IFNG and infection: In remote TBI (≥3 years since infection) IFN-γ response to Rv2628 for short (1-day) and long (7-day) incubation intervals were significantly higher than in recently infected individuals (≤3 months since infection), but no significant difference was found after stimulation with Rv2626c, Rv2627c, Rv2031c, and Rv2032.
