IFNG and tuberculosis: Interferon gamma-induced protein 10 (IP-10), a 7.2-kilodalton chemokine, could express 100-fold higher levels than IFN-gamma after TB infection.[9,15] The individuals’ age, gender and TB presentation do not affect the level of IP-10.[14–16] In recent years, many studies have reported that IP-10 has been identified as a sensitive parameter in detecting children TB.[9,17,18]
