Figure 2.

Effect of LeTx (2 µg·g⁻¹, i.p., 18 h) on intracellular Ca²⁺ homeostasis in cardiomyocytes from WT and TLR4^−/− mice. (A) Resting fura-2 fluorescence intensity (FFI). (B) Electrically-stimulated rise in FFI (ΔFFI). (C) Intracellular Ca²⁺ transient decay rate (single-exponential). (D) Intracellular Ca²⁺ transient decay rate (bi-exponential). Mean ± SEM, n= 60–75 cells from three mice per group, *P < 0.05 versus WT group, #P < 0.05 versus WT-LeTx group.
