RBCs have also been proposed to induce vasodilation via other mechanisms

That's just a technical way of saying it's a chain of 15 amino acids

3.3 Downstream Signaling Effects Beyond actin sequestration, TB-500 influences several additional signaling pathways: Angiogenic Signaling through CD44 Interaction TB-500 binds to the CD44 cell surface receptor, activating downstream signaling cascades that include: MAPK/ERK pathway: Promotes endothelial cell proliferation PI3K/Akt pathway: Supports cell survival and migration MMP induction: Matrix metalloproteinase activation for extracellular matrix remodeling Integrin-Mediated Cell Adhesion The peptide upregulates integrin expression including v3 and 51, enhancing cell-matrix adhesion and facilitating cell migration across extracellular matrix substrates
