The levels of 12 VZV structural proteins, including capsid proteins (pORF23 and pORF40), tegument proteins (pORF7, pORF9, pORF47, pORF62, and pORF63), and glycoproteins (gE, gB, gH, gI, and gN) were examined by western blotting at two and four days post-infection (dpi) among different infections. The gene discussed is ART4; the disease is infection.
