This study reveals that IP-10, induced by IFN-γ, serves as a crucial chemokine facilitating the transportation of immune cells to sites of inflammation, playing a pivotal role in the host’s defense against viral infections (11) Previous research suggests that IP-10 may serve as a key inflammatory factor predicting the severity of diseases caused by H7N9 avian influenza virus, respiratory syncytial virus, human immunodeficiency virus (HIV), and hepatitis B virus infections (12–15). The gene discussed is IFNG; the disease is hepatitis B virus infection.
