Fig. 10 Schematic illustration of the present study. After SAH (red arrow), endothelial cells and pericytes secrete CXCL12 (yellow arrow), facilitating the infiltration of CD8+ CXCR4+ T cells into the brain parenchyma (green arrow). These infiltrating T cells release perforin and granzyme B (purple arrow), inducing endothelial cell apoptosis and exacerbating BBB disruption. Blocking CXCL12-mediated T-cell infiltration with CXCL12 antibodies or AMD3100 (a CXCR4 antagonist, blue arrow) preserves BBB integrity and promotes neurological outcomes after SAH

Techniques:

The role and mechanism of SDF‐1 in hepatic IR were displayed. Up‐regulated SDF1 binds to its receptor CXCR4 and CXCR7 on hepatocytes following PA treatment. SDF‐1/CXCR4 signalling, not SDF‐1/CXCR7 signalling, inhibits lipophagy in hepatocytes via activating the phosphorylation of AKT and mTOR1 to promote PA‐induced IR. The blockade of SDF‐1/CXCR4/AKT/mTOR signalling‐induced lipophagy alleviates IR in PA‐treated hepatocytes.
