Full textTo identify key molecules involved in the compatibility polymorphism in the Schistosoma mansoni / Biomphalaria glabrata model, we developed a comparative proteomics approach for the larval stages that interact with the invertebrate host. The qualitative and quantitative comparison of the proteomes of compatible and incompatible parasite strains led to the identification of a new family of schistosome antigens that share molecular characteristics with highly glycosylated secreted mucins. In particular, they possess a domain containing a variable number of tandem repeats (VNTR). These proteins are (i) only expressed in larval stages interacting with the mollusc, (ii) located in the apical gland of miracidia and sporocysts and (iii) secreted and released in excretion-secretion products. Moreover, we show that these mucin-like proteins display a high degree of polymorphism and that extensive differences are observed between S. Mansoni strains. These different characteristics led us to name this novel molecular family “S. Mansoni Polymorphic Mucins” SmPoMuc. Next, we show that SmPoMuc are coded by a multi-gene family that evolve following the model of “birth and death”. SmPoMuc genes are transcribed in an individual-specific manner, and for each gene, multiple splice variants exist. The incidence of this polymorphism on SmPoMuc glycosylation status was demonstrated. Our data support the view that S. Mansoni has evolved a complex cascade of mechanisms – a “controlled chaos” – based on a relatively low number of genes that provides highly polymorphism to SmPoMuc

Full textThe coevolutionary dynamic playing in the host-parasite interaction leads to an arms race between host and parasite. In certain models, this arms race results in a compatibility polymorphism for which the molecular bases remain largely unknown. The aim of this PhD thesis was to identify the molecular determinants of the compatibility polymorphism that exists in the Biomphalaria glabrata/Schistosoma mansoni interaction. First, we developed a comparative proteomics approach between compatible and incompatible strains of the parasite. This approach allows us to identify molecules that could play a key role in this interaction. They consist in highly polymorphic mucin-like proteins, the « Schistosoma mansoni Polymorphic Mucin » (SmPoMucs), and scavengers of reactive oxygen species (ROS scavengers). In order to study more completely the arms race that takes place in the B. Glabrata/S. Mansoni interaction, we investigate the molluscan counterparts of these molecules. Co-precipitation approaches allow us to show that SmPoMucs interact with diversified immune receptors from the mollusk, the Fibrinogen-related Proteins (FREPs). This is the first evidence of the interaction between an individual repertoire of polymorphic potential parasite antigens (SmPoMucs) and an individual repertoire of diversified potential immune receptors (FREPs) from an invertebrate host. We found a third partner associated with FREPs and SmPoMucs, a thioester-containing Protein (TEP). TEP belongs to a class of molecules involved in the phagocytosis or in encapsulation. The presence of TEP in this immune complex argues in favor of the involvement of the formed complex in parasite immune recognition and elimination. We are also interested in the effector mechanisms responsible for the destruction of the parasite, in B. Glabrata they rely essentially on the production of Reactive Oxygen Species (ROS). We show that a phenotypic concordance exists between the levels of host ROS production and parasite ROS scavengers’ production. The compatibility polymorphism in the B. Glabrata/S. Mansoni interaction seems to be based on the confrontation of polymorphic and/or diversified molecules concerning immune recognition mechanisms and on quantitative reciprocal adaptations concerning immune effector mechanisms

Full textLes anticorps anti-BgSel reconnaissent spécifiquement un composant de 79 kDa sécrète par les cellules Bge ; cette molécule représenterait la forme glycosylée de BgSel. L'expression de BgSel est influencée par les produits parasitaires. Certains travaux préliminaires semble indiquer que BgSel reconnaîtrait un composant de la membrane des sporocystes. Parallèlement, nous avons mis en évidence la présence du trisaccharide Lewis x (Le x) en surface des miracidiums et sporocystes de S. Mansoni. Les sélectines et le déterminant Le x forment un système récepteur-ligand chez les mammifères, implique notamment dans l'interaction entre cellules immunes de l'hôte définitif (homme) et schistosome. Le fucoïdan, polysaccharide connu pour inhiber les fonctions d'adhérence des sélectines, inhibe l'interaction entre les cellules Bge et les sporocystes de S. Mansoni. De plus, BgSel semble reconnaître spécifiquement le fucoïdan. L'ensemble de ces résultats permet d'envisager l'existence d'un système équivalent au système sélectine-Le x de vertébrés, BgSel-Le x, dans l'interaction entre cellules de mollusques et larves de schistosome

La recherche d'un promoteur homologue a ete entreprise. L'adnc de l'actine non musculaire de b. Glabrata a ete clone et utilise comme sonde pour isoler son promoteur. Aucun element transposable n'ayant encore ete identifie dans le genome du gasteropode, nous avons teste, sans succes, la mobilite de 2 transposons d'insectes (hobo de d. Melanogaster et hermes de m. Domestica) dans les cellules bge. Par une strategie pcr et a l'aide d'amorces derivees du transposon mariner, une sequence presentant une faible homologie avec les sequences de mariner de d. Tigrina (planaire) et c. Elegans (nematode) a ete isolee qui correspond probablement a un vestige de transposase. Sur la base de ces resultats, la caracterisation d'un element transposable chez b. Glabrata est envisageable
