“…For example, they produced an allochimeric protein (α1H u70-77-RT1.Aa) by superimposing the nucleotides encoding last four (His70, Val73, Asn74, and Asn77) of nine (Arg62, Glu63, Gln65, Gly66, Gly69, His70, Val73, Asn74, and Asn77) polymorphic amino acids in the α1helical region of donor-type RT1.Au onto the host RT1.Aa backbone using gene splicing and overlap extension. Intraportal injection of this allochimeric protein significantly prolonged the survival of Wistar-Furth (WF, RT1u) cardiac allografts in ACI (RT1a) rats (111,112). They have further used allochimeric proteins via the oral route to induce allo-specific tolerance (113).…”
