    PRRSV-2 infection activates the RIG-I/MAVS and canonical NF-κB pathways, which in turn upregulate RAB18 expression. RAB18 recruits PLIN2 through direct interaction with HSPA8 and thereby translocates PLIN2 to the lysosome for CMA-mediated degradation. Neutral lipases, such as ATGL, stimulate lipolysis, facilitating PRRSV-2 replication and assembly.
