Abstract
The addition of low concentrations of phorbol 12-myristate 13-acetate to rabbit neutrophils induces cell aggregation, degranulation, increased oxygen consumption and an increase in the amount of actin associated with the cytoskeleton without a rise in the level of intracellular free calcium as measured using the fluorescent probe quin-2. The ability of phorbol 12-myristate 13-acetate to initiate neutrophil responses similar to those produced by the chemotactic factor without causing a rise in the level of intracellular free calcium suggests two possibilities; that there is a second messenger in addition to calcium or that it activates the cells at a point distal to calcium mobilization. The possible role of diacylglycerol in neutrophil activation is discussed.
