N2 - The immune mechanisms by which early host-mycobacterium interaction leads to the development of severe tuberculosis (TB) remain poorly characterized in humans. Here, we demonstrate that severe TB in juvenile rhesus monkeys downregulated many genes in the blood but up-regulated selected genes constituting gene networks of Th17 and Th1 responses, T cell activation and migration, and inflammation and chemoattractants in the pulmonary and lymphoid compartments. Overexpression (450-2740-fold) of 13 genes encoding inflammatory cytokines and receptors (IL-22, CCL27, MIP-1α, IP-10, CCR4, CCR5, and CXCR3), immune dysfunctional receptors and ligands (PD1 and PDL2), and immune activation elements (IL-3, IFN-β, TIM1, and TLR2) was seen in tissues, with low antigen-specific cellular responses. Thus, severe TB in macaques features unbalanced up-regulation of immune-gene networks without proportional increases in antigen-specific cellular responses.
