Presence of virion protein x (Vpx) of simian immunodeficiency virus SIVmac 251 in target cells in vivo

J Med Primatol. 1995 Jan;24(1):35-42. doi: 10.1111/j.1600-0684.1995.tb00142.x.

Abstract

Localization of virion-associated protein x (Vpx) of SIVmac 251 was studied in lymph nodes and liver of six SIVmac-infected monkeys. Vpx was found associated with the network of follicular dendritic cells and macrophages in lymph nodes and/or livers from five out of six animals by immunohistochemistry. Although the humoral response to Vpx occurs in only 50% of the animals, the presence of Vpx in target cell or antibodies to Vpx in all the monkeys studied, suggests that Vpx may be necessary for viral replication in vivo.
