| Research Abstract |
Results of the Project
1.Both humoral and cell-mediated immune responses were depressed in Mycoplasma Pulmonis ( M. pulmonis )-infected DBA/2 mice 2 to 6 weeks after infection.
2.Antibody responses to sheep red blood cells were augmented in M. pulmonis-infected athymic BALB/C nude( nu/nu ) mice 1 to 4 weeks after infection.
3.About 30 hybridoma clones which produce monoclonal antibodies to M. pulmonis were obtained.
4.Among the monoclonal antibodies to M. pulmonis, 2 monoclonal antibodies were found to have the ability to inhibit slightly the formation of lung lesions caused by M. pulmonis infection.
5.Sera obtained from M. pulmonis-infected mice were found to have the ability to inhibit significantly the formation of lung lesions caused by M. pulmonis infection.
6.About 15 hybridoma clones which produce monoclonal antibodies to Sendai virus ( HVJ were obtained. Among the monoclonal antibodies to Sendai virus, none of them were found to have the ability to protect animals from Sendai virus infection.
7.Many hybridomas which produce antibodies to streptococcal erythrogenic toxin were obtained, but the cloning of the hybridomas has not yet been performed.
Future Aspects of the Project
1.Monoclonal antibodies to various pathogenic agents in laboratory animals will be produced. Anti-idiotype antibodies (preferably monoclonal anti-idiotype antibodies) to those monoclonal antibodies will be produced and applied as vaccine.
2.Hybridoma clones which produce monoclonal antibodies to streptococcal erythrogenic toxin will be produced.
