1. On the regulation of immune responses to dietary and self antigens
Sammanfattning : 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. LÄS MER
2. Expression of Tissue Antigens in Human Pluripotent Stem Cells and Alterations During Differentiation : Potential application in regenerative medicine for treatment of terminal cell and organ failure
Sammanfattning : The major limiting factor in the treatment of patients with end-stage organ failure is the insufficient number of human organs available for transplantation. An unlimited access to human cells, tissues and organs would also open up possibilities to treat several chronic diseases, such as diabetes, neurological and cardiovascular diseases, affecting millions of patients worldwide.

3. Affinity biosensors based on a capacitive transducer
Sammanfattning : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. LÄS MER
4. Characteristics and functions of thymic exosomes in human and mouse
Sammanfattning : Thymocytes develop in the thymus to become a functional pool of T-cells in the periphery. To achieve this, the thymocytes go through several steps of maturation and selection within the thymus. LÄS MER
5. The regulation of B cell responses in systemic autoimmunity
Sammanfattning : Our immune system is a complex network made up of physical barriers and specialized proteins, cells and organs that all work together to prevent pathogens from causing disease in the body. Once the immune system has successfully mounted an immune response upon intrusion of a pathogen it will mount an immediate and stronger response against any subsequent exposure to it. LÄS MER
