Lipoteichoic acid induces delayed myocardial protection in isolated rat hearts: A comparison with endotoxin

We conclude that preconditioning with LTA and likewise with LPS confers myocardial protection in an ex vivo setting devoid of leukocytes. Dexamethasone inhibits preconditioning, suggesting that the underlying mechanism is dependent upon induction of a systemic inflammatory response to a LTA or LPS stimulus.
