Characterization of primate bronchoalveolar mast cells. II. Inhibition of histamine, LTC4, and PGD2 release from primate bronchoalveolar mast cells and a comparison with rat peritoneal mast cells.
J Immunol. 1986 Dec 15; 137(12):3941-5.JI

Abstract

As described in the preceding companion paper, bronchoalveolar lavage (BAL) of the primate Macaca arctoides infected with the nematode Ascaris suum yields a population of cells containing a high proportion of mast cells (21%). Nedocromil sodium, a new drug undergoing clinical evaluation for the treatment of reversible obstructive airways disease, inhibited the release of histamine, LTC4, and PGD2 from these cells challenged with antigen (with IC30 values of 2.1 X 10(-6) M, 2.3 X 10(-6) M, and 1.9 X 10(-6) M, respectively) and with anti-human IgE (IC30 values of 4.7 X 10(-6) M, 1.3 X 10(-6) M, and 1.3 X 10(-6) M, respectively). Cromolyn sodium was essentially inactive. Histamine release from rat peritoneal mast cells induced by anti-rat IgE was, however, inhibited by both nedocromil sodium and cromolyn sodium with IC30 values of 1.1 X 10(-6) M and 5.5 X 10(-7) M, respectively. Both compounds induce phosphorylation of a 78,000 m.w. protein in the rat peritoneal mast cell in the absence of any stimulus at the same concentrations as those required to inhibit histamine release stimulated by anti-IgE. This event may be part of a feedback mechanism to limit degranulation. Nedocromil sodium and cromolyn sodium were equipotent in their ability to inhibit anti-IgE-induced histamine release from rat peritoneal mast cells, but differed markedly in their ability to inhibit histamine release from macaque BAL cells.
