He figure represents one of at least three individual experiments.pretreated with BAPTA/AM or TG for 1 h and then exposed to LTA (50 g/ml) for the indicated time intervals. As shown in Figure 5A, LTA-stimulated CaMKII phosphorylation was significantly inhibited by pretreatment with BAPTA/AM (30 M, upper panel) or TG (1 M, lower panel) during the period of observation, suggesting that LTA stimulate
