Meanwhile, the concentrations of procalcitonin (PCT) and C-reactive protein (CRP) were increased significantly compared with the control group (Fig. 1C, D) In the meantime, the PBMCs mRNA level of SLC38A6 expression was significantly up-regulated in patients with bacterial pneumonia compared with the control group (Fig. 1E). This evidence concerns the gene SLC38A6 and bacterial pneumonia.
