CXCL8 and infection: HTB-5/HMC-1 cells simultaneously infected with the CFT073ΔfimH strain at 5 h showed a similar pattern of IL-8 release as HMC-1 cells infected with the CFT073ΔfimH strain at 3 and 5 h; however, at 3 h after infection, IL-8 release was not restored in HTB-5/HMC-1 cells (Figure 2a).
