摘要： Porcine circovirus type2 (PCV2) is a member of the circoviridae family. PCV2 was identified as the main pathogen of postweaning multisystemic wasting syndrome (PMWS) in weaned piglets and causes massive economic loss. Basigin, is a transmembrane glycoprotein belonging to the immunoglobulin superfamily; which is also a receptor for cyclophilins. CyP belongs to the immunophilin family that has peptidyl-prolyl cis-trans isomerase activity. Basigin-CyP interaction affects the replication stages of several viruses. In this study, we found that Basigin could elevate the replication of PCV2, and the Basigin only affected the replication stage rather than adsorption or endocytosis stages. In addition, the ligands of Basigin, CyPA and CyPB also elevated the replication of PCV2. Basigin-CyP interation was necessary for elevating PCV2 replication; At last, CyPs were proved to promote the replication of PCV2 by activating ERK signaling.
