Single-Chain Anti-IL-1β Antibody Carried by Outer Membrane Vesicles of Bacteroides fragilis Alleviates Tubular Inflammation in Chronic Kidney Disease. [PDF]

J Extracell Vesicles
Engineered Bacteroides fragilis outer membrane vesicles carrying anti‐IL‐1β scFv and kidney‐targeting peptides alleviate renal inflammation and injury in CKD mouse models via precise delivery and NF‐κB inhibition. ABSTRACT Microinflammation is a key driver of chronic kidney disease (CKD) progression, with interleukin‐1β (IL‐1β) playing a pivotal role ...

Chicken scFvs and bivalent scFv-CH fusions directed against HSP65 of Mycobacterium bovis [PDF]

Biologicals, 2010
Two chicken single-chain variable region antibody fragments (scFvs) that recognised the 65 kDa heat-shock protein (HSP65) of Mycobacterium bovis were selected from a large semi-synthetic phage displayed library. Both recognised HSP65 in indirect enzyme-linked immunosorbent assay (ELISA) and immunoblots and retained their activity during storage ...

Radiolabeling, Quality Control and In Vivo Imaging of Multimodal Targeted Nanomedicines

Pharmaceutics, 2022
Following our previous study on the development of EGFR-targeted nanomedicine (NM-scFv) for the active delivery of siRNA in EGFR-positive cancers, this study focuses on the development and the quality control of a radiolabeling method to track it in in ...

Intratumoral Delivery of a PD-1–Blocking scFv Encoded in Oncolytic HSV-1 Promotes Antitumor Immunity and Synergizes with TIGIT Blockade

Cancer immunology research, 2020
Oncolytic virus activity is often limited by an immunosuppressive tumor microenvironment. The antitumor efficacy of oncolytic herpes simplex virus is improved by delivering a single-chain variable fragment specific for PD-1.

Antibody-Mediated Resistance to Rhizomania Disease in Sugar Beet Hairy Roots

The Plant Pathology Journal, 2019
Agrobacterium rhizogenes–mediated transformation of sugar beet hairy roots expressing single-chain variable fragment (scFv) was exploited to evaluate the efficacy of four antibody-based constructs for interfering with the Beet necrotic yellow vein virus ...

Fv antibodies to aflatoxin B1 derived from a pre-immunized antibody phage display library system [PDF]

, 2002
The production and characterization of recombinant antibodies to aflatoxin B[SUB1] (AFB[SUB1]), a potent mycotoxin and carcinogen is described. The antibody fragments produced were then applied for use in a surface plasmon resonance-based biosensor ...

Augmenting the Effectiveness of CAR-T Cells by Enhanced Self-Delivery of PD-1-Neutralizing scFv

Frontiers in Cell and Developmental Biology, 2020
Chimeric antigen receptor T (CAR-T) cell therapy is not satisfying in solid tumors. PD-1-mediated suppression greatly hinders CAR-T cells in the microenvironment. It has been shown that PD-1 blockade improves the effectiveness of CAR-T cells.

Seed-produced anti-globulin VHH-Fc antibodies retrieve globulin precursors in the insoluble fraction and modulate the Arabidopsis thaliana seed subcellular morphology [PDF]

, 2020
Key message Nanobody-heavy chain (VHH-Fc) antibody formats have the potential to immunomodulate even highly accumulating proteins and provide a valuable tool to experimentally modulate the subcellular distribution of seed storage proteins.

Selection, alkaline phosphatase fusion, and application of single-chain variable fragment (scFv) specific to NT-proBNP as electrochemical immunosensor for heart failure

Heliyon, 2023
Heart failure has a high global prevalence, with symptoms such as breathlessness, fatigue, and swelling. Early detection is crucial, as the condition worsens over time and can be fatal. This study identified the single-chain variable fragment (scFv) that
