Caveolae are flask-like invaginations of the plasma membrane enriched in
cholesterol, sphingolipids, the marker protein caveolin and the coat protein
cavin. In cardiomyocytes, multiple signaling molecules are concentrated and
organized within the caveolae to mediate signaling transduction. Recent studies
suggest that caveolae and caveolae-associated signaling molecules play an
important role in protecting the myocardium against ischemia-reperfusion injury.
For example, cardiac-specific overexpression of caveolin-3 has been shown to lead
to protection that mimics ischemic preconditioning, while the knockout of
caveolin-3 abolished ischemic preconditioning. In this review, we discuss the
molecular mechanisms and signaling pathways that are involved in
caveolae-mediated cardioprotection, and examine the potential for caveolae as a
therapeutic target for pharmaceutical intervention to treat cardiovascular
disease.
