Full textToday several levels of complexity have emerged in the field of T helper cytokines: 1) the important number of distinct cytokines that Th cell can secrete in various combinations; 2) The multiplicity of signals that can act during Th differentiation to define the Th cytokine secretion profiles 3) The associations of these T helper secretion profiles with complex diseases. During my PhD I focused on these three levels of complexity and study the generation of T helper cytokine diversity and its association to breast cancer subtypes using multivariate analysis and statistical modeling. First, I was able to build the first statistical model linking 37 dendritic cell derived signals to 18 T helper cytokines. Using this model to derive in silico predictions, I was able to found a new role for IL-12p70 as a promoter of Th17 differentiation and as a main differential inducer of IL-17F independently of Il-17A in presence of IL-1. Then, studying the associations of the Th cytokine diversity with the different subtypes of human breast cancers, I found that Th17 cytokines were preferentially associated to Triple Negative Breast Cancer (TNBC). I found that TNBC patients with a high Th17 signature had a better survival. In addition, I showed that Th17 can be combined to clinical prognosis assessment scores, such as the Nottingham Prognosis Index, to better stratify TNBC patients in relevant subgroups for survival prognosis assessment

Full textHuman immunity is essentially driven by dendritic cells and T helper cells. When dendritic cells detect a pathogen, they will instruct T helper cells to adopt the adapted phenotype for the specific threat encountered. T helper cells are subdivided in multiple subsets, characterized by particular sets of cytokines. Each T helper subset has specific functions and is involved in the clearance of distinct pathogens. If T helper responses are not precisely regulated, they can become pathogenic, in this case T helper pathways can be considered as potential targets for therapy. In this context, I focused my PhD work on studying T helper cell subset diversity and regulation. First, I demonstrated the ability of TSLP-activated dendritic cell to induce T follicular helper cell polarization. Then I participated in building a mathematical model capable of predicting T helper cell response to dendritic-cell derived signals. This model allowed us to identify the specific role of IL-12p70, in an IL-1 context, to induce IL-17F without IL-17A. Finally, I monitered eight T helper and T follicular helper cell populations in peripheral blood from atopic dermatitis patients treated with Dupilumab, an immunotherapy targeting the IL-4 receptor alpha subunit, and was able to show a correlation between decrease of Th17 cell percentage and improvement of EASI clinical score. Overall, my work on Th phenotype diversity provides key mechanistic insight with potential application in immunotherapy
Diaz, Herrero Alba. "Characterization of Tumor Immune Microenvironment in Human Diffuse Large B-cell Lymphoma." Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASL057.
Full textDiffuse Large B-cell Lymphoma (DLBCL) is the most prevalent subtype of non-Hodgkin's Lymphoma worldwide, characterized by an abnormal proliferation of mature B cells. It is an aggressive B-cell malignancy for which the current therapeutic strategies are still insufficient. The tumor microenvironment (TME) is the dynamic network of cells and all elements surrounding and interacting with the tumor. It plays an important role in cancer development, treatment response, and patient survival. Consequently, investigating the TME in DLBCL patients is crucial to discover the mechanisms leading to relapse and identify prognostic biomarkers. However, its diffuse tissue structure presents a challenge in elucidating the cellular organization and communication within the TME. The objective of my Ph.D. thesis is to conduct a comprehensive multimodal characterization of the immune cells within the DLBCL tumor microenvironment.To facilitate access to human samples, I developed and implemented an ethically approved clinical research protocol and a circuit of tissue and blood samples from patients with DLBCL treated at Saint Louis hospital, ensuring that the patient cohort reflects the heterogeneity of the disease.First, I performed a deep characterization of T lymphocytes, with special focus on describing their role within the DLBCL tissue. Indeed, Tumor-infiltrating T-cells (TILS) are key players in the NHL TME, presenting different subtypes and cell states. I apply multiparametric flow cytometry and high-dimensional spectral cytometry to investigate the complex landscape of T diversity in DLBCL biopsies, as well as their communication patterns with other immune cells in the tissue. The unsupervised analysis approach identified unexpected T-cell subtypes at a protein level, compared to tissue control and other lymphoproliferative disorders. Furthermore, the ligand-receptor expression analysis enabled the cell-cell communication study of those T-cell subpopulations within the TME context. Second, I aimed to characterize transcriptomic immune landscapes at a large scale within DLBCL tissue. However, RNA sequencing technologies characterize isolated cells from dissociated tissues with a loss of spatial context. I applied spatial transcriptomics, a cutting-edge technology that enables gene expression mapping in formalin-fixed paraffin-embedded samples of DLBCL biopsies, thus preserving their morphological information. I identified distinct anatomically restricted gene expression profiles in DLBCL samples, defying the historical notion of DLBCL diffuse architecture. These profiles can be classified into ecosystems that differ in cellular composition, functional patterns, and neighborhood characteristics. Moreover, their spatially resolved signatures classify patients with different overall survival revealing the prognostic potential of these spatial identities.Third, I evaluated the effects of altering the communication between NK cells and malignant B cells in DLBCL. I performed a functional in vitro assessment of a blocking antibody developed by the pharmaceutical company Servier. The functional assays demonstrated the effect of the molecular candidate in co-culture settings by improving cytotoxic functions of NK cells against tumor cells. These findings highlight the importance of targeting the interaction between effector cells and malignant B cells to develop effective therapies for DLBCL.This multidisciplinary project carried out on human samples provides a deep understanding of the heterogeneity of immune cells in DLBCL microenvironment at a protein and transcriptomic level while considering their spatial organization. Hence, this project holds significant therapeutic potential, by gaining insights into the disease heterogeneity and its impact on clinical outcome. This project could eventually lead to the discovery of new potential biomarkers and effective therapeutic strategies for DLBCL patients

Full textAdaptive immunity is mainly orchestrated by CD4 T helper cells. They have the ability to polarize in several subsets, each associated to a suitable phenotype for the encounter pathogen. T helper cell activation can be regulated by co-stimulator, such as OX40 Ligand, or co-inhibitor immune checkpoint molecules. These molecules have been studied individually, in specific conditions. However, context-dependency may explain large parts of the functional variability of biological molecules on a given output. Currently, there is no framework to analyze and quantify context-dependency of a molecule over multiple contexts and response outputs. My PhD project focused on OX40L function on T helper cell polarization, in 4 molecular and 11 cellular contexts. We measured 17 T helper cytokines and developed a statistical modeling strategy to quantify OX40L context-dependency on these cytokines. This revealed highly variable qualitative and quantitative context-dependency scores, depending on the output cytokine and context type. Among molecular contexts, Th2 was the most influential on OX40L function. Among cellular contexts, dendritic cell type rather than activating stimulus was dominant in controlling OX40L contextdependency. My thesis work unveils the complex determinants of OX40L function, provides a unique framework to quantify the context-dependent functional variability of any biomolecule, and supports that context-dependency should be more taken into consideration in future studies
