The origin of the primary membrane of the vaccinia virus, a double-membrane structure that surrounds the immature virions (IV), is not fully understood. Here we investigated whether the primary membrane originates from the autophagic membrane. Morphologic studies by electron microscopy (EM) showed no apparent difference in viral maturation in the autophagy-deficient cell lines, the otg5(-/-) mouse embryonic fibroblasts (MEFs) and the beclin1(-/-) embryonic stem (ES) cells, compared to their isogenic wild-type counterparts. Moreover, viral growth curves demonstrated that vaccinia viruses replicate and mature in the autophagy-deficient cell lines as efficiently as they do in their isogenic wild type counterpart cells. This study indicates that the cellular autophagy machinery is not required for the life-cycle of vaccinia virus, suggesting that the primary vaccinia viral membrane does not originate from the autophagic membrane.
