Abstract (sommario):

Recent years have witnessed a rapid proliferation of gene editing in mammalian cells due to the increasing ease and reduced cost of targeted gene knockout. There has been much excitement about the prospect of engineering T-cells by gene editing in order to provide these cells with optimal attributes prior to adoptive cell therapy for cancer and autoimmune disease. I began by attempting to compare short hairpin RNA (shRNA) and zinc finger nuclease (ZFN) approaches using the CD8A gene as a target for proof of concept of gene editing in Molt3 cells. During the course of my studies the clustered r

Abstract (sommario):

Die Herstellung von T-Zellen mit definierten Spezifitäten durch den Transfer von T-Zellrezeptor (TCR) Genen ist eine effiziente Methode, um Zellen für eine Immuntherapie bereitzustellen. Eine besondere Herausforderung ist dabei, ein ausreichend hohes Expressionsniveau des therapeutischen TCR zu erreichen. Da T-Zellen mit einem zusätzlichen TCR ausgestattet werden, entsteht eine Konkurrenzsituation zwischen dem therapeutischen und dem endogenen TCR. Bevor diese Arbeit begonnen wurde war nicht bekannt, welche TCR nach einem Gen-Transfer exprimiert werden. Daher haben wir Modelle etabliert, in de

Although studies using B cell deficient mice have been useful in understanding the importance of B cells under different conditions, it is difficult to then dissect exactly how B cells could be regulating T cell responses. By transferring OT-II transgenic T cells into either B cell deficient (μMT) or C57BL/6 mice, expansion and contraction of T cells can be tracked <i>ex vivo. </i>Expansion of OT-II cells is reduced in μMT mice compared to C57BL/6 mice. Thus, B cells can provide costimulatory signals, secrete cytokines and influence the lymphoid microarchitecture. To dissect which B cell facto

Abstract (sommario):

Previous research has provided evidence that CD8 T cells mediate immunity against infection with Theileria parva. However, the immunity induced by one parasite strain doesn‟t give complete protection against other strains and this is associated with parasite strain specificity of the CD8 T cell responses. There is evidence that such strain specificity is a consequence of the CD8 T cell responses of individual animals being focused on a limited number of immunodominant polymorphic peptide-MHC determinants. Dominant responses to the Tp2 antigen have been demonstrated in animals homozygous for th

Abstract (sommario):

Graft-versus-host disease (GvHD) remains the main complication associated with haematopoietic stem cell transplantation (HSCT). GvHD is caused by allo-reactive donor T cells mounting an attack against specific target tissues. CD4+CD25HiFoxp3+ regulatory T cells have been shown to modulate GvHD in vitro and also in vivo animal models. More recently early stage clinical trials have described the successful use of Treg to reduce the incidence of GvHD following HSCT. The aim of this study was to investigate further the suppressive mechanisms by which Treg are able to modulate GvHD and assess the i

Abstract (sommario):

T cell responses are subject to several layers of regulation in order to prevent a detrimental effect on the host. Bystander T cell activation occurs via TCR-independent mechanisms, and as such evades certain control checkpoints. The apparent irrationality of this concept, coupled with the finding that the overwhelming majority ofT cells activated during viral infection are antigen-specific, has lead to a debate over the existence of the phenomenon. In this study, I sought to build upon previous work with murine models, to demonstrate the existence of bystander T cell activation in primary hum

Abstract (sommario):

Allogeneic hematopoietic stem cell transplantation is considered to be the main means of treatment for hematological malignancies. However, disease relapse and graft versus host disease remain the major cause of death post transplantation. To reduce the risk of graft versus host disease and in order to improve the graft versus leukemia effect, genetically engineered T-cells are used to express tumor specific antigens. This is either through the transfer of a recombinant antigen-specific T cell receptor (TCR) or through the introduction of antibody-like recognition in chimeric antigen receptors

Abstract (sommario):

Regulatory T cells (Tregs) have shown considerable potential in the treatment of murine models of immuno-pathology. Whilst poly-clonal Tregs are able to suppress immuno-pathology in a number of models, the superiority of Ag-specific Treg treatment has been demonstrated using Tregs from T cell receptor (TCR)- transgenic animals. Translation of these promising results to the clinic has been hampered by difficulties in isolating or enriching the rare Ag-specific Tregs from the polyclonal population. Here I describe two distinct approaches to generate Ag-specific T cells with regulatory ability: f

Abstract (sommario):

Immunological tolerance, that is, the failure to mount an immune response to an otherwise immunogenic molecule, is one of the fundamental questions in immunology. The fact that lymphocytes express antigen receptors that are generated randomly and have the potential to recognize any conceivable antigen, adds another puzzle to the physiology of immunological tolerance. The other side of the coin, the general absence of immune responses to self antigens, is ensured by a tight regulation and several selection steps during T and B cell differentiation. One of these processes is the different

Abstract (sommario):

T lymphocytes are essential components of the immune system and as such are continually regulated by a variety of factors. Every step of their development, survival and function is tightly monitored to ensure their ability to recognize most foreign agents and mount adaptive immune responses during pathogenic infections, while remaining tolerant to self-antigens. Among the many factors that participate in the regulation of T cell development and function are the cytokines. Cytokines that signal through the common gamma (γс) chain and the Janus kinase 3 (Jak3) include IL-2, -4, -7, -9, -15, and

Interleukin-7 is an essential cytokine that plays a major role in the development and homeostatic maintenance of T-cells.

Recognition of a cognate peptide-MHC molecule by its T cell receptor (TCR) triggers a critical cascade of protein re-organisation and clustering at the cell interface.

The glycoprotein CD2 with its ligand CD48 (mouse) or CD58 (human) has been shown to act as an important adhesion/co-stimulatory molecule influencing the T cell activation. While initial analysis of the knockout mouse revealed redundancy with LFA-1 and CD28, activity of this pathway has been correlated with enhanced

Humoral immunity provides protection against subsequent infections. Antigen-specific, high-affinity, class-switched antibodies are produced by B cells through rounds of proliferation, B cell receptor rearrangement and selection in the germinal centres (GC).

The aim of my thesis is to investigate whether there is more than one type of T cells within the TFH population and whether it has important functional consequences. First
