ROLE OF MAST-CELLS IN ANAPHYLAXIS - EVIDENCE FOR THE IMPORTANCE OF MAST-CELLS IN THE CARDIOPULMONARY ALTERATIONS AND DEATH INDUCED BY ANTI-IGE IN MICE JOURNAL OF CLINICAL INVESTIGATION Martin, T. R., GALLI, S. J., Katona, I. M., Drazen, J. M. 1989; 83 (4): 1375-1383

Abstract

We used genetically mast cell-deficient WBB6F1-W/Wv and WCB6F1-S1/S1d mice and the congenic normal (+/+) mice to investigate the effects of intravenous infusion of goat antimouse IgE on heart rate (HR), pulmonary dynamic compliance (Cdyn), pulmonary conductance (GL), and survival. In WBB6F1-+/+ and WCB6F1-+/+ mice, anti-IgE induced extensive degranulation of tracheobronchial mast cells, as well as significant elevation of HR, significant reductions in Cdyn and GL and, in some cases, death. In contrast, W/Wv and S1/S1d mice exhibited little or no pathophysiological responses and no mortality after challenge with anti-IgE. In W/Wv mice reconstituted with mast cells by intravenous administration of bone marrow cells derived from congenic +/+ mice (+/+ BM----W/Wv mice), anti-IgE induced extensive mast cell degranulation, as well as pathophysiological responses and mortality similar to those observed in WBB6F1-+/+ mice. These findings suggest a critical role for mast cells in the development of the cardiopulmonary changes and mortality associated with anti-IgE-induced anaphylaxis.
