Innate Immune Effectors Play Essential Roles in Acute Respiratory Infection Caused by Klebsiella pneumoniae

Figure 6

Depletion of innate immune effectors resulted in increased levels of cytokines/chemokines in K. pneumoniae lung infection. (a) The levels of IL-1β, IL-6, and TNF-α in the lung were detected by ELISA. (b) The levels of IL-1β, IL-6, and TNF-α in blood samples were detected by ELISA. (c) The levels of MCP-1, MIP-2, and CXCL-1 in lung samples were measured by ELISA. These assays were performed in triplicate, and representative data from one experiment were expressed as . Statistical analyses were performed by Student’s test.
