Abstract:
The changes in levels of inositol phosphates and phosphoinositides were studied in the bovine lymphocytes, in response to phytomitogens (lectins)-concanavalin A (con A) and phytohaemagglutinin (PHA). Addition of con A and PHA resulted in a rapid increase in the cpm of total inositol phosphates (from 8599 +/- 100 cpm/2 x 10(6) cells to 11228 +/- 126 cpm/2 x 10(6) and 9758 +/- 100 cpm/2 x10(6) cells, respectively) at 1 min after mitogen stimulation. There was a concomitant decrease in the phosphatidylinositol levels at 1 min, which continued up to 5 min. At 1 min of stimulation, inositol diphosphate fraction exhibited maximum increase, as compared to inositol mono- and triphosphates, suggesting that it contributed the most towards the overall increase in the total inositol phosphates levels. Results suggest that bovine lymphocytes respond to phytomitogens with a rapid turnover of phosphoinositides.
