IFNA1 and infection: Analysis of beta-galactosidase distribution in ±20 neurons in either lytically infected neurons (2dpi in the absence of IFNalpha) or quiescently infected neurons (5dpi in the presence of IFNalpha) indicated that in lytically infected neurons, beta-galactosidase distribution was generally uniform throughout the neuronal cell body (Fig. 3Di, ii) and sometimes associated with spread of infection to surrounding non-neuronal cells (Fig. 3Di), while a more focal beta-galactosidase distribution was frequently found in quiescently infected neurons (Fig. 3Diii).
