The network of molecular mediators involved in the transmigration of leukocytes to inflamed tissues has been expanding with the identification of new molecules involved in the inflammatory response. We have previously shown using a rat model that Protein Disulfide Isomerase PDIA4 (ERP72) is involved in the inflammatory response to skeletal muscle traumatic injury. In this paper, we report observations suggesting that calsequestrin 2 (CASQ2), another member of the thioredoxin/PDI family, might contribute to the inflammatory response that leads to adhesion and transmigration of leukocytes into injured skeletal muscle. Indeed, real time PCR assay showed that the expression level CASQ2 is significantly enhanced [p2+ buffering role of CASQ2 suggest that the protein contributes to the inflammatory process by providing the Ca2+ needed to activate the inflammasome and the leukocytes adhesion molecules which enhances transmigration of inflammatory cells into the injured muscle. |
