduce lung damage by reducing MMP10 and MMP12 gene expression, which is predicted to reduce matrix metalloprotease activity. Moreover, pathway analysis also identified several genes responsible for the ETI induced reduction in inflammation observed in people with CF. New and Noteworthy Gene expression responses by CF AEC exposed to ETI suggest that in addition to improving CFTR channel function, ETI is likely to increase resistance to bacterial infection by increasing levels of beta defensin 1 (hBD-1). ETI may also reduce lung damage by suppressing MMP10, and reduce airway inflammation by repressing proinflammatory cytokine secretion by AEC cells.

Abstract
Background In current literature there are only scarce data on the host inflammatory response during Burkholderia cepacia complex (Bcc) persistence. The primary objective of the present research was to carry out cross-sectional analyses of biomarkers and evaluate disease progression in cystic fibrosis (CF) patients with chronic Bcc infection and pathogen-free ones. The secondary aim was to assess prospectively overall survival of the study participants during up to 8 years of follow-up. Methods The study included 116 paediatric patients with CF; 47 CF patients were chronically infected with Bcc, and 69 individuals were Bcc free. Plasma and sputum biomarkers (neutrophil elastase, MMP-8, MMP-9, MMP-12, IL-2, IL-4, IL-6, IL-8, IL-10, IL-18, IL-22, IL-23, IL-17, IFN-γ, TGFβ1, TNF-α) were analysed using commercially available kits. Besides, inhibitory effect of dexamethasone on proliferative response of PHA-stimulated peripheral blood lymphocytes had been assessed. Results Bcc infected patients did not differ from Bcc free ones in demographic and clinical parameters, but demonstrated an increased rate of glucose metabolism disturbances and survival disadvantage during prolong follow-up period. Biomarkers analyses revealed elevated TNF-α and reduced IL-17F levels in sputum samples of Bcc infected patients. These patients also demonstrated improvement of peripheral blood lymphocyte sensitivity to steroid treatment and reduction in plasma pro-inflammatory (IL-17F and IL-18) and anti-inflammatory (TGFβ1 and IL-10) cytokine concentrations. Conclusions Reduction in IL-17F levels may have several important consequences including increase in steroid sensitivity and glycemic control disturbances. Further investigations are needed to clarify the role of IL-17 cytokines in CF complication development. Low plasma TGFβ1 and IL-10 levels in Bcc infected group may be a sign of subverted activity of regulatory T cells. Such immune alterations may be one of the factors contributing to the development of the cepacia syndrome.

Abstract
Introduction With the extensive use of immunosuppressants, immunosuppression-associated pneumonitis including Pneumocystis jirovecii pneumonia (PCP) has received increasing attention. Though aberrant adaptive immunity has been considered as a key reason for opportunistic infections, the characteristics of innate immunity in these immunocompromised hosts remain unclear. Methods In this study, wild type C57BL/6 mice or dexamethasone-treated mice were injected with or without Pneumocystis. Bronchoalveolar lavage fluids (BALFs) were harvested for the multiplex cytokine and metabolomics analysis. The single-cell RNA sequencing (scRNA-seq) of indicated lung tissues or BALFs was performed to decipher the macrophages heterogeneity. Mice lung tissues were further analyzed via quantitative polymerase chain reaction (qPCR) or immunohistochemical staining. Results We found that the secretion of both pro-inflammatory cytokines and metabolites in the Pneumocystis-infected mice are impaired by glucocorticoids. By scRNA-seq, we identified seven subpopulations of macrophages in mice lung tissues. Among them, a group of Mmp12+ macrophages is enriched in the immunocompetent mice with Pneumocystis infection. Pseudotime trajectory showed that these Mmp12+ macrophages are differentiated from Ly6c+ classical monocytes, and highly express pro-inflammatory cytokines elevated in BALFs of Pneumocystis-infected mice. In vitro, we confirmed that dexamethasone impairs the expression of Lif, Il1b, Il6 and Tnf, as well as the fungal killing capacity of alveolar macrophage (AM)-like cells. Moreover, in patients with PCP, we found a group of macrophages resembled the aforementioned Mmp12+ macrophages, and these macrophages are inhibited in the patient receiving glucocorticoid treatment. Additionally, dexamethasone simultaneously impaired the functional integrity of resident AMs and downregulated the level of lysophosphatidylcholine, leading to the suppressed antifungal capacities. Conclusion We reported a group of Mmp12+ macrophages conferring protection during Pneumocystis infection, which can be dampened by glucocorticoids. This study provides multiple resources for understanding the heterogeneity and metabolic changes of innate immunity in immunocompromised hosts, and also suggests that the loss of Mmp12+ macrophages population contributes to the pathogenesis of immunosuppression-associated pneumonitis.

Abstract
Antimicrobial peptides (AMPs) constitute a promising class of alternatives to antibiotics to curb antimicrobial resistance. Nonetheless, their utility as a systemic agent is hampered by short circulation time and toxicity. Infection sites, analogous to tumors, harbor an aberrant microenvironment that has the potential to be exploited to develop conditionally activated therapeutics with an improved therapeutic index. In particular, we identified strategies to prolong systemic circulation of small, cationic AMPs in a mouse model of bacterial pneumonia. Specifically, we report an albumin-binding domain (ABD)-AMP conjugate as a long-circulating conditional AMP therapeutic with a masked activity that can be liberated by proteases in the infected tissue microenvironment. Our systemically administered conjugate enhanced the pulmonary delivery of active AMP while also reducing AMP exposure to other off-target organs. Importantly, this reduction in off-target exposure improved the safety profile of the AMP. The framework we present can be generalized to quantify and optimize the performance of this emerging class of conditional therapeutics.

Abstract
Pseudomonas aeruginosa (PA) infection increases reactive oxygen species (ROS), and earlier, we have shown a role for NADPH oxidase-derived ROS in PA-mediated lung inflammation and injury. Here, we show a role for the lung epithelial cell (LEpC) NOX4 in PA-mediated chromatin remodeling and lung inflammation. Intratracheal administration of PA to Nox4flox/flox mice for 24 h caused lung inflammatory injury; however, epithelial cell-deleted Nox4 mice exhibited reduced lung inflammatory injury, oxidative stress, secretion of pro-inflammatory cytokines, and decreased histone acetylation. In LEpCs, NOX4 was localized both in the cytoplasmic and nuclear fractions, and PA stimulation increased the nuclear NOX4 expression and ROS production. Downregulation or inhibition of NOX4 and PKC δ attenuated the PA-induced nuclear ROS. PA-induced histone acetylation was attenuated by Nox4-specific siRNA, unlike Nox2. PA stimulation increased HDAC1/2 oxidation and reduced HDAC1/2 activity. The PA-induced oxidation of HDAC2 was attenuated by N-acetyl-L-cysteine and siRNA specific for Pkc δ, Sphk2, and Nox4. PA stimulated RAC1 activation in the nucleus and enhanced the association between HDAC2 and RAC1, p-PKC δ, and NOX4 in LEpCs. Our results revealed a critical role for the alveolar epithelial NOX4 in mediating PA-induced lung inflammatory injury via nuclear ROS generation, HDAC1/2 oxidation, and chromatin remodeling.

Abstract
Cedrela odorata L. is a native plant of the Amazon region. The bark is used in folk remedies for the treatment of diarrhea, vomiting, fever and inflammation. Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease accompanied by itching. It is a complex disease involving environmental factors and genetic factors. In the present study, the anti-inflammatory and anti-allergic effects of C. odorata L. methanol extract (COEE) on tumor necrosis factor (TNF)-α and interferon (IFN)-γ-stimulated HaCaT keratinocyte cells were investigated. ELISA and RT-PCR analysis revealed that the extract had anti-inflammatory effects, and reduced the interleukin (IL)-6 and IL-8 levels of the HaCaT cells. In addition, COEE exhibited anti-allergic effects, comprising a reduction in the thymus and activation-regulated chemokine and macrophage-derived chemokine levels. In addition, pathway analysis and comparison with Bay11-7082 indicated that these effects are due to the inhibition of nuclear factor (NF)-κB in TNF-α/IFN-γ-induced HaCaT cells. Therefore, the results of the present study suggest that COEE has anti-inflammatory and anti-allergic properties in TNF-α and IFN-γ-stimulated HaCaT cells, which are associated with the inhibition of pro-inflammatory cytokines and chemokines via the NF-κB pathway.

Abstract
Passiflora foetida L. (Passifloraceae), a perennial climber in general, is used for treating many ailments in conventional medicine. In this study, the anti-inflammatory effect of methanolic extracts of P. foetida L. (PFME) and the involvement of nuclear factor-κB (NF-κB) signalling in the regulation of inflammation were investigated. PFME prevented the production of prostaglandin E2 (PGE2) and the expression of inducible cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-induced macrophage cells. Additionally, PFME reduced the release of pro-inflammatory cytokines. Moreover, in LPS-induced RAW264.7 cells, the phosphorylation of MAPKs (ERK1/2, p38 and JNK) was suppressed by PFME. Furthermore, PFME inhibited the NF-κB activation induced by LPS, which was associated with nuclear p65 levels with the abrogation of IκBα degradation and subsequent decreases. These results indicated that the PFME inhibited the LPS-induced inflammatory and oxidative responses. Therefore, we propose that the PFME may be therapeutic for treating inflammatory diseases.

Abstract
Rhododendron album Blume (RA) has traditionally been used as an herbal medicine and is considered to have anti‑inflammatory properties. It is a well‑known medicine for treatment of allergic or atopic diseases. In the present study, the biological effects of an RA methanol extract (RAME) on inflammation were investigated in tumor necrosis factor‑α (TNF‑α)/interferon‑γ (IFN‑γ)‑stimulated human keratinocytes. The present study aimed to investigate the potential mechanisms by which RAME inhibited TNF‑α/IFN‑γ‑induced expression of chemokines [thymus‑ and activation-regulated chemokine (TARC) and macrophage‑derived chemokine (MDC)] and cytokines [interleukin (IL)‑6 and IL‑8] through the nuclear factor‑κB (NF‑κB) pathway in human keratinocytes. The effects of RAME treatment on cell viability were investigated in TNF‑α/IFN‑γ‑stimulated HaCaT cells. The expression of TARC, MDC, IL‑6 and IL‑8 was assessed using reverse transcription‑quantitative polymerase chain reaction analysis or ELISA, and its effect on the inhibitory mitogen-activated protein kinase pathway was also studied using western blot analysis. TNF‑α/IFN‑γ induced the expression of IL‑6, IL‑8, TARC and MDC in a dose‑dependent manner through NF‑κB and Janus kinase/signal transducers and activators of transcription (JAK/STAT) activation. Notably, treatment with RAME significantly suppressed TNF-α/IFN-γ-induced expression of IL‑6, IL‑8, TARC, and MDC. In addition, RAME treatment inhibited the activation of NF‑κB and the JAK/STAT pathway in TNF‑α/IFN‑γ‑induced HaCaT cells. These results suggest that RAME decreases the production of chemokines and pro‑inflammatory cytokines by suppressing the NF‑κB and the JAK/STAT pathways. Consequently, RAME may potentially be used for treatment of atopic dermatitis.

Abstract
Normal gas exchange after birth requires functional lung alveolar units that are lined with epithelial cells, parts of which are intricately fused with microvascular capillaries. A significant phase of alveolar lung development occurs in the perinatal period, continues throughout early stages in life, and requires activation of matrix-remodeling enzymes. Failure to achieve an optimum number of alveoli during lung maturation can cause several untoward medical consequences including disabling obstructive and/or restrictive lung diseases that limit physiological endurance and increase mortality. Several members of the matrix metalloproteinase (MMP) family are critical in lung remodeling before and after birth; however, their resurgence in response to environmental factors, infection, and injury can also compromise lung function. Therefore, temporal expression, regulation, and function of MMPs play key roles in developing and maintaining adequate oxygenation under steady state, as well as in diseased conditions. Broadly, with the exception of MMP2 and MMP14, most deletional mutations of MMPs fail to perturb lung development; however, their individual absence can alter the pathophysiology of respiratory diseases. Specifically, under stressed conditions such as acute respiratory infection and allergic inflammation, MMP2 and MMP9 can play a protective role through bacterial clearance and production of chemotactic gradient, while loss of MMP12 can protect mice from smoke-induced lung disease. Therefore, better understanding of the expression and function of MMPs under normal lung development and their resurgence in response respiratory diseases could provide new therapeutic options in the future.

Abstract
Mucus overproduction is a fundamental hallmark of COPD that is caused by exposure to cigarette smoke. MUC5AC is one of the main mucin genes expressed in the respiratory epithelium, and its transcriptional upregulation often correlates with increased mucus secretion. Calcium-sensing receptor (CaSR) antagonists have been reported to possess anti-inflammatory effects. The purpose of the present study was to investigate the protective role of NPS2143, a selective CaSR antagonist on cigarette smoke extract (CSE)-stimulated NCI-H292 mucoepidermoid human lung cells. Treatment of NPS2143 significantly inhibited the expression of MUC5AC in CSE-stimulated H292 cells. NPS2143 reduced the expression of MMP-9 in CSE-stimulated H292 cells. NPS2143 also decreased the release of proinflammatory cytokines such as IL-6 and TNF-α in CSE-stimulated H292 cells. Furthermore, NPS2143 attenuated the activation of MAPKs (JNK, p38, and ERK) and inhibited the nuclear translocation of NF-κB in CSE-stimulated H292 cells. These results indicate that NPS2143 had a therapeutic potential in COPD.

Type III Secretion System of Pseudomonas aeruginosa Affects Matrix Metalloproteinase 12 (MMP-12) and MMP-13 Expression via Nuclear Factor κB Signaling in Human Carcinoma Epithelial Cells and a Pneumonia Mouse Model. J Infect Dis 2016; 214:962-9. [PMID: 27377745 DOI: 10.1093/infdis/jiw278] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2016] [Accepted: 06/23/2016] [Indexed: 12/24/2022] Open
Abstract
The type III secretion system (T3SS) in Pseudomonas aeruginosa has been linked to severe disease and poor clinical outcomes in animal and human studies. We aimed to investigate whether the ExoS and ExoT effector proteins of P. aeruginosa affect the expression of matrix metalloproteinase 12 (MMP-12) and MMP-13 via nuclear factor κB (NF-κB) signaling pathways. To understand the T3SS, we used ΔExoS, ΔExoT, and ExsA::Ω mutants, as well as P. aeruginosa strain K (PAK)-stimulated NCI-H292 cells. We investigated the effects of ΔExoS, ΔExoT, and ExsA::Ω on the development of pneumonia in mouse models. We examined the effects of ΔExoS, ΔExoT, and ExsA::Ω on MMP-12 and MMP-13 production in NCI-H292 cells. ΔExoS and ΔExoT markedly decreased the neutrophil count in bronchoalveolar lavage fluid, with a reduction in proinflammatory mediators, MMP-12, and MMP-13. ΔExoS and ΔExoT reduced NF-κB phosphorylation, together with MMP-12 and MMP-13 expression in PAK-infected mouse models and NCI-H292 cells. To conclude, P. aeruginosa infection induced the expression of MMPs, and P. aeruginosa T3SS appeared to be a key player in MMP-12 and MMP-13 expression, which is further controlled by NF-κB signaling. These findings might be useful in devising a novel therapeutic approach to chronic pulmonary infections that involves decreasing the ExoS and ExoT levels.
