Abstract/OtherAbstract:
The t-tubule system in ventricular cardiomyocytes is essential for synchronous Ca(2+) handling, and therefore efficient contraction. T-tubular remodeling is a common feature of heart disease. In this review, we discuss whether t-tubular remodeling can be reversed and which factors may be implicated in this process. In particular, we focus on the interaction between mechanical load variation and t-tubule structure and function. What is the evidence of this relationship? What is the role of different degrees and durations of mechanical load variation? In what settings might mechanical load variation have detrimental or beneficial effects on t-tubule structure and function? What are the molecular determinants of this interaction? Ultimately this discussion is used to address the question of whether mechanical load variation can provide an understanding to underpin attempts to induce recovery of the t-tubule system. In reviewing these questions, we define what remains to be discovered in understanding t-tubule recovery.
