Plasmacytoid dendritic cells are dispensable or detrimental in murine systemic or respiratory viral infections - Nature Immunology Previous research has suggested that pDCs are required for an effective antiviral immune response, but direct experimental evidence to support this is lacking. Here Ngo et al. develop a pDC knockin mouse model and find that pDCs are dispensable for an antiviral immune response to mouse cytomegalovirus and may be detrimental during influenza or SARS-CoV-2 infection.

E. Tomasello & team at @ciml.bsky.social challenge the prevailing dogma of plasmacytoid DC's role in anti-viral immunity, by showing that they are deleterious in respiratory viral infections.
