16. Neuroimmune Interactions of Enteric Neurons and Mast Cells: Friends or Foes?
Sammanfattning : Psychological distress or physical strain lead to reduced blood flow in the intestine since other organs are prioritised. One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). LÄS MER
17. Regulation of human mast cell development
Sammanfattning : Mast cells are multifunctional effector cells of the immune system and are best known for theirparticipation in allergic reactions. The aim of this thesis was to investigate how the stem cell factor(SCF)-dependent development of mast cells from cord blood can be regulated by different factors, and tostudy how immature mast cells circulating in the blood can be recruited into the tissue.

18. The Role of Fc gamma Receptors and Mast Cell Chymase in Autoimmune Arthritis
Sammanfattning : In autoimmune diseases such as rheumatoid arthritis (RA), self-reactive antibodies are present at high levels, which contributes to disease pathogenesis. The antibodies mediate their effect predominantly by binding to Fc gamma receptors (FcγR) on various leukocytes, such as monocytes, macrophages and mast cells, where FcγR ligation leads to cell activation.

19. Signal Transduction in Mast Cell Migration
Sammanfattning : Mast cells are essential effector cells in the immune system as they release several inflammatory mediators. An accumulation of mast cells has been described in inflammatory conditions such as asthma and allergic rhinitis. LÄS MER
20. New Aspects of Mast Cell Progenitors in Health and Disease
Sammanfattning : Mast cells are tissue-resident immune cells that are well known for their involvement in asthma and allergy. They originate in the fetal yolk sac, or in the bone marrow. From the bone marrow, they are released as immature progenitors that are transported via the blood circulation to the peripheral tissue, where they mature. LÄS MER
