The localization and quantification of CD172a
cells in equine nasal mucosa. The distribution (A) and the number (B) of CD172a+ cells in mock inoculated and EHV-1 neurological strain 03P37 and abortigenic strain 97P70 inoculated nasal mucosa at 0, 24, 48 and 72 hpi. C The percentage of EHV-1 infected cells in the population of CD172a+ cells in the nasal mucosa. ROIWI is the region including the epithelium and the lamina propria with EHV-1 infection in the epithelium whereas ROIWOI is the region without EHV-1 infection in the epithelium (two-way ANOVA; *P < 0.05; **P < 0.01). EHV-1 infected cells (red); CD172a+ cells (green). The white line drawn on the image represents the BM. Scale bar: 50 µm.
