Rat Peritoneal Mast Cells

Histamine secretion and phosphatidylinositol turnover were compared in antigen-sensitized rat peritoneal mast cells stimulated with a number of different ligands. A small and variable increase in the incorporation of [32P]Pi and of [3H]inositol into phosphatidylinositol was observed when the cells were treated with immunoglobulin E-directed ligands (antigens and concanavalin A), and this was accompanied by a low amount of secretion (<10% of total cell histamine). In the presence of added phosphatidylserine, the addition of immunoglobulin E-directed ligands invariably led to an enhanced rate (approx. 4-fold) of labelling of phosphatidylinositol and, in the presence of Ca2+, this was accompanied by the secretion of histamine. The labelling of phosphatidylinositol and histamine secretion were also stimulated by chymotrypsin and compound 48/80. Whereas the phosphatidylinositol response did not require the presence of extracellular Ca2+, the secretion of histamine was either enhanced or dependent on extracellular Ca2+ (depending on the ligand used). The dependence on ligand concentration for the phosphatidylinositol response and histamine secretion were similar. The increased isotopic incorporation into phosphatidylinositol continued for about 1h although histamine secretion (elicited with concanavalin A) stopped within 2min. These results support the proposition that metabolic events involving phosphatidylinositol play a necessary intermediate role in the regulation of Ca2+ channels by ligand-activated receptors.
