Description |
The knee joint has long been considered a closed system. The pathologic effects of joint disease on distant organs have not been studied. Here, our clinical data showed that post-traumatic joint damage combined with joint bleeding (hemarthrosis) caused worse liver function compared to healthy control. Using a mouse model, hemarthrosis induces both cartilage degeneration and distant liver damage. Next, we found that hemarthrosis induces the upregulation in ratio and differentiation towards Th17 cells of CD4+ T cells in peripheral blood and spleen. Deletion of CD4+ T cells reversed hemarthrosis-induced liver damage. Degeneration of cartilage matrix induced by hemarthrosis upregulates serological type II collagen (COLII), which activates CD4+ T cells. Systemic application of a COLII antibody blocks this activation. Furthermore, bulk RNAseq and single cell qPCR analysis revealed that the cartilage Akt pathway is inhibited by blood treatment. Intra-articular application of Akt activator blocks cartilage degeneration and thus protects against liver injury in mouse and pig models. Taken together, our study revealed a pathological joint-liver axis mediated by matrikine-activated CD4+ T cells, which updates the organ-crosstalk axis and provides a new treatment target for hemarthrosis-related diseases. |
