Full textLower airway diseases are a common problem in sport and racing horses. Because the innate immunity plays an essential role in lung defense mechanisms against pathogens, we aimed to assess the effect of acute exercise, training and inflammation on pulmonary innate immune responses. In the first step of these PhD research, we evaluate an experimental model to assess equine pulmonary innate immune response which could be used in several conditions. Alveolar macrophages were isolated from broncho-alveolar lavages using an adhesion method and stimulated by TLR 2/6, 3 and 4 agonists. TLR are receptors able to recognize pathogen associated molecular patterns and to induce an immune response. Best conditions of alveolar macrophages stimulations were selected using PCR method. Evaluation of alveolar macrophages response to TLR ligands was performed by measurement of cytokine production in culture supernatants by ELISA. TLR relative expression was quantified by PCR. This experimental model was used in the second step of this work to evaluate the effect of strenuous exercise and training on respiratory innate immunity of horses. A longitudinal study was organized using eight young standardbred horses. Horses were trained and respiratory samplings were performed at different step of the protocol. Results of this study show a moderate effect of strenuous exercise and a negative and prolonged effect of training on alveolar macrophage response against viruses and bacteria. Effect of respiratory inflammation was assessed on owner horses presented at Cirale for respiratory affections. Pulmonary innate immunity was evaluated using the experimental model and compared between healthy horses and horses suffering of IAD and bacterial infection. Results show that alveolar macrophage response of IAD horses was not different from those of healthy horses. Alveolar macrophage response to TLR 4 stimulation was higher in bacterial infection group than in healthy group but the low number of horses included in each group need to take these results with caution. To conclude, this PhD research provides an experimental model to evaluate the ability of alveolar macrophages to recognize pathogens and initiate an immune response. The effect of strenuous exercise and training was assessed using this experimental model and show the negative impact of training on viral and bacterial immunity, which partly explain the high sensitivity of horses to respiratory affections during training periods. Molecular mechanisms involved in IAD stay unknown; complementary studies including higher number of horses should be required to complete these data

Full textResponsible of 1.6 million deaths each year worldwide, lung cancer is today the leading cause of cancer mortality in the world. Non-small-cell lung cancers account for about 85% of lung cancer and have a very bad prognosis (5-year survival rate inferior to 10%). EGFR-TKI (EGFR tyrosine kinase inhibitors, gefitinib) are a real medical advance for lung cancers treatment. However, these treatments are efficient in a small subgroup of patients. So, one of the current issues is to identify primary resistance mechanisms involved in tumors.Tyrosine kinase receptors (RTK) activate intracellular signaling pathways from the plasma membrane. These last years, a nuclear translocation of the RTK was shown. Recent works suggest that RTK nuclear signaling could contribute to tumors resistance in response to anti-cancerous therapies.In our team, it was shown that activation of IGF-1R signaling is associated with lung adenocarcinoma progression and that gefitinib induces IGF-1R nuclear accumulation in a mucinous adenocarcinoma cell line. On the basis of these results, we hypothesize that nuclear IGF-1R could play a role in the resistance of mucinous lung adenocarcinoma to EGFR-TKI.Our results indicate that more than 70% lung adenocarcinoma tumors present a positive IGF-1R nuclear staining. Thanks to EGFR-TKI-resistant cell lines, we show that gefitinib induces the nuclear accumulation of IGF-1R in mucinous adenocarcinoma. This nuclear translocation involves clathrin-mediated endocytosis and a complex between IGF-1R, importin β1 and pro-amphiregulin. Amphiregulin silencing prevents IGF-1R nuclear translocation in response to gefitinib and restores gefitinib-induced apoptosis in vitro and in vivo. Our whole results identify that IGF-1R intracellular trafficking is a new component of response to EGFR-TKI and strongly suggest that a nuclear IGF-1R/amphiregulin signaling contributes to mucinous lung adenocarcinoma progression in response to EGFR-TKI

Full textThe severe infection is the greater reason of the admission into the intensive care unit. Because this challenge is continuous, we should learn to prevent, to understand and to manage it. Our clinical research concerns the prevention of he colonisation due to P. Aeruginosa, the development of a good pactice in antibiotic usage, the decrease of the emergence in antibiotic resistance and the appropriateness of the empiric treatment of the ventilator-associated pneumonia. We have analysed the colonisation by P. Aeruginosa in an intensive care unit, especially in the cases of imunosuppressed patients. After characterize the resistance to quinolones due to mutations in the DNA gyrase and Topoisomerase IV, we have evaluated the positif impact of an antibiotics cycling protocol on the incidence of nosocomial pneumonia and the resistance to βlactams. We have compared the phenotypes of resistance in a context of pneumonia due to P. Aeruginosa and we have evaluated the incidence of the phenotype defined by the overproduction of cephalosporinases

Full textHealthcare-associated infections are the leading cause of death and the first prescription of antibiotics. Healthcare-associated pneumonia represents the first cause of morbidity mortality in ICU. In the context of limited antibiotic resources and an increase in the incidence of resistant germs, we studied:1) Risk factors for ventilator acquired pneumonia (VAP) taking into account the duration of mechanical ventilation (MV).2) If there is a difference between nonventilated and mechanically ventilated pneumonia in terms of etiology and prognostic?3) What is the impact of the adequacy of the initial antibiotic treatment, and what are the risk factors for inadequate treatment in gram-negative resistant VAP?Our results show that: Pneumonia acquired by no ventilated patient in the ICU (ICU-HAP) and VAP are due to the same germs with a higher risk of death in ICU-HAP. Early and late VAP are associated with different risk factors that may need different prevention policies. Previous-antibiotic therapy and prior-colonization with multiresistant bacteria explain the occurrence of resistant Gram Negative VAP. Duration of MV before the onset of pneumonia is no longer an independent risk factor for the occurrence of resistant gram-negative VAP. A percentage of infection or colonization with resistant BGN upper to 10% in the centre is associated with the occurrence of a gram-negative, resistant PAVM, regardless of individual risk factors. S. maltophilia VAP occurs belatedly and are very widely associated with high antibiotic consumption, especially penems. They are more often associated with inadequate initial antibiotic therapy.Our work confirms the need for further research to optimize the diagnosis and early adequacy of antibiotics, in particular in ICU-HAP and VAP caused by potentially antibiotic-resistant BGN

Full textPersonalized medicine for infectious diseases or cancer becomes more and more important in modern therapy. Furthermore, probabilistic treatment has been associated with the development of resistant bacteria causing infectious diseases. As a result, probabilistic treatments are replaced by adapted treatment for pathologies and patients. However, this new approach needs available companion diagnosis tests that are sensitive but also specific tests able to provide rapid pathogen and resistance markers identification in biological fluids. Beside molecular methods, widely developed but with multiplex limits, proteomic technics have recently joined the infectious diagnosis. This work consisted in developing mass spectrometry technics for bacteria and resistance marker identifications. This work focused on 3 applications: 1) identification and quantitation of microorganisms in crude samples (endotracheal aspirates (ETA)) from patient suffering of ventilator associated pneumonia (VAP), 2) detection of genetic elements involved in antibiotic resistance : the integrons, 3) detection of antibiotic resistance phenotypes in S. aureus

Full textDuring my PhD, I have been interested in the role of the innate immune receptor NLRP3, a key component of the inflammasome, in lung cancer development. Our results show the presence of a functional NLRP3 inflammasome in normal human bronchial epithelial cells (HBEC). Surprisingly, NLRP3 expression is strongly down-regulated in a large panel of NSCLC cell lines and patient tumors compared to healthy tissue. Moreover, we unravel that NLRP3 contributes to the transcription of H2AFX, the coding gene for the histone variant H2AX, in an inflammasome independent-manner. The deletion of NLRP3 in HBEC impairs double strand break signal amplification and transduction, resulting in a decrease in DNA repair. This repair defect leads to genomic instability, which is increased in lung adenocarcinomas expressing low levels of NLRP3. My PhD work identifies NLRP3 as a key factor of the DNA damage response and genomic integrity maintenance by regulating the transcription of H2AFX. This new role for NLRP3, together with its loss in NSCLC, makes it as a potential tumor suppressor

Full textVariola virus was declared eradicated in 1980 after a worldwide vaccination campaign. A better understanding of the infection process of orthopoxviruses is nevertheless necessary because of the potential release of variola by bioterrorists. Here we report potential counter-measures against Variola virus that could result from studying mechanisms of viral entry and immunity against Variola virus. The purpose of this work was to study multiple factors in vaccinia virus entry in the lung and thus gain a better understanding of the infectious process that could be used to stop infection by Orthopoxvirus. The innate immune functions displayed by some phospholipids (DiPalmitoyl PhosphatidylGlycerol) in lung surfactant were studied. The discovery of the ability of DPPG to inhibit vaccinia virus infection in cell culture led to the evaluation of its in vivo activity during a lethal vaccinia virus infection. Furthermore, the analysis of the interaction between vaccinia virus and plasma membrane lipids (sulfatide) enabled the definition of a secondary receptor for vaccinia virus in addition to glycosaminoglycans that were characterized previously. Finally, examination of the specific innate immunity provided by proteins in lung surfactant allowed us to highlight interactions between one surfactant protein (Surfactant protein D) and vaccinia virus. These interactions were then characterized as inhibitory interactions for vaccinia virus infection. Our findings underline the importance of lipids and proteins inlung surfactant as well as lipids in the plasma membrane in the Poxvirus infection and suggest that these molecules may be potential new targets for the development of new therapeutic and prophylactic products to efficiently treat poxvirus infection

Full textPatients hospitalized in intensive care units are at high-risk of acquiring infections because of their high severity and high exposure to invasive devices. One part of these infections may probably be avoided using effective measures, especially the part associated with care activities. This thesis presents the studies we conducted in this field with a first part focusing on the prevention of ventilator-associated pneumonia (VAP) and a second part discussing the prevention of cross transmission via hands. For VAP prevention, the use of noninvasive ventilation was associated with a significant reduction of VAP and other sites of infection whereas, in another study, the use of subglottic secretions drainage and semi-recumbent position had no effect on tracheal colonization, which normally precedes lung infection. We also demonstrated that the use of alcoholic hand-rubs, the rational use of gloves and, the screening of multiresistant Staphylococcus aureus on admission might help limiting cross transmission of microorganisms in intensive care units
