Abstract:
During severe influenza A virus (IAV) infections, a large amount of damage to the pulmonary epithelium is the result of the antiviral immune response. Specifically, whilst CD8(+) T cells are important for killing IAV-infected cells, during a severe IAV infection, they can damage uninfected epithelial cells. At present, the mechanisms by which this occurs are unclear. Here, we used a novel in vitro coculture model of human NCl-H441 cells and CD8(+) T cells to provide a new insight into how CD8(+) T cells may affect uninfected epithelial cells during severe IAV infections. Using this model, we show that human IAV-specific CD8(+) T cells produce soluble factors that reduce the barrier integrity of noninfected epithelial cells (referred to as "bystander damage"). We show that this bystander damage is the result of a combination of TNF-alpha and IFN-gamma. This bystander damage occurred in the absence of widespread epithelial cell death and was instead associated with decreased expression of epithelial cell ion channels and pumps. Together, these data suggest that ameliorating the function of epithelial cell ion channels and pumps may help reduce immunopathology during severe IAV infections.
