Full textThe end of the Manila Galleon was a highly influential event for East Asian economy. The activities of the then declining Spanish Royal Philippine Company were deeply affected by such event: the Company was deprived, mainly in its factories in Calcutta and Canton, of one of its most important assets, namely the access to Latin American silver. Thus, the Company’s employees redirected their private activities towards the then booming opium business, with the financial support of Manila investors. This study identifies and analyses these activities, which are in the roots of what later became Jardine, Matheson & Co., and places them in the context of the European trade in Asia, to which the Spanish undoubtedly made a very important contribution in an key period of the opium economy and modern China historical development.

Full textHost specialization and host-race formation may be key processes in maintaining and generating diversity within parasite populations. The objective of this thesis was to analyze these processes in the seabird tick Ixodes uriae, a common and widely distributed ectoparasite that exploits a great diversity of seabird host species, to better understand the relative role of host-related constraints and geographic factors in its evolution and diversification. I addressed this question using different approaches, including population genetic and phylogeographic analyses, morphometry and field experimentation. Results show that the spatial factor is a key component in shaping the diversity of I. uriae, as four geographical genetically isolated groups exist within the global distribution of this parasite. The formation of host races is also a general process in the evolution of I. uriae, but has evolved to different degrees in different geographical regions. Host preference in the tick, along with mechanical or physiological host-related constraints (e.g., beak morphology, blood digestion, immune response) are likely involved in the evolution of I. uriae host races. Overall, results fall in line with the geographic mosaic theory of evolution that predicts that the outcome of species interactions can vary across geographic landscapes, highlighting the role played by ecological characteristics of the host in the diversification of I. uriae. Given results to date, host specialization may be a common process in tick systems and thus may have strong epidemiological and evolutionary implications for the pathogens that they transmit

Full textMany studies have been devoted to understanding the origin of life's vast diversity. In parasitic organisms, host specialization may be a key process in the emergence and maintenance of this diversity. Host and parasite life history traits can shape the spatial and temporal patterns of genetic variation, and thus, the possibility of host-associated divergence. In this thesis, we examine the evolution of host specialization in two host/parasite systems involving tick vectors of Lyme borreliosis: Ixodes uriae, a tick that exploits colonial seabirds in polar regions and, Ixodes ricinus, a tick with a large spectrum of terrestrial hosts in Europe. These congeneric species share many traits, but differ noticeably by the characteristics of the hosts they exploit and the strategies they use to encounter these hosts. Based on the basic biology of these ticks, we have formulated several hypotheses concerning the distribution of their genetic variation in natural populations and particularly among their local hosts. Ticks were sampled across a large spatial scale and were characterized using microsatellite and mitochondrial markers. We analyzed this data using different statistical tools frequently employed in phylogeography and population genetics, including some recently developed methods. Taken as a whole, our results support a scenario of recent and recurrent evolution of host races in I. Uriae, where the local outcome of the interaction varies in space and among host species. Our results also suggest the existence of races specialized on different host types within I. Ricinus populations (birds, rodents, lizards, etc), and a potential mechanism for assortative mating in these races. Overall, the work presented in this thesis highlights the importance of parasitic traits for the diversification process (dispersal, host encounter strategies, mate pair formation). More specifically, the frequent evolution of specific host races within tick populations will have importance consequences for the circulation of the pathogens they carry and, as such, calls into question our current understanding of the epidemiology of tick-borne diseases such as Lyme borreliosis

Full textTaking into account the ecological context of host parasite interactions may be important to consider when examining trade offs between immune responses and the other needs of the organism. Ecological factors likely to affect exposure risk and the response to parasitism will ultimately affect the dynamics of biodiversity in host-parasite systems. Taking these aspects into account is thus necessary in order to define adequate public health policies and epidemiological risk models

Full textCutaneous neurogenic inflammation (CNI) is an inflammation of the skin induced by the activation of intraepidermal nerve fibers that release neuropeptides such as substance P (SP). CNI is involved in pruritic inflammatory skin disorders such as psoriasis, atopic dermatitis (AD) and Netherton syndrome (NS). A new concept is growing, suggesting that keratinocytes could also trigger INC. The proteases activated receptor 2 (PAR-2) is strongly incriminated in CNI associated with these dermatoses, which allow to understand the histamine-independent itching pathways. The therapeutic stakes are high since there is currently no effective treatment allowing the specific management of histamine-independent pruritus during skin disorders associated with CNI.Although the role of PAR-2 in the secretion of neuropeptides from sensory neurons is clearly established, its involvement in the modulation of genes involved in the maintenance or amplification of CNI remains unknown. The inflammatory role of PAR-2 on keratinocytes has also been demonstrated through the production of cytokines in a Ca2+-dependent mechanisms. The overexpression of PAR-2 and the loss of ORAI1 expression, a calcium channel following keratinocytes differentiation suggest different signaling pathways downstream to PAR-2 activation between undifferentiated and differentiated keratinocytes.In order to study the pro-inflammatory role of PAR-2 during pruritic dermatoses, we analyzed the effect of its activation on rat primary sensory neurons from dorsal spinal ganglia (DRG) and on differentiated human primary keratinocytes (DhPK) by screening the expression of inflammatory mediators. To deepen the Ca2+ pathways underlying PAR-2-mediated inflammatory mediator modulation in DhPK, we performed Ca2+ imaging experiments and different antagonists were used to analyze the involvement of intracellular actors. In a partnership with the dermatological laboratories of Uriage, we tested the effects of Uriage thermal water on PAR-2-induced gene modulation in DhPK. We also used a PC12 cell line differentiable in neurons by the NGF in order to use them as alternatives of rat primary sensory neurons from DRG for the study of INC. We also used a PC12 cell line differentiable in neurons by the NGF use them as alternatives of rat primary sensory neurons from DRG for the study of INC.The results obtained during the screening of the PAR-2-modulated genes confirmed the proinflammatory role of PAR-2 in rat primary sensory neurons and in DhPK. The discovery of a new PAR-2-mediated Ca2+ pathway in DhPK offers new therapeutic pathways for pruritic dermatoses such as psoriasis, AD and NS. The results obtained with the thermal water of Uriage can present a therapeutic perspective for patients suffering from pruritic dermatoses refractory to conventional treatments. The use of a neuronal cell line as the PC12 for the study of INC would be an useful alternative in the development of cosmetic tests
