SARM1 and infection: To investigate any role SARM1 may play in ZIKV-induced death of neuronal processes, we infected CNS myelinating spinal cord cultures from wild type mice, or Sarm1 heterozygous or homozygous null mice (Kim et al., 2007) on a type I interferon receptor (Ifnar1) null background; the last to facilitate infection (Miner and Diamond, 2017).
