A pediatric patient performing IOS. The patient is using a nose-clip and making a tight seal with his lips at the mouthpiece of the IOS device. The results of IOS testing are displayed on the computer monitor. Read more about it.
The mast cell is the focus of the Mast Cell Biology Section (MCBS) research effort. This multifunctional inflammatory cell is involved in both innate and acquired immunity and plays a central role in the induction of allergic inflammation. An integrated program investigating mast cell biology includes studies into the growth and differentiation of mast cells, mast-cell signal transduction, and the products generated by mast cells that lead to disease. The MCBS program emphasizes basic research that may be translated into the clinic, where protocols include studies on the pathogenesis of urticaria, anaphylaxis, and mastocytosis. Research efforts have contributed to the identification of mutations in clonal mast cell disorders, understanding signaling through KIT and the high affinity IgE receptors, and how alterations in the control of mast cell mediator production affect human disease.
