The composition of T lymphocyte's compartments is constantly modified, because of the production of new TCR specificities, selection after antigen encounter and cell death. In order to control the cell transition between central and peripheral compartments, mechanisms of homeostatic regulation maintain the immune system in a steady-state. As seen in any ecosystem, T lymphocytes are in competition for limited selection niches and resources. During this thesis, we have used mice in order to analyse the behaviour of CD8+ T ab lymphocytes after an environmental perturbation. We have also used MHC class I molecules as a model of resource necessary for CD8+ T cell survival.We have first studied central and peripheral selection of CD8+ T cells dou...
