To evaluate morphological characteristics and development of the immune system at different ages in neonatal pigs, 4 piglets were euthanized at 7, 14, and 18 d of age for collection of blood, bile, and intestinal tissue for morphological measurements. Blood was collected for differential cell counts, lymphocyte blastogenesis, immunoglobulin (Ig) ... More

Three candidate cytokines: recombinant porcine interleukin-2 (rpIL-2), rpIL-6 and the fusion protein rpIL6-IL2 were used as adjuvants in this study to investigate the enhanced immune responses to PRV inactivated vaccine (IAV) in pigs. In this natural host trial, we demonstrated that rpIL-2 showed potential adjuvant effects on PRV IAV, which ... More
