The role of HDAC6 in ciliary disassembly has been extensively studied over the past decades [22,27,48,49], and increasing attention has been directed toward its involvement in viral infections [24,25], including ZIKV [25], IAV [46], porcine reproductive and respiratory syndrome virus (PRRSV) [50], porcine circoviruses 2 (PCV2) [51], and FMDV [52]. Here, HDAC6 is linked to viral infectious disease.
