Fig 4. PLC and PI3K signaling in response to AgNPs.

Fig 4

Mast cell degranulation was assessed by measuring the release of β-hexosaminidase into supernatants. Cells were pre-treated with (A) the PLCγ inhibitor U73122 (1 μM) or (B) the PI3K inhibitor wortmannin (100 nM) 30 min prior to AgNP (25 μg/ml) exposure for 1 h and release of β-hexosaminidase was assessed. (C) Representative immunoblots for p-PI3K in samples pretreated with or without Blt-2 (50 μM) and followed by AgNP exposure for 1 h. Values are expressed as mean ± SEM of at least 3 independent experiments. *Indicates significant difference from controlled group (p≤0.05). #Indicates significant difference from AgNP-treated group (p≤0.05)
