Background: Recently, modification of T cells with chimeric antigen receptor (CAR) has been an attractive approach for adoptive immunotherapy of cancers. Typically, CARs contain a single-chain variable domain fragment (scFv). Most often, scfvs are derived from a monoclonal antibody of murine origin and may be a trigger for host immune system that leads to the T-cell clearance. Nanobody is a spe...
Schistosomiasis is one of the most prevalent parasitic diseases in China, and hepatic fibrosis caused by schistosome infection is the principal cause of death. The aim of this study was to evaluate the efficacy of NP11-4-derived immunotoxin scFv-artesunate on Schistosoma japonicum-induced hepatic fibrosis. A single-chain variable fragment (scFv) was generated from the murine anti-Schistosoma ja...
Chimaeric toxins have considerable therapeutic potential to treat various malignancies. We have previously used the fungal ribonucleolytic toxin restrictocin to make chimaeric toxins in which the ligand was fused at either the N-terminus or the C-terminus of the toxin. Chimaeric toxins containing ligand at the C-terminus of restrictocin were shown to be more active than those having ligand at t...
Viral protein neutralizing antibodies have been developed but they are limited only to the targeted virus and are often susceptible to antigenic drift. Here, we present an alternative strategy for creating virus-resistant cells and animals by ectopic expression of a nucleic acid hydrolyzing catalytic 3D8 single chain variable fragment (scFv), which has both DNase and RNase activities. HeLa cell...
We demonstrated previously that the switch from nonmetastatic to highly metastatic phenotype of human melanoma cells is directly related to secretion of procathepsin L form. This cysteine proteinase was identified on the basis of its property to cleave human C3, the third component of complement. In an attempt to control procathepsin L secretion, we have recently generated an anti-cathepsin L s...
Fibroblast growth factor receptor-1 (FGFR-1) transduces proangiogenic and proliferative signals in human cancers. Thus, FGFR-1may represent a target for the development of antiangiogenic/antineoplastic therapies. We screened a human single-chain fragment variable (scFv) antibody phage display library against the extracellular domain of the FGFR-1-IIIc isoform that harbors the FGF binding site. ...
