Mast cells are the main effector cells of allergic processes. These cells play a central role in immediate phase of allergic reaction and are involved in chronic allergic inflammation. What is more, mast cell-derived mediators take part in airway remodeling in the course of chronic bronchial asthma. Therefore, it seems to be very important to explain the mechanisms influencing IgE-dependent mast cell activity. This paper describes the down-regulating IgE-mediated mast cell stimulation mechanisms associated with immunoreceptor tyrosine-based inhibition motifs (ITIM), such as FcγRIIB, glycoproteins CD300a and gp49B1, paired immunoglobulin-like receptor B (PIR-B), platelet endothelial cell adhesion molecule-1 (PECAM-1) and CD172a.
