Correlação dos ligantes de quimiocinas e de seus respectivos receptores em relação à invasão de linfonodos nos carcinomas epidermóides em cabeça e pescoço / Correlation of chemokine ligands and its receptors with lymph node metastasis in Head and Neck Squamous Cell Carcinoma

Cristina Maria Meireles Campofiorito 02 March 2007 (has links)
Tanto a invasão local como o comprometimento de linfonodos cervicais tem grande impacto na sobrevida de pacientes portadores de carcinomas epidermóides de cabeça e pescoço. Em nosso trabalho nós primeiramente determinamos a expressão dos receptores de quimiocinas de CXCR1 a CXCR5, além de CCR7 e CX3CR1 pelo método do ensaio de proteção à ribonuclease (RPA) em 98 fragmentos de tumores primários, 91 fragmentos de mucosas adjacentes e 26 linfonodos comprometidos e correlacionamos estes dados com parâmetros anátomo-patológicos e sobrevida. CXCL12 ligante do receptor CXCR4 e CCL19 e CCL21 ambos ligantes de CCR7 foram determinados em 38 fragmentos de tumores, 33 mucosas adjacentes e 25 linfonodos comprometidos pela técnica de real-time PCR. Os tumores primários apresentam expressão aumentada do mRNA de CXCR1 (P=0.013), CXCR3 (P=0.008) e CXCR4 (P=0.025). Não observamos correlações entre status linfonodal ou tamanho de tumor. Os linfonodos comprometidos expressam mais mRNA dos receptores de quimiocinas CXCR4, CXCR5, CCR7 e CX3CR1 (todos com P<0.0001) em comparação aos tumores comprometidos. Observamos um aumento de sobrevida (P=0.048) e uma tendência a aumento de sobrevida livre de doença (P=0.074) nos pacientes negativos para a expressão de CX3CR1 (n=17) em comparação aos pacientes positivos (n=21) somente no subgrupo de pacientes portadores de carcinomas da cavidade oral. O mesmo foi observado com os pacientes CCR7 negativos também no subgrupo de pacientes portadores de carcinomas da cavidade oral, tanto em sobrevida global (P=0.024) como para sobrevida livre de doença (P=0.049). Em relação aos ligantes de quimiocinas observamos um aumento do mRNA de CCL21 em linfonodos comprometidos em relação aos tumores primários (P=0.059). Concluímos que a interação quimiotática entre CCR7 e de seu ligante CCL21, poderia ser um mecanismo de atração de células tumorais para os linfonodos em tumores de cavidade oral, além disso a negatividade da expressão do mRNA de CCR7 e CX3CR1 são candidatos marcadores de uma melhor sobrevida em carcinomas epidermóides de cavidade oral. / Local invasion and lymph nodal spread impact in the outcome of Head and Neck squamous cell carcinoma (HNSCC) patients (pts). We determined CXCR1-5, CCR7 and CX3CR1 mRNA expression by means of RNAse protection assay in 98 HNSCC primary tumors and 91 adjacent mucosa and 26 metastatic lymph nodes, correlating this data with outcome. CXCL12 and CCL19/CCL21, ligands for CXCR4 and CCR7, were determined in 38 tumor fragments, 33 adjacent mucosas and 25 de metastatic lymph nodes, by means of Quantitative Real-Time PCR. Tumors presented higher CXCR1 (P=0.013), CXCR3 (P=0.008) and CXCR4 mRNA (P=0.025) expression as compared to mucosa. No correlations are observed neither lymph nodal status nor tumor size impacted on chemokine receptor expression. Metastatic lymph nodes expressed more CXCR4, CXCR5, CCR7 and CX3CR1 (P<0.0001) as compared to matched tumors. We found a longer overall survival (OS) (P=0.048) and a trend toward longer disease free survival (DFS) (P=0.074) in CX3CR1 negative (n=17) as compared to positive pts (n=21) only in oral subgroup. The same occurred for CCR7 negative oral SCC, in terms of OS (P=0.024) and DFS (P=0.049). We conclude that, of the chemokine receptors here studied, CCR7 and CX3CR1 mRNA expression seems to better reflect outcome in oral subsite only. In addition, CCL21, a CCR7 ligand mRNAs is more expressed in metastatic lymph nodes than tumors (P=0.059). Further studies are warranted to confirm these results.

Rôle du récepteur de chimiokines CCR2 dans la dynamique des lymphocytes T régulateurs et monocytes/macrophages en réponse aux thérapies antitumorales / Role of the chemokine receptor CCR2 in the dynamic of regulatory T cells and monocytes/macrophages in response to antitumor therapies

Loyher, Pierre-Louis 17 March 2017 (has links)
Une forte production de la chimiokine CCL2 par les cellules malignes et les cellules stromales a été démontrée dans la plupart des cancers humains. Ainsi, l’axe chimiokinique CCR2/CCL2 est un important marqueur du développement des cancers ; ce même axe est associé à la récurrence de tumeurs après thérapie anticancéreuses. Les macrophages associés aux tumeurs (TAM) et les lymphocytes T régulateurs (Treg) ont des capacités immunosuppressives robustes et contribue à la croissance tumorale. Durant cette thèse, je me suis intéressé à la fonction de l’expression du récepteur de chimiokine CCR2 par ces cellules dans le contexte de thérapies anticancéreuses. Nous avons montré que le récepteur de chimiokines CCR2 contrôle la migration des Treg en contexte tumoral, chez l’homme et la souris, et que son expression par les Treg peut servir de biomarqueur de la réponse à la chimiothérapie. Notre étude indique une nouvelle fonction de CCR2 et définie un nouveau sous-type de Treg impliqué dans la régulation de l’immunité antitumorale. En parallèle, nous avons pu mettre en évidence que les métastases pulmonaire sont composées à la fois de macrophages résident du tissu et de macrophages recrutés via l’axe CCR2. La présence de macrophages résidents au sein des tumeurs pourrait contribuer à l’hétérogénéité des microenvironnements de diffèrent type de tumeurs. Le récepteur CCR2 est important pour le la phase de rechute après chimiothérapie, indiquant un rôle limité des macrophages résidents dans ce phénomène. De plus, nous avons montré que le VEGF joue un rôle direct dans la survie des TAM. Ainsi, la combinaison de la chimiothérapie avec un anticorps anti-VEGF cible simultanément les TAM résidents et recrutés et permet d’augmenter l’efficacité de la chimiothérapie. / Malignant and stromal cells are strong producer of the chemokine CCL2 in most human cancers. The chemokine axis CCR2/CCL2 is thus a key marker of cancer development, but is also associated with relapse following therapy. Tumour associated macrophages (TAM) and regulatory T cells (Treg) display robust immunosuppressive capacities and contribute to tumour growth. My thesis work focused on the function of the expression of the chemokine receptor CCR2 by these cell types in the context of anticancer therapies. We have shown that CCR2 controls the migration of Treg in tumoral context, in both human and mice, and that the expression of this receptor by Treg could serve as a biomarker of the response to chemotherapy. Our study indicate a novel function of CCR2, defining at the same time a new Treg subset implicated in the regulation of antitumor immunity.We have also demonstrated that pulmonary metastases are composed of both tissue resident and recruited macrophages. The presence of resident macrophages within tumours could contribute to the heterogeneity of the microenvironment of different tumour types. CCR2 is largely implicated in the relapse phase following chemotherapy, indicating a limited role for resident macrophages in this phenomenon. Meanwhile, we have demonstrated that VEGF plays a direct role in TAM survival. The combination of chemotherapy with an anti-VEGF antibody targets both resident and recruited TAM, thereby enhancing the efficacy of chemotherapy. Finally, we have shown that the CCR2/CCL2 axis is implicated in the response to radiotherapy by enhancing the recruitment of both Treg and TAM. This work provides evidences for a central role of the CCR2/CCL2 axis in mediating Treg and TAM co-localization in response to anticancer therapy, this axis could also contribute to establishment of immunosuppressive networks in tumours. Our results provide a better understanding of the immune mechanism implicated in resistance to anticancer therapies.

Perturbations de l'homéostasie lymphocytaire T chez le macaque rhésus chinois en phase aiguë d'infection par le SIVmac251 / T-cell homeostasis disruption during acute SIVmac251 infection of Chinese rhesus macaques

Ponte, Rosalie 09 October 2014 (has links)
Le macaque rhésus infecté par le virus de l’immunodéficience simienne (SIV) fait l’objet de nombreuses études en tant que modèle de la pathogenèse induite par le virus de l’immunodéficience humaine de type 1 (VIH-1). Il existe deux sous-espèces de macaque rhésus définies notamment d’après leur origine géographique. Le macaque rhésus indien montre une progression pathologique particulièrement rapide, caractérisée par une déplétion massive de la population lymphocytaire T CD4+ intestinale les jours suivant l’infection. Cette déplétion a été associée à la translocation des bactéries commensales à travers l’épithélium intestinal en phase chronique. En revanche, chez le macaque rhésus chinois la vitesse de développement de la maladie est comparable à celle des patients infectés par le VIH-1. En périphérie, les données virales et immunologiques sont également plus proches de ce qui est documenté chez l’Homme infecté. Toutefois, la cinétique de dégradation de la muqueuse intestinale les jours suivant l’infection reste peu explorée dans ce modèle. Dans un premier temps, mes travaux de doctorat ont permis de confirmer la dissémination rapide du SIV dans le tractus gastro-intestinal du macaque rhésus d’origine chinoise. L’intestin grêle, notamment l’iléon, est la cible d’une réplication virale soutenue et très précoce. Malgré une réplication virale intense, le nombre de lymphocytes T CD4+ dans la muqueuse de l’iléon reste constant durant les deux premières semaines suivant l’infection par le virus dans ce modèle. Nous observons en revanche une augmentation conséquente du nombre de cellules T cytotoxiques et de macrophages, suggérant la mise en place d’une forte réponse immune in situ. Nous démontrons que l’augmentation du nombre de ces cellules et le maintien du nombre de lymphocytes T CD4+ dans la muqueuse iléale sont certainement liés, du moins en partie, au recrutement de cellules circulantes. En effet, nous décrivons pour la première fois une augmentation significative de l’expression de nombreuses chimiokines par cette muqueuse dès les premiers jours suivant l’infection. En parallèle nous décrivons, dans le sang périphérique, une diminution transitoire du nombre de lymphocytes T CD4+ et CD8+. Enfin, nous avons décelé une augmentation de l’expression d’interleukine 7 (IL-7) après infection. Cette augmentation, spécifiquement observée dans la muqueuse de l’intestin grêle, est corrélée à l’expression des chimiokines. Ces résultats apportent de nouveaux éléments sur la contribution de l’IL-7 dans la régulation de l’expression des chimiokines par la muqueuse intestinale suite à l’infection par le SIV. L’ensemble de nos résultats démontre que la population de lymphocytes T CD4+ de l’intestin grêle est préservée au cours de l’infection aiguë par le SIV chez le macaque rhésus chinois. En parallèle, l’exacerbation de l’expression locale de chimiokines laisse supposer une relocalisation des cellules du système immunitaire vers la muqueuse intestinale. Ces migrations pourraient avoir des effets délétères pour l’hôte en apportant de nouvelles cibles nourrissant la réplication virale. A l’opposé, le recrutement localisé de cellules immunitaires clés pour le déclenchement des réponses antivirales innées et adaptatives pourrait limiter la réplication du virus. Il est donc crucial de mieux définir l’impact de ce recrutement sur l’immunité muqueuse et la progression de la maladie. Nos découvertes apportent également de nouveaux arguments en faveur de l’utilisation du macaque rhésus d’origine chinoise en tant que modèle de choix pour l’étude de la physiopathologie de l’infection humaine par le VIH-1. / As a model to study type 1 human immunodeficiency virus (HIV-1) pathogenesis, rhesus macaques infected with the simian immunodeficiency virus (SIV) are under extensive investigation. Two subspecies of rhesus macaques have been defined, based on a different geographic origin. Indian rhesus macaques exhibit a rapid disease progression and acute infection is characterized by a massive CD4 T-cell loss in the intestinal mucosa. This was associated to the translocation of bacterial products through the gut epithelium during the chronic stage. Contrary to the animals of Indian origin, the pathogenesis of Chinese rhesus macaques infected with SIV is similar to HIV-1 infected patients. Viral and immunological settings in periphery are also closer to what is described in infected humans. However, the kinetics of mucosal disruption is poorly documented in this model. As a first step, I confirmed the rapid SIV dissemination in the gastro-intestinal tract of Chinese rhesus macaques. The small intestine, in particular the ileum, undergoes an early and high viral replication. Despite this high viral load, the numbers of CD4+ T cells in the ileum mucosa remains unchanged during the first two weeks following infection in this model. On the other hand, we noticed a substantial augmentation of cytotoxic T-cell numbers and macrophages, suggesting the establishment in situ of a strong immune response. We demonstrated that this augmentation of CD8+ T cells and macrophages together with the maintenance of helper T-cell numbers in the ileum mucosa are most probably related, at least in part, to the recruitment of circulating cells. Indeed, we describe for the first time a significant augmentation of numerous chemokine expressions by this mucosa the first days post-infection. At the same time, we described a transient diminution of CD4+ and CD8+ T-cell numbers in the blood. Finally, we detected a significant upregulation of interleukine 7 (IL-7) expression after SIV infection. This increase, specifically observed in the small intestine mucosa, is correlated to chemokine expressions. These results highlight new evidences on IL-7 contribution in the regulation of chemokines expression following SIV infection. All together, our results revealed the preservation of CD4+ T cell population in the small intestine mucosa during the acute phase of SIV infection in Chinese rhesus macaques. Furthermore, the exacerbation of local chemokine expressions let us think that immune cells are relocated to the intestinal mucosa the first days after infection. These migrations could have deleterious effects to the host, bringing new targets for viral replication. On the other side, this localized recruitment of immune cells that are key players in intestinal immunity could restrict the replication of the virus. Consequently, it is of major importance to better define the impact of immune cells trafficking on intestinal mucosa integrity and disease progression. Our findings bring new arguments in favor of Chinese rhesus macaque as a suitable model to study HIV-1 pathogenesis.

The impact of rat cytomegalovirus gamma chemokine on dendritic cells

Madela-Mönchinger, Julia Cecilia 19 May 2021 (has links)
Bis heute sind die beiden Ratten-Cytomegalovirus (RCMV)-Isolate RCMV-England (RCMV-E) und RCMV-Berlin (RCMV-B) die einzig bekannten Viren, die ein Homolog von XCL1 kodieren, einem g-Chemokin, das vom Virus kopiert wurde um das Chemokin-Netzwerk des Wirts zu beeinträchtigen. Wie das Wirtshomolog lockt vXCL1 ausschließlich dendritische Zellen (DC) an, die den XC-Chemokinrezeptor 1 (XCR1) exprimieren. In dieser Arbeit wurde untersucht, inwieweit RCMV die XCL1-XCR1-Achse nutzt, um DC zu infizieren und sich im Wirt auszubreiten. In der Ratte konnten zwei DC-Hauptpopulationen identifiziert werden, XCR1+ CD4- und XCR1- CD4+ DC. Es konnte gezeigt werden, dass Überstände von RCMV-infizierten embryonalen Rattenfibroblasten ausschließlich die XCR1+ CD4- Population anlocken. Darüber hinaus konnte nachgewiesen werden, dass RCMV DC infiziert. Durch die Anreicherung wurden DC aktiviert. Während der Infektion inhibierte RCMV die Hochregulation von Reifungsmarkern, einschließlich CD40, CD86 und CCR7. Unabhängig von vXCL1 scheint RCMV die DC-Funktionalität durch das Herunterregulieren von Reifungsgenen zu lähmen. Um die Rolle von XCR1 und die Funktion von vXCL1 in vivo zu analysieren, wurden Xcr1+/+ und Xcr1-/- Ratten mit RCMV-B wt und RCMV-B D-vxcl1 infiziert. Während das XCR1- Expressionsniveau einen Einfluss auf die Geschwindigkeit der RCMV-Verbreitung in den Speicheldrüsen hatte, führte das Fehlen von vXCL1 zu einer starken Abnahme der Virusausbreitung. Die DC-Migration in die Speicheldrüsen war sowohl von vXCL1 als auch von XCR1 abhängig und war reduziert, wenn vXCL1 und XCR1 nicht vorhanden waren. Während der Infektion wurden CD8+ T-Zellen in die Speicheldrüsen rekrutiert. Diese Migration blieb jedoch aus, wenn Xcr1+/+ Ratten mit RCMV-B D-vxcl1 infiziert wurden. Zusammenfassend besitzt RCMV die Fähigkeit DC unabhängig von der vXCL1-Expression zu infizieren. RCMV verwendet vXCL1, um XCR1+ DC anzulocken, was entscheidend für die Virusausbreitung in die Speicheldrüsen zu sein scheint. / To date, the two Rat Cytomegalovirus (RCMV) isolates RCMV-England (RCMV-E) and RCMV-Berlin (RCMV-B) are the only known viruses that encode a homolog of XCL1, a gamma- chemokine adopted by viral piracy to interfere with the host’s chemokine network. Like its host homolog, vXCL1 exclusively attracts dendritic cells (DC) that express the XC chemokine receptor 1 (XCR1). In this work, it was investigated whether RCMV misuses the XCL1-XCR1 axis to infect DC in order to disseminate within the host. Initially, rat DC phenotyping revealed two major DC populations, XCR1+ CD4- DC and XCR1- CD4+. It could be shown that supernatants of RCMV-infected rat embryonic fibroblasts solely attracted the XCR1+ CD4- population. Moreover, RCMV was able to infect and replicate in DC. Due to digestion of the spleen and leukocyte enrichment DC became activated leading to full maturation 24 h after cell isolation. During infection, RCMV inhibited the upregulation of several maturation markers including CD40, CD86 and CCR7 and also led to reduced expression of MHCII, CD4 and XCR1. Regardless of vXCL1, RCMV appears to paralyze DC functionality by downregulating maturation genes. In order to analyze the role of XCR1 and vXCL1 function in vivo, Xcr1+/+ and Xcr1-/- rats were infected with RCMV-B wt and RCMV-B delta-vxcl1. Whereas the XCR1 expression level had an influence on the pace of RCMV-B wt dissemination to the salivary glands, the absence of vXCL1 led to a strong decrease in viral spread. DC migration to the salivary glands was dependent on vXCL1 as well as XCR1 and was markedly reduced when vXCL1 and XCR1 were not present. During infection, CD8+ T cells were recruited to the salivary glands, however, this migration was missing when Xcr1+/+ rats were infected with RCMV-B delta-vxcl1. In conclusion, RCMV has the ability to infect DC regardless of vXCL1 expression. RCMV uses vXCL1 to attract XCR1+ DC which appears to be important for viral dissemination to the salivary glands.

Recherche de nouvelles stratégies thérapeutiques des métastases osseuses : utilisation de la chimiokine CX3CL1 ou de ciments chargés en bisphosphonates / Research of new therapeutic strategies for bone metastases : use of CX3CL1 or bisphosphonate-loaded calcium phosphate cements as new therapeutic tools

Al-Sahlanee, Rasha 28 October 2016 (has links)
Malgré les avancées thérapeutiques récentes, le pronostic des patients porteurs de métastases osseuses (MO) reste faible, ce qui incite à chercher des nouvelles stratégies thérapeutiques. Les chimiokines sont des acteurs majeurs de la réponse immune, et apparaissent comme des cibles potentielles de l’immunothérapie anti-cancéreuse. Nous avons recherché à définir si la chimiokine CX3CL1 pouvait représenter un axe thérapeutique efficace dans le contexte des MO. Pour cela nous avons développé des modèles murins de MO de cancer du rein et du poumon. Dans le modèle de MO de cancer du poumon, notre travail a démontré que l'expression de CX3CL1 inhibe la croissance tumorale. L’analyse transcriptomique des tumeurs a montré que CX3CL1 diminue (i) l’ostéloyse via un effet sur la triade OPG/RANKL/RANK (ii) l'expression de certains checkpoints, en faveur d’une réponse immune antitumorale. En revanche, dans le modèle de MO de cancer du rein, l’expression de CX3CL1 stimule le développement tumoral et l'ostéolyse via une action sur la triade OPG/RANKL/RANK et inhibe la réponse immune antitumorale via une augmentation de l'expression de certains checkpoints immunitaires. Les bisphosphonates (BPs) sont des agents utilisés pour le traitement des MO. Afin de réduire leurs effets indésirables, nous avons utilisé des ciments de phosphate de calcium (CPC), pour délivrer localement dans l’os des BPs (alendronate, ALN). Notre travail a mis en évidence que (i) ces ciments chargés en ALN relarguent en continue les BPs, (ii) le relarguage d’ALN est efficace pour induire des effets cytotoxiques et pro-apoptotiques vis à vis des cellules de cancer du sein / Despite recent therapeutic improvments, the prognosis for a patient with bone metastases (BM) remains poor, this situation prompting the research of new therapeutic strategies. Chemokines are central players in the immune response, and appear as potential targets in anti-cancer immunotherapies. We are interested to determine whether the CX3CL1 chemokine exerted pro or anti-tumor actions within the bone metastatic context. To address this issue, we developed mouse models of lung or renal cancer BM. In lung cancer BM model, our work demonstrated that CX3CL1 expression led to tumor growth inhibition. Tumors transcriptomic analysis revealed that CX3CL1: (i) impacted bone metabolism by modulating the OPG/RANKL/RANK triad (ii) decreased the expression of certain immune checkpoints, this up-regulating the anti-tumor immune response. By contrast, in renal cancer BM model, CX3CL1 expression stimulated bone tumor development and transcriptomic analysis showed that CX3CL1 (i) promoted osteolysis through an action on the OPG/RANKL/RANK triad (ii) -induced tumor development correlated with an increased expression of certain immune checkpoints, this down-regulating the anti-tumor immune response. Bisphosphonates (BPs) are targeted agents used for BM treatment. In order to reduce their side effects, we used resorbable calcium phosphate cements (CPC), which are frequently used as bone void fillers, as platform for a local delivery of BPs (alendronate, ALN). As a whole, our in vitro data demonstrated that: (i) ALN-CPC cements continuous released ALN; (ii) this ALN release was effective in inducing cytotoxic and pro-apoptotic effects in breast cancer cells

Inebriated Immunity: Alcohol Affects Innate Immune Signaling in the Gut-Liver-Brain Axis

Lowe, Patrick P. 18 July 2018 (has links)
Alcohol is a commonly consumed beverage, a drug of abuse and an important molecule affecting nearly every organ-system in the body. This project seeks to investigate the interplay between alcohol’s effects on critical organ-systems making up gut-liver-brain axis. Alcohol initially interacts with the gastrointestinal tract. Our research describes the alterations seen in intestinal microbiota following alcohol consumption in an acute-on-chronic model of alcoholic hepatitis and indicates that reducing intestinal bacteria using antibiotics protects from alcohol-induced intestinal cytokine expression, alcoholic liver disease and from inflammation in the brain. Alcohol-induced liver injury can occur due to direct hepatocyte metabolic dysregulation and from leakage of bacterial products from the intestine that initiates an immune response. Here, we will highlight the importance of this immune response, focusing on the role of infiltrating immune cells in human patients with alcoholic hepatitis and alcoholic cirrhosis. Using a small molecule inhibitor of CCR2/CCR5 chemokine receptor signaling in mice, we can protect the liver from damage and alcohol-induced inflammation. In the brain, we observe that chronic alcohol leads to the infiltration of macrophages in a region-specific manner. CCR2/CCR5 inhibition reduced macrophage infiltration, alcohol-induced inflammation and microglial changes. We also report that chronic alcohol shifts excitatory/inhibitory synapses in the hippocampus, possibly through complement-mediated remodeling. Finally, we show that anti-inflammasome inhibitors altered behavior by reducing alcohol consumption in female mice. Together, these data advance our understanding of the gut-liver-brain axis in alcoholism and suggest novel avenues of therapeutic intervention to inhibit organ pathology associated with alcohol consumption and reduce drinking.
