Full textRed blood cell egress and invasion by Plasmodium merozoites are crucial steps of the parasite life cycle, orchestrated by a cascade of proteases. Among these, the subtilisin SUB1, a Plasmodium serine protease, plays a prominent role. Its properties - accessible, essential and different from the host enzymes- qualify it as an interesting drug target. The objectives of this work were to select SUB1 inhibitors and to better understand its auto-activation process thanks to the resolution of its tridimensional structure. Following an in silico screening performed on P. Vivax-SUB1 3D-structural models, a first generation of SUB1s inhibitors has been selected. The best compound has been validated on the Pv/Pf/PbSUB1recombinant enzymes, on in vitro cultures of P. Falciparum and on P. Berghei in vivo growth in mice. A structure-activity relationship study is in progress in order to improve the potency of this inhibitor. To support this optimisation phase, we have resolved the 3D-structure of the Pv and PfSUB1 enzymes. The analysis of the SUB1 3D structures reveals the existence of a new domain, which does not exist in other known subtilisins. Using biochemical and genetic approaches, we have shown that this domain plays an important role in the regulation of SUB1 enzyme activity in vitro and in vivo. These data provide novel important insights into Plasmodium subtilisins. We now capitalize on these results to design an inhibitor with increased potency and complying with the properties of a novel antimalarial candidate

Full textThe thesis is part of an ANR 'GENOPAT' project aiming to identify organic inhibitors of serine proteases involved in Netherton syndrome. Netherton's syndrome is a rare genetic skin disease caused by mutations in the gene encoding SPINK5 macromolecular inhibitor (LEKTI), it loses its regulating function of the activity of serine proteases (tissue kallikrein 5 , 7 and 14) esential for the skin homeostasis. There is currently no cure, topical application of exogenous inhibitors would therefore restore function of the epidermal barrier. Three strategies have been followed to identify new organic inhibitors of kallikreins, both rational approach and approaches based screening in silico and in vitro. 1) From a small laboratory collection of coumarin derivatives (240 molecules), suicide substrates of kallikreins were selected and characterized from a mechanistic point of view. 2) In parallel, a semi-rational approach based on the use of databases of experimental high throughput screening revealed 1,2,4-triazole compounds, forming acyl-enzyme with varying stabilities. 3) A virtual screening of the Chembridge commercial chemical library with about 600,000 organic molecules identified non-covalent kallikrein inhibitors, these inhibitors have a great structural diversity. Most inhibitors are among the most effective non-toxic with respect to healthy keratinocytes. Their effect on pro-allergic and inflammatory cytokines was analyzed in keratinocytes of patients with Netherton syndrome. A significant inhibition of the expression of these cytokines was observed

Full textDes etudes immunocytochimiques ont montre une co-localisation partielle des marquages obtenus avec notre immunserum anti-amidase et un anticorps anti-recepteur cb1 humain au niveau des neurones du ganglion supra-sophagien. Les clomocytes et les pores genitaux presentent egalement un marquage faible avec l'immunserum anti-amidase. La stimulation des ganglions nerveux par l'anandamide provoque l'augmentation de no et l'inhibition d'ampc suggerant l'existence de recepteurs de type cb1. Ce systeme endocannabinoide complet serait implique dans l'analgesie, la vasodilatation locale et la diminution de la reponse immunitaire de l'hote. La decouverte de ces nouveaux inhibiteurs de proteases a serine et d'un antithrombique, ainsi que la mise en evidence du systeme endocannabinoide chez les hirudinees, constituent une contribution importante dans la comprehension des relations hotes-parasites lors de la morsure

Full textInflammation has been demonstrated to play a central role in chronic obstructive pulmonary diseases (COPD). Neutrophil influx leads to a massive release of neutrophil serine proteases elastase (NSPs): elastase (HNE), proteinase 3 (Pr3) and cathepsin (CG) thereby leading to a protease/anti-protease imbalance. Besides the proteolytic damages to the lung extracellular matrix proteins, these proteases stimulate secretion of pro-inflammatory cytokines and therefore contribute to the perpetuation of inflammation. In order to target these proteases in COPD, we have examined the capacity of trappin-2 A62L (A62L T2), a genetically modified inhibitor which is able to inhibit all three serine neutrophil proteinases at the same time to protect the alveolar epithelium of the deleterious effects caused by the NSPS. In our study, we showed that T2 A62L significantly inhibits cell detachment and degradation of cell junction proteins (E-cadherin, ß-catenin and ZO-1, zonula occludens-1) of alveolar epithelial cells (A549) induced by each individual NSPS or by activated neutrophils. In addition to their antiproteolytic action T2 and T2 A62L reduced proinflammatory cytokines IL-6 and IL-8 release by A549 cells, previously stimulated by HNE or Escherichia coli lipopolysaccharide (LPS)
