CD14 and infection: To determine if incoming SH protein (i.e. within the virus particle) or SH protein induced after infection inhibits p65 phosphorylation, or if soluble mediators in the BRSVΔSH virus preparation were responsible for the increase in p65 phosphorylation, bovine CD14+ cells were infected as before in the presence of the translation inhibitor cycloheximide or were exposed to UV-inactivated virus.
