Abstract EN
Background.
Neuroinflammation plays a key role in myocardial ischemia-reperfusion (I/R) injury.
Previous studies showed that light-emitting diode (LED) therapy might improve M2 microglia activation and brain-derived neurotrophic factor (BDNF) expression, thereby exerting anti-inflammatory effects.
Therefore, we hypothesized that LED therapy might reduce myocardial I/R injury by neuroinflammation modulation.
Objective.
To explore the effect of LED therapy on myocardial I/R-induced injury and seek the underlying mechanism.
Methods.
Thirty rats were randomly divided into three groups: Control group (without LED treatment or myocardial I/R, n=6), I/R group (with myocardial I/R only, n=12), and LED+I/R group (with myocardial I/R and LED therapy, n=12).
Electrocardiogram was recorded continuously during the procedure.
In addition, brain tissue was extracted for BDNF, Iba1, and CD206 analyses, and heart tissue for myocardial injury (ischemic size and infarct size), IL-4 and IL-10 mRNA analysis.
Results.
In comparison with the I/R group, the ischemia size and the infarct size were significantly attenuated by LED therapy in the LED+I/R group.
Meanwhile, the microglia activation induced by I/R injury was prominently attenuated by LED treatment either.
And it is apparent that there was also an increase in the beneficial neuroinflammation markers (BDNF and CD206) in the paraventricular nucleus (PVN) in the LED+I/R group.
Furthermore, the anti-inflammatory cytokines, IL-4 and IL-10, were greatly decreased by I/R while improved by LED treatment in myocardium.
Conclusion.
LED therapy might reduce neuroinflammation in PVN and decrease myocardium injury by elevating BDNF and M2 microglia.
