We studied cytokine responses to influenza virus PR8 (H1N1) and Oklahoma/309/06
(OK/06, H3N2) in a novel human lung tissue model. Exposure of the model to
influenza virus rapidly activated the mitogen-activated protein kinase signaling
(MAPK) pathways ERK, p38 and JNK. In addition, RNase protection assay
demonstrated the induction of several cytokine and chemokine mRNAs by virus. This
finding was reflected at the translational level as IL-6, MCP-1, MIP-1
alpha/beta, IL-8 and IP-10 proteins were induced as determined by ELISA.
Immunohistochemistry for IP-10 and MIP-1 alpha revealed that alveolar epithelial
cells and macrophages were the source of these two cytokines. Taken together,
both PR8 and OK/06 cause similar induction of cytokines in human lung, although
OK/06 is less effective at inducing the chemokines MCP-1 and IL-8. This human
organ culture model should thus provide a relevant platform to study the
biological responses of human lung to influenza virus infection.
