Calcium sensitivity and the Frank-Starling mechanism of the heart are increased in titin N2B region deficient mice

Previous work suggests that titin-based passive tension is a factor in the Frank-Starling mechanism of the heart, by increasing length-dependent activation (LDA) through an increase in calcium sensitivity at long sarcomere length. We tested this hypothesis in a mouse model (N2B KO model) in which ti...
