Does overexpression of interleukin-1 receptor antagonist provide cardioprotection against ischemia-reperfusion injury associated with reduction in apoptosis?
IL-1ra introduced by gene transfection protected myocardium from I/R injury by attenuating the inflammatory response, which was associated with decreased apoptosis. This suggests a potentially important role of IL-1/IL-1ra in myocardial I/R injury and the value of IL-1ra-gene therapy for myocardial preservation.
We conclude that: (1) children with sickle cell hemoglobinopathies 10 years or older should be screened for MA and (2) chronic transfusions starting at an early age may be renoprotective.
