Notably, we selected analytes that demonstrate elevated expression in TB patients compared to household contacts or controls, classify disease severity or susceptibility in preclinical models of infection, or are elevated in cases of recurrence, including: CXCL5 (ENA-78) [32,33], GM-CSF [34,35], IL-1β [28,36], IL-2 [32,35], IL-2RA [37,38], IL-5 [39], IL-6 [28,40,41], IL-9, IL-12p70 [42], IL-13 [35], IL-15/15R [43], IP-10 (CXCL-10) [35,40,43], MCP-1 [43], MIP1-β [35], and TNFα [36,37,40]. This evidence concerns the gene IL5 and infection.
