In humans, infection by respiratory viruses (e.g., HRSV, coronavirus, and influenza A virus) regulates the expression of cellular receptors such as intercellular adhesion molecule-1 (ICAM-1), carcinoembryonic antigen-related cell adhesion molecule, fibronectin, and platelet-activating factor receptor (PAFR) (Garcia et al., 2010; Golda et al., 2011; Hendricks et al., 2016). This evidence concerns the gene PTAFR and infection.
