Figure 6

Comparison of inhibitory junction potentials (IJPs) evoked by 10 Hz EFS recorded in vitro in the presence or absence of morphine (10−5 M) from WT (A) and TLR2/4−/− (B) distal colon preparations. A graph summary showing the mean amplitude of fast (C) and slow (D) component of IJPs from WT (black bars) and TLR2/4−/− (white bars) in the absence or presence of morphine (10−5 M).
