Abstract: Exercise is an effective measure for preventing and treating cardiovascular diseases, although
the exact molecular mechanism remains unknown. Previous studies have shown that both
irisin and exosomes can improve the course of cardiovascular disease independently. Therefore, it
is speculated that the cardiovascular protective effect of exercise is also related to its ability to regulate
the concentrations of irisin and exosomes in the circulatory system. In this review, the potential
synergistic interactions between irisin and exosomes are examined, as well as the underlying
mechanisms including the AMPK/PI3K/AKT pathway, the TGFβ1/Smad2/3 pathway, the
PI3K/AKT/VEGF pathway, and the PTEN/PINK1/Parkin pathway are examined. This paper provides
evidence to propose that exercise promotes the release of exosomes enriched with irisin,
miR-486-5p and miR-342-5p from skeletal muscles, which results in the activation protective networks
in the cardiovascular system. Moreover, the potential synergistic effect in exosomal cargo
can provide new ideas for clinical research of exercise mimics.
