Overview
Pathogenesis
Enterovirus 68 belongs to the Human Enterovirus D species (HEV-D), along with EV-70 and EV-94. Unlike the remaining, EV-69 is acid-labile, which reduces its ability to colonize the gastrointestinal mucosa. It has therefore been implicated in respiratory infections, and in rare occasions in CNS infection. This characteristic of EV-68 sets it apart from other enteroviruses, in what deals with its pathogenesis and infected cells.[1]
Besides cells of the respiratory mucosa, EV-68 also shows tropism for leukocytes, using the receptors that contain sialic-acid in these cells.[2]
