The airway epithelium poses a formidable barrier for the entry of pathogenic viruses due to the formation of tight junctions between adjacent epithelial cells. The coxsackievirus and adenovirus receptor (CAR), a member of the Ig superfamily of cell junction adhesion proteins, is the primary receptor for adenovirus entry and infection. As a result of alternative splicing, two transmembrane isoforms of CAR are generated. While the seven-exon isoform of CAR (CAREX7) is hidden on the basolateral surface of polarized epithelia, the eight-exon isoform of CAR (CAREX8) localizes within the sub-apical region and at the air-exposed apical surface. …

A major factor in virus entry into cells is localization and abundance of the primary receptor. The Coxsackievirus and adenovirus receptor (CAR) is the primary receptor for group B coxsackievirus and many serotypes of adenovirus. In most epithelia, a seven exon isoform of CAR (CAREx7) is exclusively localized at the basolateral surface where it behaves as a homophilic adhesion protein and is inaccessible for viral infection. However, in well-differentiated human airway epithelia, we recently discovered an alternatively spliced, low abundance isoform of CAR (CAREx8) that is apically localized where it may initiate apical viral infection. The …
