Influenza infection causes an increase in indoleamine 2, 3-dioxygenase (IDO)
activity in the lung parenchyma. IDO catabolizes tryptophan into kynurenine,
leading to immune dampening. Multiple cell types express IDO, and while IFN-?
upregulates IDO in dendritic cells and macrophages, it is unclear how IDO is
affected in respiratory epithelial cells during influenza infection. In this
study, the role of IFN-? in IDO regulation was investigated after influenza
infection of respiratory epithelial cells. IDO1 expression increased concurrently
with IFN-? expression. In differentiated NHBE cells, the IDO metabolite was
released basolaterally. Recombinant IFN-? upregulated IDO1 activity, and
silencing of IFN-? decreased IDO1 expression during influenza infection. During
IFN-? stimulation, most differentiated cell types are able to express IDO but
during influenza infection, IDO is primarily expressed in uninfected cells. These
studies show a role for IDO in the host response to influenza infection, and they
provide insights into novel approaches for enhancing vaccine responses and
therapeutic approaches.
