This study tested the hypothesis that 4-[(18)F]fluorophenyltriphenylphosphonium ((18)F-TPP) is useful for in vivo positron emission tomography (PET) measurement of mitochondrial membrane potential (ΔΨm). Its utility as a blood flow tracer also was evaluated. Tetraphenylphosphonium is useful for in vitro measurement

Plasma membrane depolarization activates the Rho/Rho kinase (ROK) pathway and thereby enhances myosin light chain (MLC) phosphorylation, which in turn is thought to be a key regulator of paracellular permeability. However, the upstream mechanisms that couple depolarization to Rho activation
