This thesis presents an approach to modelling dynamic mass capture which is applied to a number of system models. The models range from a simple 2D Euler-Bernoulli beam with point masses for the end-effector and target to a 3D Timoshenko beam model (including torsion) with rigid bodies for the end-effector and target. In addition, new models for torsion, as well as software to derive the finite element equations from first principles were developed to support the modelling. Results of the models are compared to a simple experiment as done by Ben Rhody. Investigations of offset capture are done by simulation to show why one would consider using a 3D model that includes torsion. These problems have relevance to both terrestrial robots and to space based robotic systems such as the manipulators on the International Space Station capturing payloads such as the SpaceX Dragon capsule. One could increase production in an industrial environment if industrial robots could pick up items without having to establish a zero relative velocity between the end effector and the item. To have a robot acquire its payload in this way would introduce system dynamics that could lead to the necessity of modelling a previously ‘rigid’ robot as flexible.

Centro de Pesquisas Gonçalo Moniz. Salvador, Bahia, Brasil / Foi anteriormente demonstrado que as células NK (Natural Killer) estão relacionadas às bases para resistência à infecção por Trypanosoma cruzi, pois a depleção de células positivas para NK1.1+ resulta em alta parasitemia de camundongos C57BI/6 infectados pelo T. cruzi. Estudos de nossa equipe indicaram ainda que as células T NKH-t- poderiam induzir a formação de células T efetoras/nnemória, e que a resistência à infecção foi correlacionada com a quantidade de células T CD4-<- CD45RB"®^ presentes antes da infecção. No presente estudo avaliamos a função regulatória de células T NK1.1+ durante a infecção experimental pelo T. cmzi, na ausência de linfócitos B. Utilizamos os seguintes animais: C57BI/6 controles, ^MT C57BI/6, nMT reconstituídos (com células B de C57BI/6 ou B de C67BI/6 IL-10KO) ou tratados com imunoglobulinas. Neste modelo experimental, observamos que os animais p.MT apresentaram menores números de células T efetoras/memória no baço comparados aos controles (C57BI/6), na fase aguda de infecção. A reconstituição com células B ou o tratamento com Ig em animais ^iMT infectados resultou em aumento de células T efetoras/memória, comparado ao controle (jiMT infectado). Da mesma maneira e até fase crônica de infecção, a transferência adotiva de células B em animais ^MT causa persistência de células T efetoras/memória no baço. Como a molécula de CD1 (encontrada sobre células B e dendríticas) é reconhecida por células NK1.1, a expressão desta molécula foi também avaliada durante a infecção. Após a infecção, houve diminuição de células CD1+ no baço de animais C57BI/6, e ausência destas células nos jxMT. A recuperação desta população celular no baço de {aMT infectados após reconstituição com linfócitos B foi concomitante á reposição de células T CD4+ NK1.1 no músculo esquelético destes mesmos animais. Houve ainda aumento de CD4+NK1.1 também no músculo esquelético dos animais ^MT reconstituídos com linfócitos B provenientes de C57BI/6 IL-10KO. De modo interessante, a depleção de NK1.1 durante a fase crônica, causou aumento de células T efetoras/memória encontradas no músculo esquelético de animais |uMT. Esses resultados estão relacionados aos dados de histopatologia, onde foi evidenciado maior infiltrado inflamatória no tecido HfKiscular de animais fxMT tratados com anti-NK1.1, durante a fase crônica da infecção. Nossos resultados indicam desse modo que a presença da célula B estaria ligada à formação de células T CD45RB"^ na fase aguda e manutenção/aumento de memória imune na fase crônica de infecção, conferindo ao grupo de animais reconstituídos com células 6, maior sobrevida. Sugere-se, portanto que as células T CD4+ NK1.1+ poderiam ser regulatórias no sentido de apresentar atividade antiinflamatória e que as células aP+NK1.1+ exerceriam função auxiliar na geração de células T efetoras/memória em nosso sistema experimental. / We have previously demonstrated that NK (Natural Killer) cells have been related to resistance to T. cruzi infection and the depletion of NK1.1+ cells resulted in high mortality and increased parasitemia in C57BI/6 Infected mice. Recently, we suggested that the NK1.1 T cells were involved on memory T cell generation, and resistance to infection was correlated with increased numbers of 004^“'*''^ CD45RB"®^®“'^ T cells, present before infection. In this study we evaluated the regulatory function of NK1.1+ T cells during 7. cruzi infection in ^iMT C57BI/6 infected mice. The following mice were used; C57BI/6, ^MT C57BI/6 and nMT C57BI/6 Imunoglobulin (lg)-treated or adoptively transferred with B cells (obtained from C57BI/6 or from C57BI/6 IL-10KO). In this experimental model. yMT infected mice have show decreased numbers of effector memory T cells, compared to C57BI/6 infected controls, during acute infection. The adoptive transfer of B cells or the treatment with immunoglobulins (Igs), induced increased numbers of effector memory splenic T cells, compared to C57BI/6 controls. Furthermore, Ig administration to p,MT uninfected mice is able to increase ap+NK1.1+ splenic cell population. As NK1.1 cells recc^nize C01 molecule which is expressed on B and dendritic cells, CD1 expression was evaluated in spleens of nMT and C57BI/6 mice to estimate whether the expression of CD1 was modified after infection. When compared to uninfected controls, CD1-presenting cells decreased from both nMT and C57BI/6 mice and were increased following B cell-transfer to laMT recipient mice. Interestingly, the depletion of NK1.1 cells also increased effector memory T cells found on skeletal muscles infiltrates from jiMT, and this was correlated to the increased inflammatory response found in these ^iMT NK1.1-depleted mice, during the chronic phase of infection. In this inflammatory compartment, ^iMT infected mice presented low numbers of CD4+NK1.1 T cells, when compared to C67BI/6. Previous observations from our laboratory suggest that CD4+NK1.1+ T cells (which are decreased in skeletal muscle from infected laMT mice), may be related to the enhanced inflammatory response during the early chronic infection. Finally, these studies suggest that CD4+NK1.1+ T cells may be regulatory with an antiinflammatory activity and that ap+NK1.1+ T cells may be involved on effector memory T cell-generation in our experimental system.

Os neutrófilos são os leucócitos circulantes mais abundantes. Apesar de serem importantes no combate às infecções, o intenso recrutamento e a consequente ativação dessas células levam à liberação de mediadores inflamatórios que estão relacionados com o agravamento do quadro clínico de inúmeras doenças. Dessa forma, nos últimos anos tem-se intensificado a procura por substâncias terapêuticas que minimizem os danos teciduais ocasionados pela infiltração neutrofílica. Estudos prévios do grupo de pesquisa mostraram que as 3-fenilcumarinas, que constituem uma classe de produtos naturais de origem vegetal, são substâncias promissoras como moduladores do metabolismo oxidativo de neutrófilos. Em continuidade a essas investigações, o derivado sintético 3-fenilcumarínico 6,7-diidroxi-3-[3\',4\'- metilenodioxifenil]-cumarina (C13) foi selecionado, por apresentar o grupo substituinte ortodiidroxi nas posições C-6 e C-7 do esqueleto cumarínico e a metilenodioxila ligada ao anel fenílico, no intuito de avaliar o seu efeito nas demais funções efetoras dos neutrófilos, como também em um modelo animal de inflamação articular. Foi avaliado o efeito modulatório in vitro da C13 sobre a quimiotaxia, a produção de ERO e interação com o sítio ativo da mieloperoxidase (MPO), a fagocitose de imunocomplexos (IC), a desgranulação da enzima elastase, a atividade microbicida sobre Candida albicans, a mobilização e o influxo de cálcio, a polimerização do citoesqueleto, e a formação e liberação das NETs em neutrófilos humanos. A C13 inibiu, de forma dependente da concentração, o metabolismo oxidativo de neutrófilos estimulados via receptores de IgG (Fc?R) e/ou de complemento (CR), utilizando-se diferentes tipos de IC e foi capaz de interagir com o sítio ativo da MPO. Nas concentrações próximas da necessária para inibir 50% do metabolismo oxidativo (~ 2µmol/L), a C13 não interferiu nas demais funções efetoras dos neutrófilos avaliadas. No entanto, na maior concentração avaliada (20 µmol/L), a C13 inibiu cerca de: 30% da capacidade das células de migrar a favor dos agentes quimiotáticos n-formil-metionil-leucil-fenilalanina (fMLP) e leucotrieno B4; 70% da fagocitose de IC mediada por CR; 40% e 80% da desgranulação estimulada por fMLP e IC imobilizados, respectivamente; 50% do processo de formação e liberação das NETs. Esta concentração de C13 também interferiu na polimerização do citoesqueleto de actina, mas não inibiu: a quimiotaxia de neutrófilos frente à interleucina (IL) 8; a capacidade fagocítica de IC estimulada via Fc?R e Fc?R+CR; e a atividade microbicida sobre C. albicans. Na segunda parte deste trabalho, foi avaliada a toxicidade da C13 sobre neutrófilos mantidos em condições de cultura celular por 6 e 12 h. Nos períodos avaliados, essa substância não alterou a viabilidade dos neutrófilos. Por último, a C13 foi incorporada em vesículas lipossomais e sua atividade biológica foi avaliada em ratos Wistar com inflamação articular induzida por zimosan. O tratamento dos animais com a C13 lipossomal (1mg/Kg) reduziu a formação do edema e a infiltração de leucócitos e neutrófilos na sinóvia inflamada, mas não alterou a concentração sinovial das citocinas inflamatórias fator de necrose tumoral ?, IL-1? e IL-6. Portanto, o derivado 3-fenilcumarínico C13 pode servir de protótipo para o desenvolvimento de novos agentes terapêuticos com aplicação no tratamento de doenças onde há intensa participação dos neutrófilos. / Neutrophils are the most abundant circulating leukocytes. Although neutrophils are important to fight against infections, the massive recruitment and consequent activation of these cells result in the release of inflammatory mediators that are associated with worsening of the clinical condition in many diseases. In this sense, the search for new therapeutic compounds that minimize tissue damage caused by neutrophil infiltration has been intensified in the past few years. Previous studies have demonstrated that 3-phenylcoumarins, a class of plantderived natural compounds, are promising modulators of neutrophil oxidative metabolism. To continue these investigations, we selected the 3-phenylcoumarin derivative 6,7-dihydroxy-3- [3?,4?-methylenedioxyphenyl]-coumarin (C13), bearing the 6,7-dihydroxyl and the 3?,4?- methylenedioxyl groups, to further assess its effects on the other effector functions of neutrophils, as well as on in an animal model of articular inflammation. We examined the in vitro modulator effect of C13 on the human neutrophil chemotaxis, production of ROS and interaction with active site of myeloperoxidase (MPO), phagocytosis of immune complexes (IC), degranulation, killing of Candida albicans, calcium mobilization and influx, cytoskeleton polymerization, and the formation and release of NETs. C13 inhibited, in a concentration-dependent manner, the neutrophil ROS generation elicited via IgG (Fc?R) and/ or complement (CR) receptors using different types of IC and it interacted with active site of MPO. At concentrations near to that required to suppress the ROS production by 50% (~ 2µmol/L), C13 did not modulate the other neutrophil effector functions assessed. However, at the highest concentration tested (20 µmol/L), C13 inhibited nearly: 30% of the cell ability to migrate towards n-formyl-methionyl-leucyl-phenylalanine (fMLP) and leukotriene B4; 70% of CR-mediated phagocytosis of IC; 40% and 80% of cell degranulation triggered by fMLP and immobilized IC, respectively; and 50% of the NETs formation and release process. Such C13 concentration also interfered in the actin cytoskeleton polymerization, but it did not suppress the neutrophil: chemotaxis towards interleukin (IL) 8; capacity to phagocytose IC elicited via Fc?R and Fc?R+CR; and killing of C. albicans. In the second part of this study, we examined whether C13 was toxic towards neutrophils maintained in culture for 6 and 12 h. At the time points assessed, this compound did not change the viability of neutrophils. Finally, we incorporated C13 into liposomes and examined its biological activity in Wistar rats of zymosan-induced articular inflammation. Treatment of animals with liposomal C13 reduced edema formation, and leukocyte and neutrophil infiltration in the inflamed synovia, but it did not change the synovial concentration of the inflammatory cytokines tumor necrosis factor ?, IL-1?, and IL-6. Therefore, the 3-phenylcoumarin derivative C13 can be a prototype for the development of novel therapeutic agents to be used in the treatment of diseases where neutrophils have intense participation.

Les lymphocytes T CD8 ont un rôle essentiel dans la protection contre les agents pathogènes intracellulaires et la progression tumorale. Ainsi, la compréhension de la diversité des mécanismes de différenciation des lymphocytes T CD8 naïfs en cellules effectrices, ainsi qu’en cellules mémoires compétentes, est fondamentale pour le développement efficace de vaccins à cellules T. Dans ce travail de thèse, nous avons abordé deux questions centrales : (1)Très tôt après l’activation des cellules T CD8, quels sont les mécanismes par lesquels les cellules T effectrices agissent comme effecteurs pro-inflammatoires en recrutant d’autres cellules? Et quel est leur rôle dans la réponse immunitaire? (2) Quel est le rôle du contexte infectieux dans le programme de différenciation des lymphocytes T CD8 ? Est-il responsable de l’hétérogénéité des cellules répondeuses et a-t-il un rôle dans les différents effets protecteurs des cellules mémoires? Afin de répondre à ces questions, nous avons choisit d’utiliser des cellules T CD8 exprimant un récepteur pour l’antigène transgéniques (TCR-Tg) pour suivre la différentiation in vivo des lymphocytes T CD8. De plus, la méthode de RT-PCR sur des séries de cellules uniques, nous a permis d’analyser la co-expression des ARNm dans ces cellules. Comme l’utilisation à haute fréquence de cellules TCR-Tg a été fortement critiquée, nous avons comparé la différenciation de ces cellules avec celle des cellules endogènes (non transgéniques et rares). Dans ce premier manuscrit nous avons observé un comportement similaire, ce qui a renforcé l'avantage d'utiliser des cellules TCR Tg pour étudier les réponses immunitaires des lymphocytes T CD8. De plus, nous avons conclu que la diversité des réponses immunitaires des lymphocytes T CD8 n’est pas conditionnée par la fréquence de cellules naïves. Dans un deuxième manuscrit, nous avons comparé la réponse des cellules OT1 TCR-Tg (spécifiques de l’antigène OVA) à l'infection bactérienne LM-OVA (Listeria Monocytogènes exprimant OVA) avec la réponse des cellules P14 TCR-Tg (spécifiques de l’épitope GP33) à l’infection par le virus LCMV. Nous avons montré que les cellules OT1, stimulées par l’OVA dans un contexte bactérien (LM-OVA), présentent un profil d’expression génique distinct de celui des cellules P14 stimulées par le GP33 dans un contexte viral (LCMV). Nous avons également co-stimulé les cellules P14 et OT1 dans une même souris suivant le même contexte bactérien avec LM-GP33 et LM-OVA. Dans ce cas, nous n’avons pas observé de différence dans le profil d’expression génique. L’ensemble des résultats démontrent que les stimulations spécifiques des cellules T CD8 par différents agents pathogènes génèrent des cellules T CD8 présentant des caractéristiques différentes qui ne sont pas déterminées par la spécificité du TCR mais plutôt par le contexte infectieux. De plus, nous avons montré que les cellules mémoires endogènes résultant de la stimulation des CD8 en présence de LCMV ont été plus efficaces après une deuxième réponse immunitaire que des cellules mémoires générées après stimulation avec LM-GP33 (bactérie). Nous avons également observé que la protection plus efficace dans le contexte viral est associée à des cellules T CD8 qui présentent un phénotype de cellules T mémoires effectrices (TEM) tandis que les cellules T CD8 générées dans un contexte bactérien ont plutôt un phénotype associé aux cellules T mémoires centrales (TCM). Ces résultats démontrent que différents pathogènes induisent différents profils de différentiation des cellules T CD8 et que malgré l’élimination efficace des différents pathogènes dans une réponse primaire, la qualité des cellules mémoires générées au cours de cette réponse peut être différente. Dans un troisième manuscrit, nous avons étudié les mécanismes de recrutement d’autres cellules par les lymphocytes T CD8 activés à un temps précoce de la réponse immunitaire. (...) / CD8 T cells are essential for the elimination of intracellular pathogens and tumor cells. Understanding how naïve CD8 T cells differentiate into effector cells capable of eliminating pathogens and to generate adequate memory cells during immune responses is fundamental for optimal T cell vaccine design. In this PhD thesis work we addressed two central questions: 1) What are the mechanisms by which early effector T cells could act as pro-inflammatory effectors? And what is their role in the immune response? 2) How heterogeneous are CD8 responses? Could different pathogens modulate CD8 T cell differentiation programs and be responsible for CD8 cell-to-cell heterogeneity? Could they also generate memory cells with different protection capacities? To address these questions related to the diversity of CD8 T cell differentiation during immune responses, we used the single cell RT-PCR technique to detect ex vivo expression of mRNA in each individual cell, and Brefeldin A injected mice to detect ex vivo intracellular proteins. As experimental system to evaluate in vivo cell activation we used T cell receptor transgenic (TCR-Tg) CD8 T cells. Since the use of TCR-Tg cells to study immune responses has been subjected to criticism (due to high frequency of naïve-precursor transfers), in a first Ms. we compared the behavior of TCR-Tg and endogenous (non-transgenic and present at low frequency) cells in the same mouse. We found fully overlapping behavior between these two cell populations, which reinforced the advantage of using TCR-Tg cells to study CD8 immune responses. In addition, we concluded that the frequency of naïve-precursors do not induce diversity on CD8 T cell differentiation patterns. In a second Ms. we evaluated the impact of different pathogens in the diversity of CD8 T cell properties during two different immune responses: OT1 TCR-Tg cells (specific for OVA antigen) in the response to LM-OVA (Listeria Monocytogenes expressing OVA) infection; and P14 TCR-Tg cells (specific for GP33 epitope) in the response to Lymphocytic choriomeningitis vírus (LCMV) infection. We found that OT1 and P14 cells had different properties. As this difference could also be attributed to the different TCR avidity between OT1 and P14 cells, we then compared the behavior of P14 and OT-1 cells in the same mouse, co-injected with LM-OVA and LM-GP33. Since no differences were then detected, these results demonstrated that priming with different pathogens generates CD8 T cells with different characteristics that are not determined by TCR usage, but rather by the infection context. In addition, when looking for the protection capacity of endogenous CD8 memory cells generated in bacterial or viral context, we found that memory cells generated after LCMV priming were more efficient in responding to a second challenge, than memory cells generated after LM-GP33 priming. We also found that this better protection is associated with a T cell effector memory (TEM) phenotype associated with the LCMV infection, in contrast with a T cell central memory (TCM) phenotype generated after LM-OVA infection. These results demonstrate that different pathogens are responsible for diversity of CD8 T cell differentiation patterns and that even when distinct pathogens are efficiently eliminated during the primary immune response the quality of the memory generated may differ. In a third Ms. we studied the mechanisms by which effector CD8 T cells attracted other cell types in the early days of an immune response. We used two experimental systems: the response of OT1 TCR-Tg cells to LM-OVA infection; and the response of anti-HY TCR-Tg cells to male cells (“sterile”-non infectious context). In both cases we found that immediately after activation, CD8 T cells expressed high levels of pro-inflammatory cytokines and chemokines (such as TNFα, XCL1, CCL3 and CCL4). (...)

Les Cellules Dendritiques sont un groupe hétérogène de cellules présentatrices d’antigènes, importantes pour le contrôle des réponses innées et adaptatives. Les Cellules Dendritiques Plasmacytoïdes (pCD) en représentent une population unique, aux caractéristiques phénotypiques et fonctionnelles particulières, notamment par leur capacité à produire de grande quantité d’Interféron de type I (IFN). Cette signature IFN marque la physiopathologie du Lupus Erythémateux Systémique (LES), maladie auto-immune systémique. Les mécanismes à l’origine de cette production excessive d’IFN par les pCD restent incomplètement élucidés. Nous montrons, dans notre étude, chez l’homme comme dans un modèle murin que les plaquettes, activées dans le LES, participent à la production d’IFN via le CD40L. Cette production en excès d’IFN, a pour conséquence une maturation et activation d’autres Cellules Dendritiques (CD) entrainant l’activation inappropriée des lymphocytes T. Chez le sujet sain, cette activation inappropriée du système immunitaire adaptatif doit être strictement contrôlée afin d’assurer l’homéostasie du système immunitaire. Il a été montré précédemment que de nombreux lymphocytes aux caractéristiques phénotypiques de type mémoire-effecteur (TEM) peuplent les tissus périphériques, notamment le tissu cutané. Ces TEM sont capables de s’activer et proliférer localement en réponse à un stimulus. Les Cellules de Langerhans (LC) sont des cellules dendritiques résidant au niveau cutané dans l’épiderme. Leur fonction est à ce jour l’objet d’une controverse entre une fonction immuno-stimulante (modèle humain) et une fonction immuno-régulatrice (modèle murin). Nous démontrons dans cette étude que les LC, à l’état basal, chez l’homme, induisent la prolifération de Lymphocytes T régulateurs (Treg) au niveau cutané, capables de bloquer la stimulation inappropriée des TEM cutanés. Cependant en présence d’un stimulus infectieux, les LC induisent préférentiellement la prolifération des TEM en limitant celle des Treg. Les LC semblent être à la fois immuno-régulatrices ou stimulantes en fonction du contexte biologique auquel elles sont confrontées. / Dendritic Cell (DC) are a heterogeneous group of antigen-presenting leukocytes that are important in activation of both the innate and adaptative arms of the immune system. Plasmacytoid Dendritic Cells (pDC) represent a unique population, characterized by their ability to produce large amounts of type I Interferon (IFN). This « IFN signature » is a prominent feature of Systemic Lupus disease (SLE). Mechanisms leading to the excessive production of type I IFN remain largely unknown. Here, in our present study, we demonstrate that platelets are activated in SLE patients by circulating immune complexes and represent a major reservoir of CD40L. Activated platelets potentiate the production of type I IFN by pCD through a CD40L/CD40 interaction. Excessive production of type I IFN by pCD leads to DC activation and maturation and inappropriate activation of auto-reactive T cells.Under steady state condition, inappropriate activation of the immune system must be tightly controlled. It has been previously shown that normal adult human skin contains a large number of resident T cells (TRM) expressing the phenotype of Effector Memory T cells (TEM). These TEMTRM are specific for antigens previously encountered through skin and can be activated and proliferate under specific stimulation. Langerhans Cells (LC) are a group of skin resident DC living in epidermis. There is currently substantial controversy regarding the physiologic role of LC with regard to immunoregulation versus immunostimulation. Here we show that under steady state condition, LC induce the proliferation of a small subset of TRM. These proliferating TRM express the phenotype of TREG and are functional. However this stimulation of TREG could be reversed in the presence of foreign antigen in a dose-dependant fashion, as the addition of a pathogen to LC and TRM led to diminished TREG proliferation and increased TEM proliferation. These findings establish a novel immunological role for LC in human skin, allowing for the constitutive maintenance of tolerance, while also permitting the stimulation of resident immune memory in response to infectious challenge
