IFNAR1 and infection: Cultures of myelinating cells from the CNS and from the peripheral nervous system (PNS) of wild-type mice and mice knockout to Ifnar1 (interferon alpha and beta receptor subunit 1) were infected by ZIKV to examine the neuronal and glial tropism of ZIKV and the short-term consequences of a direct infection with the Brazilian variant of ZIKV (Cumberworth et al., 2017).
