HMGN2: a novel antimicrobial effector molecule of human mononuclear leukocytes?

abstract：:Previous studies about basophils and mast cells identified the ability of IgE to up-regulate FcepsilonRI expression by a process that depends on stabilization of the surface receptor by IgE. However, the mechanism of loss from the cell surface, when unoccupied, is not known. The current studies have examined whether u...
