Abstract: Mast cells and basophils express high amounts of Fc?RI. In basophils the concentration of anti-IgE or antigen required for maximal histamine release through Fc?RI varies among donors, a concept termed “releasability.” Some donors fail to release histamine in response to any concentration of IgE-mediated stimulus (nonreleaser)1, 2, 3, 4 and were subsequently found to lack the protein tyrosine kinase Syk.5 Although the nonreleaser phenoytpe is common (ie, present in 10% to 20% of all donors), it is not known whether mast cells exhibit a similar IgE-mediated nonresponsiveness. We report here a lung mast cell preparation that did not respond to IgE-mediated stimuli.
