PTPRC and Hypoalbuminemia: Both CD45 (Fig. 5A) and FSP1 (Fig. 5B) showed a pericentral staining pattern, similar to the pericentral necrotic lesions shown in Fig. 4B. Taken together, hypoalbuminemia aggravates OTA hepatotoxicity with a zonated damage pattern in the pericentral compartment of the liver lobule.
