Tang, Chongfa. "The inflammatory response of primary epithelial cells of the female genital tract to Chlamydia trachomatis infection, and its exacerbation by type-I interferon." Electronic Thesis or Diss., Sorbonne université, 2022. https://accesdistant.sorbonne-universite.fr/login?url=https://theses-intra.sorbonne-universite.fr/2022SORUS121.pdf.
Full textChlamydia trachomatis is an obligate intracellular bacterium, which grows mainly in epithelial cells of the mucous membranes of the genital tract. Asymptomatic in most cases, infections with this pathogen can lead to pelvic inflammations. The inflammation itself can lead to fibrosis and tubal infertility in women. To better understand the pathological manifestations in the female genital tract (FGT), it is important to study the response of epithelial cells, which constitute the first line of host defense against C. trachomatis infection. To this end, we developed a simplified protocol to isolate a very pure fraction of primary epithelial cells from the FGT of patients undergoing hysterectomy. We observed that these primary epithelial cells were less permissive to C. trachomatis infection than the cell line classically used in laboratories, i.e. HeLa cells. We have shown that the difference in culture medium and the addition of serum in HeLa cell cultures explain a large part of these differences. However, when tested in an identical culture medium, primary ectocervical epithelial cells were found to be less permissive than HeLa cells towards C. trachomatis infection. Finally, primary epithelial cells expressed overall more pro-inflammatory cytokines, both basally and after C. trachomatis infection, than HeLa cells, suggesting a strong capacity of primary epithelial cells to mount an inflammatory response. We then focused on understanding why type I interferon (IFN-I) acts synergistically with C. trachomatis infection towards the pro-inflammatory response of epithelial cells. We demonstrated that IFN-I, but not C. trachomatis, increased the expression of several bacterial pattern recognition receptors (PRRs). Expression silencing of TLR3 receptor, or deletion of this gene, prevented synergetic effect between IFN-I and C. trachomatis. We also identified the intermediate signaling pathway between IFN-I receptor activation and TLR3 expression, as well as the signaling downstream of TLR3 activation, which results in the expression of the pro-inflammatory cytokines interleukin-6 and 8. Based on these data, we conclude that IFN-I exacerbates the host inflammatory response triggered by C. trachomatis infection via increased TLR3 expression, and that this synergetic effect between IFN-I and bacteria on pro-inflammatory signaling in epithelial cells may play a role in the tissue damage that results from infection in some of the patients

Full textThe understanding of the function of ryanodine receptor subtype RYR3 needs the study of RYR3 alternative splicing. In mouse smooth muscles, we have shown the expression of short dominant negative variant. In fact, in duodenum, the short isoform inhibits the RYR2 subtype responsible for the release of stored calcium in reticulum. The complete isoform of RYR3 cannot interact with the short isoform but encodes spontaneous calcium oscillations only when the reticulum is calcium overloaded. This alternative splicing is also modulated in myometrium during pregnancy. Near the term, the expression of complete RYR3 isoform is dominant whch allows cyclic ADP-ribose-dependent transduction pathways to release stored calcium that participates to uterine contraction

Full textChlamydia infections represent a major public health issue as over 600 million people world-wide are infected with these intracellular bacteria. We examined the role of the Toll-like receptors (TLR) TLR2, TLR4 and the cytosolic receptor NOD1 in the inflammatory response during Chlamydia infection. We observed that neither TLR4 nor NOD1 play a crucial role during the inflammatory response to Chlamydia. However TLR2 is an important mediator in the innate immune response to Chlamydia infection and appears to play a major role in both early production of pro-inflammatory mediators and development of chronic inflammatory pathology. The major importance of TLR signaling pathways during Chlamydia infection was shown in mice deficient for MyD88 (an adapter molecule involved in all TLR signaling pathways except for TLR3). These mice were severely impaired in their ability to up-regulate pro-inflammatory cytokines and chemokines, and to clear the pathogen from their genital tracts. Finally, we showed that the purinergic receptor P2X7, a receptor for « danger signals » released from infected cells or sites of inflammation, participates in control of Chlamydia infections by both direct microbicidal activity and the secretion of the pro-inflammatory cytokine IL-1ß. In conclusion, we showed that the TLRs and the P2X7 receptor contribute to the development of the inflammatory response after a Chlamydia infection

Full textBreast cancer is the most common lethal cancer in women in worldwide. In spite of screening improvement in early stages of tumor development, it remains difficult to cure late stages when metastases are begun. Metastatic development depends on migratory capacities acquisition by epithelial cells, involving a cytoskeleton remodeling, highly depending of intracellular calcium concentration. While plasma membrane calcium channels have been highly studied in migration processes, the role of IP₃Rs remains misunderstood. Firstly, we highlighted a correlation between IP₃R3 expression level and migratory potential of three human breast cancer cell lines with different migratory potential. Indeed, the more the migratory profile increases, the more is the expression of IP₃R3. Moreover, IP₃R3 expression modulation regulates their migratory capacities. The migratory capacities decreased when silencing IP₃R3, whereas they increased by overexpressing IP₃R3 in the low migratory breast cancer cell line (MCF-7). Furthermore, IP₃R3 silencing reveals an oscillating calcium profile, while its overexpression induces a sustained calcium profile. Secondly, we demonstrated a reverse correlation between IP₃R3 expression level and rounded shape of these three cell lines. Indeed, the longer the cell has an elongated morphology, the greater the IP₃R3 expression is important. Moreover, IP₃R3 silencing induced a rounded shape of migrating cells and decreased of protrusions and adhesion. Our results suggest IP₃R3 implication in modulation of cytoskeleton actors. Indeed, knockdown of IP₃R3 induced a decrease of ARHGAP18 and Cdc42 expression, RhoA and FAK_⁸⁶¹ activity, and a reorganization of profilactin cytoskeleton. Furthermore, in a migratory model, oscillating profile is revealed at wound realization and predominates 3 h amer in cells of the front wound whereas it sets up in cells of back only amer 3 h. The spatio-temporal gap of this oscillating calcium signal reflects an intracellular calcium dynamic essential to migratory processes and cytoskeleton remodelling in breast cancer. In conclusion, our results reveal a key role of IP₃R3 in migratory processes by profilactin cytoskeleton remodeling through ARHGAP18/ RhoA/ FAK pathway thanks to intracellular calcium profile modulation

Full textTLR3 is an endosomal Toll-like receptor (TLR) that mediates immune responses against viral infections upon activation by its ligand double stranded RNA, a replication intermediate of most viruses. TLR3 is expressed widely in the body and activates both the innate and adaptive immune Systems. However, little is known about how TLR3 intracellular trafficking and maturation are regulated. Here we show that newly synthesized endogenous TLR3 is transported through the ER and Colgi apparatus to endosomes, where it is rapidly cleaved. TLR3 protein expression is up-regulated by its own ligand leading to the accumulation of its cleaved form. Furthermore, TLR3 signaling and cleavage are sensitive to a cathepsin inhibitor. Screening of the human cathepsin family by RNA interference identified cathepsins B and H as key mediators of TLR3 processing. Cleavage occurs between aa 252 and 346, and results in a functional receptor that signals upon activation. A truncated form of TLR3 lacking the N-terminal 345 amino acids does also signal from acidic compartments in response to ligand activation. Taken together our data indicate that TLR3 proteolytic processing is essential for its function and suggests a mechanism of tight control of TLR3 signaling and thus inflammation

Full textThe multiple myeloma (MM) is an incurable haematological disease. MM is characterized by the proliferation of clonal plasma cells in the bone marrow. Among genetic alterations found in myeloma plasma cells, the t(4;14) translocation is found in 15% of MM. The t(4;14) induces the deregulation of two oncogenes, FGFR3 and MMSET, and is associated with a poor prognostic. During my PhD, I studied the physiopathology of the MM with the t(4;14) translocation, the oncogenic function of the FGFR3, the molecular mechanisms involved in the poor prognostic and the chemoresistance. Moreover, I studied the development of two targeted therapies. My results show the anti-tumoral effect of the masitinib (a specific inhibitor of the tyrosine-kinase activity of FGFR3) in vitro and in vivo. We found that this inhibitor modulates the expression and the activity of the Src kinase lyn, which is expressed on the plasma cells with or without the t(4;14) translocation. Today, the use of proteasom inhibitors is limited by the occurrence of severe side-effects and résistance. Our results show the anti-tumoral effect of the HIV protease inhibitor called nelfinavir, in vitro and in vivo. Nelfinavir induces the activation of the pro-apoptotic pathway of the UPR System, the akt dephosphorylation, and impairs bortezomib resistance in MM cell Unes. This work shows, for the first time, the importance of these two targeted therapies and allows to identify new targets. Several clinical trials of the two drugs have already started

Full textIn the first part of this thesis, the influence of the C-3 carbonyl group conformation of 3-carboxy- β-carbolines on their benzodiazepine receptor affinities was studied. For this purpose rigid -carboline analogues in which the carbonyl group was restrained in an s-cis position were synthesized. Evaluation of the in vitro binding affinities of these derivatives permitted confirmation of our working hypothesis that the s-cis conformation of active 3-carboxy β-carboline is preferentially recognized by the benzodiazepine receptor. In the second part, a contribution to a study of the structure-activity relationships of a new family of benzodiazepine receptor ligands was made. Finally, in the third pan of the thesis, attempts to synthesize a new family of diazepine- β-carboline hybrids are described. The various strategies used for this purpose, of which one was successful, also led to the synthesis of novel tetracyclic β-carbolines displaying very high receptor affinities in vitro

Full textType 2 diabetes is a metabolic pathology characterized by chronic hyperglycemia. The disease progressively induces organ damage through several mechanisms, one of the which is the glycation pathway. This chemical reaction results in a bond forming between a reducing sugar and the amine function of an amino acid, a peptide or a protein. Over the last 30 years several studies have described therapeutic strategies to reduce the formation and accumulation of glycation products. Scientists have investigated synthetic or natural molecules that can metabolize or sequester precursors of glycation products. Others have tried to inhibit the main receptor of advanced glycation endproducts (RAGE) with specific antibodies or receptors. Despite these efforts, there is still no effective “anti-glycation” treatment able to reduce glycation products in the organism or limit their deleterious effects on health.Scientists have recently investigated the gut microbiota, and notably the actions of probiotics on glycemic parameters and the complications associated with diabetes. Preclinical and clinical trials have shown the effect of certain probiotics on weight gain and upon glucose metabolism. But while these studies have reported the effect of probiotics on different glucidic parameters, no one has yet investigated their effect on glycation.Thus, the double goal of this thesis was to compare different rodent models of glycation in a type 2 diabetes context (genetic and dietary-induced obesity (DIO) models), and then to use the most pertinent model to study the effects of a specific bacterial strain, Lactobacillus fermentum ME-3, on glycation and metabolic disorders in this diabetic context. The ensemble of glycation products measured, namely furosine, free and protein-bound carboxymethyllysine (CML) in organs and in plasma, were performed by liquid chromatography coupled with tandem mass spectrometry.Firstly, we showed that the genetic LepRdb/db model of diabetes exhibited significantly greater glycation in tested organs and fluids (kidneys, lungs, heart, liver and plasma) compared with DIO models (High Fat and High Fat High Sucrose Diet) which, despite dietary-induced weight gain and glucose intolerance, showed no significant increase in furosine or CML levels.Secondly, using the genetic model of diabetes, we showed that a treatment with ME-3 over three months in wild-type mice (LepRdb/+) and LepRdb/db had beneficial effects upon weight gain (-4.6% and -14% in db/+ and db/db mice, respectively) and glucose tolerance. We also observed a reduction of furosine levels in kidneys (-14.5% and -12.3% in db/+ and db/db mice respectively) and a reduction of free CML in both the kidneys (-18% and -25% in db/+ and db/db mice, respectively) and the lungs (-10% and -19% in db/+ and db/db mice, respectively). This preclinical study observed other effects of the ME-3 strain on health. Among these, the most marked was a reduction in development of hepatic steatosis (-23% and -41% of hepatic triglycerides, -12% and -21% of ALAT (a marker of liver injury) in db/+ and db/db mice, respectively; and a 27% reduction in db/db mice of TNF-α, an inflammation marker).To conclude, this work has characterized a rodent model of type 2 diabetes for the study of glycation and future development of therapeutic strategies against glycation. It has also highlighted the beneficial effects of the ME-3 strain on both glycation and metabolic disorders in a type 2 diabetes model
