1. The ups and downs of T cells The role of costimulatory molecules in the modulation of T cell responses
Sammanfattning : T cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. LÄS MER
2. Studies on the function of CD4CD25 regulatory T cells: An in vitro approach
Sammanfattning : Immunological self-tolerance is a state of the whole organism where deleterious responses are either avoided or regulated. Breaking of immunological tolerance will lead to autoimmune disease or chronic inflammatory conditions. LÄS MER
3. T cells and costimulatory factors in myasthenia gravis
Sammanfattning : The autoimmune disease myasthenia gravis (MG) is characterized by muscle weakness due to a loss of acetylcholine receptors (AChR) at the neuromuscular end plate. Most MG patients have pathogenic antibodies directed against the receptor. We provide further evidence that T cells are important for establishment and continuation of the disease. LÄS MER
4. Modulation of Autoimmunity by Linomide treatment or interference with costimulation
Sammanfattning : Linomide is a potent immunomodulator that has been shown to inhibit autoimmunity in several animal models of autoimmune disease. We have approached the cellular and molecular mechanism of Linomide by investigating its effect on thymocyte development and its capacity to modulate the expression of activation markers on antigen presenting cells (APCs).

5. Inhibition of T cell responses to autoantigens and allergens by CD25+ regulatory T cells from thymus, cord and adult blood
Sammanfattning : Autoimmune diseases and allergies are a growing problem in the western world today. Tolerance is primarily established by clonal deletion in the thymus. Despite this auto-reactive T cells are normally present in most individuals, which suggests that mechanisms of peripheral tolerance operate to silence potentially pathogenic T cells. LÄS MER
