Figure Lengend Snippet: Fig. 9 Diagram of the interplay between activated platelets and neutrophils in PTS and the function of HMGB1. HMGB1 is released from neurons and glia during the acute phase after PTS. This released HMGB1 accumulates within blood vessels, activating platelets and inducing NETosis. Activated platelets release HMGB1, further amplifying NETosis. Platelets adhere to the endothelium and interact with NETs, trapping circulating procoagulant factors and red blood cells (RBCs). This leads to the formation of neutrophils-platelets aggregates, where HMGB1 derived from both activated platelets and NETosed neutrophils likely plays a critical role. Administration of BBCA or HMGB1 A box can suppress this process. HMGB1, High mobility group box 1; BBCA, BB-Cl-amidine; RBCs, red blood cells
