1. Progesterone metabolites : learning, tolerance, antagonism & metabolism
Abstract : Progesterone metabolites as allopregnanolone, isoallopregnanolone and tetrahydrodeoxy-corticosterone (THDOC) are increased in the luteal phase of the menstrual cycle, throughout pregnancy and during stress. Allopregnanolone and THDOC are neurosteroids with 3α-hydroxy, 5α-configurations and positive modulating effect on the GABAA receptor. READ MORE

2. Ecology and evolution of tolerance in two cruciferous species
Abstract : Tolerance to herbivory is the ability of plants to maintain fitness in spite of damage. The goal of this thesis is to investigate the genetic variation and expression of tolerance within species, determine whether and in what conditions tolerance has negative side-effects, and how tolerance is affected by different ecological factors.

3. T cell Tolerance - Cellular and molecular features of immune regulation
Abstract : The immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. READ MORE

5. On the regulation of immune responses to dietary and self antigens
Abstract : Regulatory mechanisms are necessary to avoid the misdirected aggressive immune responses responsible for the pathology seen in autoimmunity and allergy. Thymic-derived CD4+CD25+ regulatory T cells are indispensible for this regulation. We investigated if CD4+CD25+ Treg prevents auto-reactive responses in adult peripheral blood and cord blood.
