Opera and classical music reduce rejection in heart transplants performed in mice, according to the results of a study published in the Journal of Cardiothoracic Surgery .
Although music is already used in the clinical field to reduce anxiety after certain operations, the mechanisms by which music causes a change in brain function or its relationship with the immune system, responsible for rejection after surgery, are still unclear. transplants.
The researchers tested the effect of different types of music on how long the transplanted organ functioned without failure. While with opera and classical music the response was positive, the latest generation music did not achieve the same effect.
"The mice that listened to opera works such as La Traviata had a higher number of CD4 + CD25 + cells and anti-inflammatory cytokines, which regulate the peripheral immune response. This has as a consequence a greater survival of the graft", the study authors.
