We found that lnc-ANKRD37-1, lnc-CDC6-3, lnc-C5-1, lnc-BIRC3-1 and lnc-RP11-582J16.5.1-2 were upregulated in all of these three cell lines (by ≥2-fold) (Figs 5A and 7A,C), but exhibited responses of various intensities to meningitic E. coli infection. Here, C5 is linked to escherichia coli infection.
