Overproduction of IgE induces macrophage-derived chemokine (CCL22) secretion from basophils.

13 Oct 2008 Macrophage-derived chemokine (MDC) CCL22 is a potent chemoattractant for Th2 cells and has been implicated in Th2-predominant allergic inflammation. In the present study, we demonstrated that basophils produce MDC in response to monomeric IgE. In ... Read more...
