WebAug 13, 2024 · The IRF7 deficient pDC was severely impaired for type I or type III IFN production in response to influenza A virus infection 25. Moreover, an increased viral replication and reduced type I IFN production was observed for IRF7-deficient fibroblast or pulmonary epithelial cells in culture. In marked contrast to earlier observations, our data ... WebNov 17, 2024 · Plasmacytoid dendritic cells (pDCs) are the key producers of type I interferons (IFNs), thus playing a central role in initiating antiviral immune response.
