To enhance the specificity of anti-TNF-α single chain Fv antibody (TNF-scFv) to inflamed site, we constructed a bispecific antibody BsDb that targets TNF-α and ED-B-containing fibronectin (B-FN) by covalently linking TNF-scFv and the anti-ED-B scFv L19 at the gene level via a flexible peptide linker deriving from human serum albumin. BsDb was successfully secreted from Pichia pastoris as functional protein, identified by immunoblotting, and purified to homogeneity with affinity chromatography. BsDb retained the immunoreactivity of its original antibodies TNF-scFv and L19, and showed a marked gain in antigen-binding affinity and in TNF-α-neutralizing ability, when compared to TNF-scFv and L19 that were produced in Escherichia coli. In the adjuvant-induced arthritis (AIA) mice model, BsDb showed selective accumulation and retention in the inflamed paws but rapid clearance from blood, resulting in high arthritic paw to blood ratios. These data indicate that BsDb is endowed with high specificity to inflamed site and low toxicity to normal tissues and holds great potential for in vivo application for the targeted therapy of RA and other chronic inflammatory diseases.

Aim To explore the mechanism of E.coli heat-labile enterotoxin B subunit(LTB)as adjuvant by analysis of cellular proteins interacting with LTB. Methods Whole cell proteins were purified from RAW 264.7 cell after treated with LTB or NaCl 12 h, respectively.The cellular proteins were interacted with LTB and the interacting proteins were purified by pull-down assay and identified by mass spectrography.The LTB interaction proteins were conformed with Western blot and immunofluorescence assay.Results 25 LTB interaction proteins were found,and their interaction network was mapped;four proteins (Jup,Dsp,Ddx5 and Vimentin)were indicated to be related with LTB adjuvant activity;immunofluorescence assay indicated that GM130 interacted with LTB,however,Vimentin had no interaction with LTB in vivo.After treated by LTB,the expression of β-actin was upregulated obvi-ously in RAW 264.7 cell,whereras,Hspd1 did not show any change.Conclusions LTB exerts adjuvant activity through binding to GM1 of immune cells,cau-sing endocytosis and transporting to the Golgi apparatus by vesicles.Then LTB might bind to Jup and affect TCF/LEF activity,regulating the expression of Bcl 2, IL-6,and Runx3.The result is promoted T cell and B cell proliferation,differentiation and activation by se-cretion of cytokines and immunoglobulins.
