ClinConnect Summary

Systemic mastocytosis is a disease characterized by an abnormal accumulation of mast cells in skin, bone marrow and viscera. Precise mechanisms of events leading to the migration and proliferation of mast cells in skin is not known. We propose to investigate the in vivo cytokine and chemokine production patterns of human skin in patients with mastocytosis and compare these findings to those of patients with atopic dermatitis and to healthy volunteers, using the suction blister technique. The cytokines/chemokines of interest in this study are stem cell factor (SCF), interleukin (IL)-3, IL-4,...
