Recombinant hemagglutinin protein of rinderpest virus expressed in insect cells induces cytotoxic T-cell responses in cattle.
Rinderpest virus (RPV), a member of the genus Morbillivirus within the Paramyxoviridae family, causes a highly contagious and often fatal disease known as rinderpest in wild and domestic ruminants. The envelope of the virus contains two surface glycoproteins, namely the hemagglutinin (H) and the fusion (F) proteins, both of which have been shown to confer protective immunity in animals. In this paper, we demonstrate that single administration of low doses of recombinant H protein of RPV expressed in insect cells in the form of extracellular virus induces long lasting bovine leukocyte antigen class I restricted cytotoxic T-cell (CTL) responses in cattle in the absence of adjuvant. This is the first report of CTL responses in cattle against one of the protective antigens of RPV.
