CXCL10 and infection: Levels of the chemokines CXCL9 (also known as monokine activated by IFN-γ, or MIG), CXCL10 (also known as interferon-inducible protein of 10 kD, or IP-10), and CCL4 (also known as MIP-1β) were measured at two- to ten-fold higher levels day 1 after infection with HSV-2/gD-Δ7-15 relative to HSV-2/gD (Fig. 7A–C); these differences did not persist at later times.
