Abstract
Pneumonia is inflammation in the lungs, which is usually caused by an infection. The symptoms of pneumonia can vary from mild to life-threatening, where severe illness is often observed in vulnerable populations like children, older adults, and those with preexisting health conditions. Vaccines have greatly reduced the burden of some of the most common causes of pneumonia, and the use of antimicrobials has greatly improved the survival to this infection. However, pneumonia survivors do not return to their preinfection health trajectories but instead experience an accelerated health decline with an increased risk of cardiovascular disease. The mechanisms of this association are not well understood, but a persistent dysregulated inflammatory response post-pneumonia appears to play a central role. It is proposed that the inflammatory response during pneumonia is left unregulated and exacerbates atherosclerotic vascular disease, which ultimately leads to adverse cardiac events such as myocardial infarction. For this reason, there is a need to better understand the inflammatory cross talk between the lungs and the heart during and after pneumonia to develop therapeutics that focus on preventing pneumonia-associated cardiovascular events. This review will provide an overview of the known mechanisms of inflammation triggered during pneumonia and their relevance to the increased cardiovascular risk that follows this infection. We will also discuss opportunities for new clinical approaches leveraging strategies to promote inflammatory resolution pathways as a novel therapeutic target to reduce the risk of cardiac events post-pneumonia.

Free Radic Biol Med 2022; 191:164-175.

Abstract
In previous studies, propofol has shown immunomodulatory abilities on various in vitro models. As this anesthetic molecule is extensively used in intensive care units, its anti-inflammatory properties present a great interest for the treatment of inflammatory disorders like the systemic inflammatory response syndrome. In addition to its inhibition abilities on important neutrophils mechanisms (chemotaxis, reactive oxygen species (ROS) production, Neutrophil Extracellular Traps (NETs) formation, …), our group has shown that propofol is also a reversible inhibitor of the oxidant myeloperoxidase (MPO) activity. Propofol being subject to rapid metabolism, its derivatives could contribute to its anti-inflammatory action. First, propofol-β-glucuronide (PPFG), 2,6-diisopropyl-1,4-p-benzoquinone (PPFQ) and 3,5,3',5'-tetraisopropyl-(4,4')-diphenoquinone (PPFDQ) were compared on their superoxide (O2.-) scavenging properties and more importantly on their inhibitory action on the O2.- release by activated neutrophils using EPR spectroscopy and chemiluminescence assays. PPFQ and PPFDQ are potent superoxide scavengers and also inhibit the release of ROS by neutrophils. An Enzyme-Linked Immunosorbent Assay (ELISA) has also highlighted the ability of both molecules to significantly decrease the MPO degranulation process of neutrophils. Fluorescence enzymatic assays helped to investigate the action of the propofol derivatives on the peroxidase and chlorination activities of MPO. In addition, using SIEFED (Specific Immunological Extraction Followed by Enzyme Detection) assays and docking, we demonstrated the concentration-dependent inhibitory action of PPFQ and its ability to bind to the enzyme active site while PPFG presented a much weaker inhibitory action. Overall, the oxidation derivatives and metabolites PPFQ and PPFDQ can, at physiological concentrations, perpetuate the immunomodulatory action of propofol by acting on the oxidant response of PMN and MPO.

Abstract
Improved tuberculosis (TB) prevention and control depend critically on the development of a simple, readily accessible rapid triage test to stratify TB risk. We hypothesized that a blood protein-based host response signature for active TB (ATB) could distinguish it from other TB-like disease (OTD) in adult patients with persistent cough, thereby providing a foundation for a point-of-care (POC) triage test for ATB. Three adult cohorts consisting of ATB suspects were recruited. A bead-based immunoassay and machine learning algorithms identified a panel of four host blood proteins, interleukin-6 (IL-6), IL-8, IL-18, and vascular endothelial growth factor (VEGF), that distinguished ATB from OTD. An ultrasensitive POC-amenable single-molecule array (Simoa) panel was configured, and the ATB diagnostic algorithm underwent blind validation in an independent, multinational cohort in which ATB was distinguished from OTD with receiver operator characteristic-area under the curve (ROC-AUC) of 0.80 [95% confidence interval (CI), 0.75 to 0.85], 80% sensitivity (95% CI, 73 to 85%), and 65% specificity (95% CI, 57 to 71%). When host antibodies against TB antigen Ag85B were added to the panel, performance improved to 86% sensitivity and 69% specificity. A blood-based host response panel consisting of four proteins and antibodies to one TB antigen can help to differentiate ATB from other causes of persistent cough in patients with and without HIV infection from Africa, Asia, and South America. Performance characteristics approach World Health Organization (WHO) target product profile accuracy requirements and may provide the foundation for an urgently needed blood-based POC TB triage test.

Abstract
Rosa rugosa Thunb., is as a medicinal plant known for anti‐diabetic, and anti‐inflammatory activities. However, the specific active compounds responsible for the individual pharmacological effects of in R. rugosa extract (95% EtOH) remain unknown. Here, we hypothesized that terpenoid structure, the most abundant constituents in R. rugosa extract, are responsible for its anti‐inflammatory activity. We investigated the phytochemical substituents (compounds 1–13) and newly purified 11‐methoxy polisin A, and 13‐methoxy bisaborosaol F using NMR and ESI‐MS and to screened their effects on NO production in LPS‐induced macrophages. Rugosic acid A (RA) induced to ameliorate NO production, iNOS, and pro‐inflammatory cytokines associated with the NF‐κB. And, RA suppressed IL‐6 secretion and IL‐6‐mediated STAT3 activation in LPS‐mediated inflammation. In addition, RA was evaluated in LPS‐mediated acute lung injury (ALI) model similar to acute pneumonia. Our results suggested that RA was suppressed to translocate nuclear NF‐κB and IL‐6‐mediated STAT3 activation. Finally, RA led to amelioration of ALI by decreasing myeloperoxidase (MPO) and inhibiting phosphorylation of NF‐κB and STAT3. Our group originally found that R. rugosa extract had new methoxy compounds and RA may be alternative natural agent for acute pneumonia similar to severe acute respiratory syndrome by coronavirus.

Abstract
The generation of an innate immune response is essential for rapid clearance of microbes from the respiratory tract, whereas acquired immunity is required for the generation of cellular immunity necessary for the killing of certain intracellular pathogens and the development of immunological memory. Cytokines play an integral role in host defense by serving as leukocyte chemoattractants, leukocyte-activating factors or afferent signals in the induction or regulation of other effector molecules. This review assesses the contribution of cytokine networks to the generation of antimicrobial host defenses in the lung, with an emphasis on cytokines/cytokine networks that are instrumental in innate antibacterial responses, including mucosal immunity, and also introduces networks that instruct the development of adaptive immunity.

Abstract
CD47 modulates neutrophil transmigration toward the sites of infection or injury. Mice lacking CD47 are susceptible to Escherichia coli (E. coli) peritonitis. However, less is known concerning the role of CD47 in the development of acute lung inflammation and injury. In this study, we show that mice lacking CD47 are protected from LPS-induced acute lung injury and E. coli pneumonia with a significant reduction in pulmonary edema, lung vascular permeability, and bacteremia. Reconstitution of CD47(+/-) mice with CD47(-/-) neutrophils significantly reduced lung edema and neutrophil infiltration, thus demonstrating that CD47(+) neutrophils are required for the development of lung injury from E. coli pneumonia. Importantly, CD47-deficient mice with E. coli pneumonia had an improved survival rate. Taken together, deficiency of CD47 protects mice from LPS-induced acute lung injury and E. coli pneumonia. Targeting CD47 may be a novel pathway for treatment of acute lung injury.

Abstract
Mechanical ventilation with hyperoxia is necessary to treat critically ill patients. However, prolonged exposure to hyperoxia leads to the generation of excessive reactive oxygen species (ROS), which can cause acute inflammatory lung injury. One of the major effects of hyperoxia is the injury and death of pulmonary epithelium, which is accompanied by increased levels of pulmonary proinflammatory cytokines and excessive leukocyte infiltration. A thorough understanding of the signaling pathways leading to pulmonary epithelial cell injury/death may provide some insights into the pathogenesis of hyperoxia-induced acute inflammatory lung injury. This review focuses on epithelial responses to hyperoxia and some of the major factors regulating pathways to epithelial cell injury/death, and proinflammatory responses on exposure to hyperoxia. We discuss in detail some of the most interesting players, such as NF-kappaB, that can modulate both proinflammatory responses and cell injury/death of lung epithelial cells. A better appreciation for the functions of these factors will no doubt help us to delineate the pathways to hyperoxic cell death and proinflammatory responses.

Abstract
We have demonstrated earlier that lysophosphatidic acid (LPA)-induced interleukin-8 (IL-8) secretion is regulated by protein kinase Cdelta (PKCdelta)-dependent NF-kappaB activation in human bronchial epithelial cells (HBEpCs). Here we provide evidence for signaling pathways that regulate LPA-mediated transactivation of epidermal growth factor receptor (EGFR) and the role of cross-talk between G-protein-coupled receptors and receptor-tyrosine kinases in IL-8 secretion in HBEpCs. Treatment of HBEpCs with LPA stimulated tyrosine phosphorylation of EGFR, which was attenuated by matrix metalloproteinase (MMP) inhibitor (GM6001), heparin binding (HB)-EGF inhibitor (CRM 197), and HB-EGF neutralizing antibody. Overexpression of dominant negative PKCdelta or pretreatment with a PKCdelta inhibitor (rottlerin) or Src kinase family inhibitor (PP2) partially blocked LPA-induced MMP activation, proHB-EGF shedding, and EGFR tyrosine phosphorylation. Down-regulation of Lyn kinase, but not Src kinase, by specific small interfering RNA mitigated LPA-induced MMP activation, proHB-EGF shedding, and EGFR phosphorylation. In addition, overexpression of dominant negative PKCdelta blocked LPA-induced phosphorylation and translocation of Lyn kinase to the plasma membrane. Furthermore, down-regulation of EGFR by EGFR small interfering RNA or pretreatment of cells with EGFR inhibitors AG1478 and PD158780 almost completely blocked LPA-dependent EGFR phosphorylation and partially attenuated IL-8 secretion, respectively. These results demonstrate that LPA-induced IL-8 secretion is partly dependent on EGFR transactivation regulated by PKCdelta-dependent activation of Lyn kinase and MMPs and proHB-EGF shedding, suggesting a novel mechanism of cross-talk and interaction between G-protein-coupled receptors and receptor-tyrosine kinases in HBEpCs.

Abstract
We describe a novel chemotaxis assay based on the microvalve-actuated release of a chemoattractant from a cell-free microchamber into a cell-containing microchamber. The microvalve chemotaxis device (microVCD) was placed on the stage of a conventional inverted microscope to obtain time-lapse micrographs of neutrophils migrating in a radially-symmetric evolving gradient of the chemotactic factor CXCL8/Interleukin-8. A fluorescent tracer was added to the CXCL8 solution to visualize the evolution of the gradient profile, so that at each time point the cell positions could be assigned CXCL8 concentration values. Tracking of individual neutrophils for 90 minutes showed that (a) the neutrophil migratory response is, on average, radially directed towards the CXCL8 source; (b) significant non-radial displacements occur frequently; and (c) there is considerable heterogeneity in the migration speeds and directions amongst the neutrophil population. A custom-made imaging analysis tool was used to extract measurements of migratory behavior such as speed, velocity along the gradient's radial axis, and the cosine of the turning angle as a function of CXCL8 concentration. The microVCD can be easily adapted to study the migratory behavior of cultured cells other than neutrophils.

A custom-made imaging analysis tool was used to extract measurements of migratory behavior such as speed, velocity along the gradient's radial axis, and the cosine of the turning angle as a function of CXCL8 concentration. The microVCD can be easily adapted to study the migratory behavior of cultured cells other than neutrophils.

Abstract
Lysophosphatidic acid (LPA), a potent bioactive lipid, elicits many of its biological actions via the specific G-protein-coupled receptors LPA1, LPA2, LPA3, and LPA4. Recently, we have shown that LPA-induced transactivation of platelet-derived growth factor receptor-beta is regulated by phospholipase D2 in human bronchial epithelial cells (HBEpCs) (Wang, L., Cummings, R. J., Zhao, Y., Kazlauskas, A., Sham, J., Morris, A., Brindley, D. N., Georas, S., and Natarajan, V. (2003) J. Biol. Chem. 278, 39931-39940). Here, we report that protein kinase Cdelta (PKCdelta) mediates LPA-induced NF-kappaB transcription and interleukin-8 (IL-8) secretion in HBEpCs. Treatment of HBEpCs with LPA increased both IL-8 gene and protein expression, which was coupled to Gi and G(12/13) proteins. LPA caused a marked activation of NF-kappaB in HBEpCs as determined by IkappaB phosphorylation and of NF-kappaB nuclear translocation and a strong induction of NF-kappaB promoter-mediated luciferase activity. Furthermore, LPA-activated PKCdelta and the LPA-mediated activation of NF-kappaB and IL-8 production were attenuated by overexpression of dominant-negative PKCdelta and rottlerin. Intratracheal administration of LPA in mice resulted in elevated levels of macrophage inflammatory protein-2, a murine homolog of IL-8, and an influx of neutrophils in the bronchoalveolar lavage fluid. These results demonstrate for the first time that LPA is a potent stimulator of IL-8 production in HBEpCs, which involves PKCdelta/NF-kappaB signaling pathways.

Abstract
BACKGROUND Tumor necrosis factor alpha as a central mediator of the inflammation cascade is correlated to sepsis outcome. Tumor necrosis factor beta (LT-alpha) binds the same cell receptor and polymorphisms in both genes have been described. To evaluate the importance of the LT-alpha (+250 G/A) polymorphism for the clinical outcome of patients developing postsurgical sepsis, 85 patients were consecutively included into this study. METHODS Blood samples were obtained for analysis of the biallelic LT-alpha (+250 G/A) polymorphism and for determination of serum levels of sTNF-R1, TNF-alpha, IL-6, IL-8, IL-10, procalcitonin, and neopterin. Cytokine levels were measured repeatedly until the patients' discharge from the ICU. RESULTS The allele frequency was 0.28 for TNFB1 and 0.72 for TNFB2. The genotype distribution was TNFB1 homozygotes 4/79 (5.1%), TNFB1/TNFB2 heterozygotes 37/79 (46.8%), and TNFB2 homozygotes 38/79 (48.1%). Fifty-four out of 80 (67.5%) fulfilled the criteria for severe sepsis; 36/80 (45.0%) developed septic shock. Multiple organ failure occurred in 60/80 patients (75.0%), and the overall mortality was 26/80 (32.5%). Concerning the LT-alpha-genotypes, there was no difference in the frequency of severe sepsis or shock or in the development of multi-organ failure or death between the three subgroups. The peak plasma TNF-alpha levels were similar for all genotype subgroups. CONCLUSIONS There was no correlation between the biallelic LT-alpha (+250 G/A) polymorphism and the outcome of critically ill patients. Genotyping this locus does not seem to be useful in predicting sepsis outcome.

Abstract
We analyzed the characteristics of the inflammatory response occurring in blood during pulmonary infections in human immunodeficiency virus (HIV)-infected patients. A prospective study of consecutive hospital admissions of HIV-infected patients with new-onset radiologic pulmonary infiltrates was carried out in a tertiary university hospital from April 1998 to May 2001. Plasma cyclic AMP receptor protein (CRP), interleukin 1beta (IL-1beta), IL-6, IL-8, IL-10, and tumor necrosis factor alpha (TNF-alpha) levels were determined at the time of admission and 4, 5, and 6 days later. Patients were included in a protocol addressed to study etiology and outcome of disease. A total of 249 episodes of infection were included, with the main diagnoses being bacterial pneumonia (BP) (118 episodes), Pneumocystis carinii pneumonia (PCP) (41 episodes), and mycobacteriosis (36 episodes). For these three patient groups, at the time of admission the median CRP and cytokine levels were as follows: CRP, 10.2, 3.8 and 5 mg/dl, respectively (P = 0.0001); IL-8, 19, 3, and 2.9 pg/ml (P = 0.045); and TNF-alpha, 46.4, 44, and 75 pg/ml, respectively (P = 0.029). There were no significant differences in levels of IL-1beta, IL-6, or IL-10 among the patient groups. A total of 23 patients died. At the time of admission, HIV-infected patients with BP had higher plasma CRP and IL-8 levels than did PCP and mycobacteriosis patients. TNF-alpha levels were higher in patients with mycobacteriosis. An elevated IL-8 level (>61 pg/ml) at the time of admission was an independent factor associated with higher mortality (odds ratio, 12; 95% confidence interval, 1.2 to 235.5).

Abstract
Interleukin (IL)-8, a member of the CXC chemokine family, is a potent neutrophil chemotactic factor. Mechanisms that regulate the activity of chemokines in tissue are not clear. The goal of this study was to determine whether IL-8-glycosaminoglycan interactions are responsible for the binding of IL-8 in lung tissue. Experiments were performed with a quantitative tissue-binding assay to measure the amount of 125I-IL-8 binding and an in situ tissue-binding assay to characterize the location of IL-8 binding in lung tissue. Confocal microscopy demonstrated IL-8 binding to specific anatomic locations such as cell surfaces and extracellular matrix that were enriched with heparan sulfate and chondroitin sulfate. Removal of heparan sulfate or chondroitin sulfate from lung tissue significantly decreased the binding of 125I-IL-8. Two forms of IL-8 with single amino acid mutations in the glycosaminoglycan-binding domain showed decreased binding. In addition, studies with normal and monomeric IL-8 showed that dimerization increased the binding of 125I-IL-8 in lung tissue. These findings suggest that IL-8-glycosaminoglycan interactions determine the location where IL-8 binds in lung tissue and provides a site for the dimerization of IL-8, which increases the local concentration of IL-8 in the lungs.

Abstract
Cytokines are key regulators of the host response to infection, controlling the inflammatory reaction which is an essential component of the defense mechanisms. The major importance of these proteins in the pathogenesis and outcome of infectious diseases has been clearly demonstrated. In humans, there is increasing evidence that the host's cytokine response is genetically determined and that the genetic variability of cytokines underlies the complexity of interindividual differences in the immune response to micro organism invasions. We review the influence of host cytokine gene on the susceptibility to and the severity of parasitic, bacterial and viral infections. Proinflammatory cytokine polymorphisms are discussed in detail because of their importance in the course of severe infections such as meningococcal disease, cerebral malaria and septic shock. Genetic variants of the IL-10 gene, an antiinflammatory cytokine appear to be responsible for an uncontrolled and intense CARS and may have also dramatic consequences as an overwhelming inflammatory response. Our greater understanding of the genetic factors that influence mortality and morbidity of infectious diseases will permit identification of genomic markers which may be required for risk stratification of patients targeted for novel immunomodulatory treatments helping clinicians to select the most appropriate treatment options for their patients.
