Abstract
CpG oligodeoxynucleotides (ODN) were identified that stimulated immunoglobulin production and cell proliferation in cotton rat cells in vitro. Three of these ODN were used as a mucosal adjuvant in the noses of cotton rats immunized via this route with respiratory syncytial virus fusion (F) protein. The CpG ODN markedly increased the cotton rat humoral neutralizing-antibody response to respiratory syncytial virus. Such immunized animals had a marked reduction in the production of infectious virus after a live-virus challenge. Animals immunized with the combination of F protein and CpG developed enhanced pulmonary pathology consisting of alveolitis and interstitial pneumonitis after a live-virus challenge. Similar enhanced disease has been seen in cotton rats and children immunized with formalin-inactivated respiratory syncytial virus.Entities:
