HIV Encodes Several Proteins That Function to Promote Viral Replication $\kappa$

Multiple Choice

HIV encodes several proteins that function to promote viral replication, packaging, and budding from host CD4 T cells. In addition to inhibiting cell-intrinsic antiviral mechanisms and down-regulating surface expression of MHC class I and class II molecules, these proteins function to:

A) Induce constitutive activation of NF- $\kappa$ B
B) Promote nuclear localization of NFAT
C) Block nuclear export of unspliced viral RNA
D) Up-regulate surface expression of CD4
E) Induce robust, sustained CD4 T cell activation
