CXCL10 and infection: Conversely, correlations between IL-10, IP-10, TNF-α and sIL-2Rα and VL remained significant but they were only associated with baseline VL and not with 6-month and 12-month VL, which suggests that these molecules may not have any predictive value over the course of infection but they would only be related to the level of concurrent viral replication.
