Skin biopsy samples from varicella-zoster virus (VZV)-infected
patients examined by immunohistochemistry demonstrated VZV replication
in nonepithelial cell types. ORF29p, a nonstructural nuclear protein,
was found in nerves of two of six patients with chickenpox. In tissue
culture, ORF29p was secreted by VZV-infected fibroblasts. Extracellular
ORF29p can be taken up through endocytosis by human neurons, implying a
novel role for this protein in pathogenesis.
