Yu, Jinchao. "développement méthodologique et applications de la prédiction des interactions protéine-protéine." Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLS021.
Protein-protein interactions (PPIs) play essential roles in life. My PhD work aimed at developing advanced bioinformatics methods in the field of PPI prediction at the structural scale. My goal was to improve the predictive power of methods which model the structures of macromolecular assemblies (docking) and to tackle real-life problems faced by biologists.First, I developed HHalign-Kbest server using algorithms for the search of suboptimal solutions to gain better-quality models. Second, in the field of protein docking, I built InterEvDock server which can take co-evolutionary information into account. It yields better performance than other state-of-the-art servers. In order to further test our methods, we participated in CAPRI – an international challenge for prediction of protein interactions. Over years 2013-2016, our group ranked 1st at the 6th CAPRI evaluation meeting. At last, I developed a realistic benchmark dataset PPI4DOCK, largest dataset so far, in order to improve docking methods for the scientific community.In terms of applications, I was involved in a variety of collaborative projects with different labs. As representative examples, I searched for binding partners of the histone chaperone Asf1; I studied the CENP-F/Nup133 interaction in the context of mitosis and the Exo70/Abi interaction related to cell mobility regulation; I also simulated the binding modes of multiple peptides, partners of Ku complex involved in DNA repair pathway

Protein-protein interactions (PPIs) and supramolecular assemblies are essential for the functions of living cells. They play an important role in various biological functions, such as signal transduction, cell-cell communication, transcription, replication and membrane transport. Determining and characterizing such interfaces remains a challenge in structural biology. However, advances in the development of computational methods and the power of the computing resources available today have led to a considerable improvement in the accuracy of in silico predictions of three-dimensional models of protein assemblies.In this thesis, the aim was to predict the structure of a supramolecular assembly, called the Ubi metabolon, involved in the ubiquinone (UQ8) biosynthesis pathway in Escherichia coli. Ubiquinone is a prenol with oxido-reducing properties, localized in membranes, and highly conserved throughout evolution but also in different cells of organisms. It is composed of two main parts, an aromatic group with oxido-reducing properties, known as quinone or polar head, and a polyisoprenoid tail which is hydrophobic in nature. In this study, we are interested in the final stages of the biosynthetic pathway, in particular the modifications (methylations and hydroxylations) of the polar head. These reactions take place within the Ubi metabolon. The latter is made up of seven different proteins (UbiE, UbiG, UbiF, UbiH, UbiI, UbiJ, UbiK) catalysing six consecutive enzymatic reactions.In this work, we sought to predict the structure of the metabolon and were thus able to propose a protein subset that we called the 'core subunit'. This sub-unit includes all the partners and could be biologically functional. In parallel, a study was carried out on the UbiJ-UbiK2 heterotrimer, an essential molecular brick of the Ubi metabolon. A three-dimensional model of UbiJ-UbiK2 was proposed. Using a multi-scale modelling study, it was shown that it could be involved in the release of ubiquinone from membranes. Finally, the last part of this work focused on studying the behavior of a particular family of enzymes, the class A flavin mono-oxygenases, to which UbiF, UbiH and UbiI belong. A comparative study between a representative enzyme from this family, called PHBH, and UbiI was carried out, concluding that interactions with partners were necessary to stabilize these proteins within the Ubi metabolon.Taken together, this work and the proposed hypotheses provide a new insight into the supramolecular organization of the Ubi metabolon, both structurally and functionally. Our results open up new prospects for their experimental study
Mayer, Andreas. "Optimal immune systems : a ressource allocation and information processing view of immune defense." Thesis, Paris Sciences et Lettres (ComUE), 2017. http://www.theses.fr/2017PSLEE026/document.
Biological organisms have evolved diverse immune mechanisms to defend themselves against pathogens. Here we build mathematical models of immune systems optimally tuned to the statistics of pathogens. Beyond molecular details, different immune mechanisms differ in how protection is acquired, processed and passed on to subsequent generations -- differences that may be essential to long-term survival. To explain the observed diversity of strategies we compare the long-term adaptation of populations as a function of the pathogen dynamics that they experience and of the immune strategy that they adopt. We find that the two key determinants of an optimal immune strategy are the frequency and the characteristic timescale of the pathogens. Depending on these two parameters, we identify distinct modes of immunity, including adaptive, innate, bet-hedging and CRISPR-like immunities, which recapitulate the diversity of natural immune systems. Our results carry over to the general question of evolution in fluctuating environments, for which we provide novel analytical results in temporally correlated environments. The adaptive immune system provides protection through a broad repertoire of cells specific to different pathogens. To predict statistical features of well-adapted repertoires we analyze which repertoire minimizes cost of infection for a given distribution of pathogens. The theory predicts that the immune system has more receptors for rare antigens than expected from the frequency of encounters; and individuals exposed to the same infections have sparse repertoires that are largely different, but nevertheless exploit cross-reactivity to provide the same coverage of antigens. Our results follow from a tension between the statistics of pathogen detection, which favor a broader receptor distribution, and the effects of cross-reactivity, which tend to concentrate the optimal repertoire onto a few highly abundant clones. These predictions can be tested in high throughput surveys of receptor and pathogen diversity. We then explicitly consider how the adaptive immune system can learn the statistics of the environments from its past infection history in a Bayesian manner. We show that optimal repertoires can be reached by keeping memory of an infection through the selective proliferation of stimulated cells. The Bayesian perspective on repertoire dynamics provides an unifying conceptual framework to explain a number of features of immunological memory and suggests further experiments

This thesis focuses on the effects that information has on incentives. The three papers provide and explore some results when the information is the main variable of interest, it is made endogenous, not homogeneous between actors and evolving over time in a way that is not necessarily rational. The first paper studies hold-up problems in vertical hierarchies with adverse selection showing that as the bargaining power of the worker increases, distortions coming from asymmetric information vanish. Moreover, it studies the effect of schooling and degree of heterogeneity in the workforce on the allocation of bargaining power in regulating markets. The second paper relaxes the common assumption of homogeneous beliefs in principal-agent relationships with adverse selection. In an evolutionary learning set-up, which is imitative, principals can have different beliefs about the distribution of agents’ types in the population. Convergence to a uniform belief depends on the relative size of the bias in beliefs. In addition, the set-up is a version of a stable cobweb model. Our approach offers explanations for alternating periods of oscillating and relatively steady quantity. The third paper studies how the informative content of legal policies as strict-liability and fault-based, in case of moral concerns, influences the optimal design of liability regimes. Many recent cases show that an individual found to have caused harm faces not only the possibility of a legal sanction — e.g., the damages he must pay — but also social boycott, disapproval or stigma. The paper shows that the choice of a policy depends in a complex way on the magnitude of the harm and the “moral cost”.Keywords: Bargaining, Adverse Selection, Hold-up, Evolutionary Game Theory, Heterogeneous Beliefs, Bifurcation Theory, Boycott, Law Enforcement, Strict Liability, Negligence

Proteomics analysis corresponds to the qualitative and quantitative analysis of all proteins expressed in a cell or tissue under given conditions (proteome). Instrumental progresses in mass spectrometry and bioinformatics advances in recent years have allowed its establishment in life sciences. Diverse proteomics strategies thus allow identification and quantification of hundreds/thousands of proteins in complex samples, which classically allows physiopathological states to be characterized. However, proteomics is only emerging in the evolutionary biology field. This field aims at understanding the determinants of the diversity of organisms present on Earth and their “functioning”, including their adaptations to certain environmental constraints.The objective of this thesis was to study, from the organ to the eco-system, the proteomic variations induced by environmental changes, while adapting the different steps of the analysis to each type of sample, each organism, from sample preparation to data analysis. Through the introduction of an original quantitative de novo sequencing strategy, we studied the role of brown adipose tissue against obesity in a non-sequenced species: the vole. Other particular traits were explored, such as the reversible obesity of the grey mouse lemur or the interactions between sociality and longevity in the ant. The considered software solutions did not allow to robustly quantify peptides identified by de novo sequencing from fractionated samples, we thus determined that prefractionation allows for better proteome coverage. On the other hand, without prefractionation, de novo sequencing produces an undeniable gain. Finally, by studying the metaproteome of alpine soil biotic communities, we have highlighted the advantage of combining proteomics and genomics, in order to establish the most appropriate protein database and to “validate” proteomics data

Access to scientific information organised by university libraries and relied on Interlibrary-Loan has shaped a hidden economy. Interlibrary loan activities analysis is realised in the services marketing frame. Our analysis relies on both qualitative and quantitative approach and follows two main periods of time, 1975,1994 and 1995-2000. These two periods constitutes the first part of this work and conclude on desintermediation of university libraries by the numerical context. The second part look into traditional university library model to confront it to the numerical context. Growing integration in library collections reveals reintermediation process dynamics engaged in university libraries. Yet, the reintermediation process analysed by universities sections show that the shifting to a virtual library is not homogeneous. The conclusions emphasise that reintermediation depends also on dynamics or inertia of appropriation of electronic resources in every field. It is particularly illustrated by the differences observed between Science Technology and Medicine sections and Humanity and Social Sciences sections. Still unstable, virtual library model will finish his shaping with the confrontation of library services offer and users demand
