Before reacting against non-self infectious agents, the immune system is educated to tolerate the host molecular structure (self). The induction of self-tolerance is a multistep process that begins in the thymus during fetal ontogeny (central tolerance) and also involves inactivating mechanisms outside the thymus (peripheral tolerance). The thymus is the primary lymphoid organ implicated in the development of competent and self-tolerant T cells. During ontogeny, T cell progenitors originating from hemopoietic tissues (yolk sac, fetal liver, and then bone marrow) enter the thymus and undergo a program of proliferation, T cell receptor (TCR) gene rearrangement, maturation and selection. Close interactions between thymocytes (pre-T cells) and the thymic cellular environment are crucial both for T cell development and induction of central self-tolerance. Thymic epithelial and stromal cells synthesize polypeptides belonging to various neuroendocrine families. The thymic repertoire of neuroendocrine-related precursors transposes at the molecular level the dual role of the thymus in T cell negative and positive selection. Thymic precursors not only constitute a source of growth peptides for cryptocrine signaling between thymic stromal cells and pre-T cells, but are also processed in a way that leads to the presentation of self-antigens by thymic major histocompatibility complex (MHC) proteins. Thymic neuroendocrine self-antigens often correspond to peptide sequences highly conserved during the evolution of their corresponding family. The thymic presentation of some neuroendocrine self-antigens is not restricted by MHC alleles. Following the presentation of neuroendocrine self-antigens by thymic MHC proteins, the T cell system might be educated to tolerate main hormone families. Recent experiments argue that a defect in the thymic essential tolerogenic function is implicated as an important factor in the pathophysiology of many autoimmune diseases. [less ▲]

This work describes a centralized control for Multi-Terminal Direct Current (MTDC) grids. It is based on Model Predictive Control (MPC) whose aim is to satisfy a desired schedule, while avoiding or correcting any system limit violation. The central controller collects voltage and power measurements from the converters of the system in regular intervals and sends back converter power setpoints. The latter are calculated by solving a quadratic programming problem subject to linear constraints and using a simplified model for the DC system. In addition, the overall MTDC grid control structure including the local and the centralized controllers is described. [less ▲]

Alzheimer's disease represents an important problem for our societies, both in social and economical dimensions. Built in July 1997, the day care center of Liege aims at practicing strategic cognitive interventions in early Alzheimer patients or when pathological memory impairments occur. By means of an interdisciplinary work (by neuropsychologists and occupational therapists), the ultimate goal of the interventions is to facilitate the patient's autonomy in activities of daily living. Because of the variability of clinical symptoms of the disease, the goal of these cognitive interventions is to optimize the performance of each patient by making the most of its preserved abilities. Moreover, another goal of the day care center is also to support the caregivers, by giving them advices in order to adequately face with difficulties presented by the patient. [less ▲]
