4 Abstract Mast cells are involved in variety of immunological processes, but they are mostly known for their role in allergy and asthma. As asthma and allergy are serious diseases with spreading tendency during last decades, mast cells are subject of intensive research. It is expected that studies of mast cell signalling pathways will contribute to our understanding of the nature of these diseases and help to design efficient treatment strategies. In an attempt to identify genes responsible for asthma disease, genome-wide screening methods have been currently applied. Using these methods, mutations in ORMDL3 (Orosomucoid1-like) protein were found out as a high risk asthma factor. ORMDL3 is a member of evolutionary conserved ORMDL family, comprising in mammals also of ORMDL1 and ORMDL2. Physiological function of these proteins is poorly understood and it has not been studied in mast cells. We decided to study the role of ORMDL proteins in mast cells. Lentiviral delivery system was optimised for generation of stable knock-downs (KD) of all three members of the ORMDL family in primary mast cells. The ORMDL gene expression was measured by improved qPCR (quantitative PCR) reaction buffers. We found that all ORMDL genes are expressed in mast cells in order ORMDL3 > ORMDL2 > ORMDL1. Next, we investigated the...
