T cell responses to influenza virus infection

The specter of a pandemic caused by avian influenza virus highlights the need to identify possible mechanisms of immune protection from emerging strains of the flu virus. We cannot accurately predict which influenza will emerge as the next pandemic, making it difficult to select and manufacture sufficient conventional vaccine to elicit protective homotypic antibodies. Protective T cell mediated heterosubtypic immunity to influenza is an established paradigm in animal models, but is not well documented in humans. Though it is likely that heterosubtypic immunity to influenza exists in humans, there is little evidence of its specificity, and the reasons why it may or may not be protective are unclear. Our lab has shown that optimal CD8 T cell mediated heterosubtypic immunity is provided when T cells are retained in the lung tissue and airways via their interaction with collagen via the VLA-1 collagen receptor (Ray et al., 2004). One hypothesis is that heterosubtypic immunity to influenza fails in humans because of insufficient memory in the lung tissue. Having these T cells in place would not prevent infection, but could limit the duration and magnitude of viral replication. This could be the difference between life and death when encountering an emerging pandemic strain of influenza. Conventional influenza subunit vaccination is designed to generate antibodies, and does not strongly stimulate tissue-memory. Future strategies for influenza vaccine design should target both antibodies and cross-reactive lymphoid and tissue memory T cells. Our goals are to better understand potentially heterosubtypic immune responses to influenza and begin to develop the means to evaluate and, in the future, promote optimal vaccination strategies. To accomplish these goals, the Topham lab has established assays for detailed analysis of cell-mediated immunity (CMI) against influenza in humans, and has developed improved animal models for studying CD4 T cell mediated influenza immunity in mice. Comprehensive assay systems are established to target CD4 and CD8 T cells, and B cells responding to influenza virus, viral hemagglutinin, or influenza vaccines.
