IGFBP3 and tuberculosis: The present study aims to compare the expression of these proteins previously described as plasma host markers related to TB, CLEC3B, SELL, IGFBP3, IP10, CD14, ECM1 and C1Q, in different human clinical groups (ATB, TBI, and HD) and during anti-TB treatment to identify a putative host protein signature useful for both TB diagnosis and treatment monitoring.
