| Research Abstract |
In this study, we studied about the molecular targeting using phage display library, particularly, on the characterization of two peptide mimics and three human scFv antibodies as candidates for human therapeutic reagents.
1)Establishment of peptide antagonists and human antibodies for therapeutic purpose
2)Development of low molecular forms of human antibodies
3)Development of novel biofunctional molecules by antibody engineering
Regarding 1) : we established anti-prion scFv, anti-amyloid beta scFv and anti-IL-18 antibodies which are useful for human diagnostic and therapeutic approaches.
Regarding 2) : In the case of anti-amyloid beta, we successfully established the amyloid beta-specific VI fragment with the inhibitory activity of amyloid fiblilization.
Regarding 3) : we attempted to study the methodology for the affinity maturation of scFv using AID (activation-induced cytidine deaminase) activity in hybridomas. In this study, we examined the transfection efficiency of AID to hybridomas using various gene transfection methods such as adenovirus vector, retrovirus vector, usual electrophoretical DNA transfection or lipofectamine-transfection
