Figure 9. BDNF effects on the surface expression of the δ subunit were mediated through activation of PLCγ.
A- Surface expression of the δ subunit was studied in the slices treated with BDNF for 6 hr in the presence of PLC inhibitor U73122 (5 μM) or PI3K inhibitor LY294002 (5 μM). Increased surface expression (S) of the δ subunit by BDNF was blocked by U73122 but not by LY294002. Total expression (T) of the δ subunit was similar in all the samples. B- Surface expression of the δ subunit after treatment with BDNF or BDNF and inhibitors (n=3–5, * p<0.05). C- A representative blot shows surface (S) and total (T) expression of the δ subunit was unaltered in slices treated with U73122.
