Anti-CCL2-conjugated platelets attenuate early allograft and ischemia-reperfusion injury by inhibiting monocyte infiltration

Listen to this summary

The authors investigate the role of CCL2-CCR2 signaling in early allograft dysfunction and its contribution to inflammatory injury and rejection in liver transplantation. They develop a platelet-based drug delivery system conjugated with anti-CCL2 antibodies (PLT-aCCL2) to inhibit monocyte infiltration and mitigate these adverse effects. The study demonstrates that targeting this signaling pathway can protect liver allografts by disrupting the immune-inflammatory cascade and reducing interactions between monocytes and T cells.
