Illustration of the multifaceted 5-HT responses following inflammatory PRP-platelet activation. After platelet activation, platelets release their granules, including 5-HT from dense granules, inciting a wide range of differential effects on various immune, endothelial, and smooth muscle cells. Abbreviations: SMC: smooth muscle cell, EC: endothelial cell, Treg: regular T lymphocyte, MΦ: macrophage, DC: dendritic cell, IL: interleukin, IFN-γ: interferon gamma.
