upregulation of multiple proinflammatory markers in LC compared with CC group and uninfected, chemokines and cytokines (CXCL2, CXCL3, CCL3, IL10, IFNG, IL6, TNF, IL1B, IL1A, NFKBIZ),
NLRP3 inflammasome and complement and coagulation genes C5, F3 and THBS1. downregulation of activating (KLRC2) and inhibitory (KLRC1, KIR3DL2) natural killer (NK) cell receptors and T cell activation markers in LC compared to CC group.
differentially expressed genes in LC group compared with CC group at day 90–180 after pi-⬆️of multiple proinflammatory markers, such as IL6, NLRP3, TNF, JAK2, CSF2, IL1B, IL10, in the LC compared with CC group.
Pathway enrichment analysis revealed upregulation of signatures associated with signaling by proinflammatory cytokines such as IL-6, IFNα, IFNβ and IFNγ, JAK-STAT pathways, complement and coagulation cascade, metabolic pathways and immune cell signatures of monocytes, macrophages, neutrophils and dendritic cells ;
RNA processing and nitrogen metabolism, oxidative stress and amino acid transport, were decreased in the LC compared with the CC group ,
transcriptomic signatures of T cell activation and differentiation (CD28, ICOS, TCF7) were downregulated in the LC compared with the CC group at day 90–180 after infection.
CD8 T cell exhaustion signatures and programmed cell death protein 1 (PDCD1) signaling-associated genes (IFI44, PRDM1, NR4A3, NFKBIA, MAFF) were significantly increased in the LC group.
potential role of T cell dysregulation in the pathogenesis of LC. Moreover, JAK1, JAK-STAT and IL-6 signaling pathways correlated inversely with T cell activation and positively with CD8 T cell exhaustion and PD-1 signaling ;
Signatures of T cell activation and differentiation were positively correlated with IFNγ ELISpot responses, whereas proinflammatory signaling and immune exhaustion signatures were negatively correlated with IFNγ ELISpot responses. significant correlation between IL-6 and JAK-STAT signaling pathways with complement and coagulation pathways, metabolic signatures and PD-1 signaling in the LC group ;
potentially coordinated role of these pathways in the pathogenesis of LC, while the IL-6 and JAK-STAT signaling pathways correlated negatively with metabolism of amino acids and oxidative stress in LC.
IFNγ, IL-6, JAK-STAT and T cell exhaustion pathways correlated with clinical symptoms in group with LC, fatigue, shortness of breath, cognitive complaints.
