Single domain shark VNAR antibodies neutralize SARS‐CoV‐2 infection in vitro [PDF]
FASEB Journal, 2021 Abstract Single domain shark VNAR antibodies can offer a viable alternative to conventional Ig-based monoclonal antibodies in treating COVID-19 disease during the current pandemic. Here we report the identification of neutralizing single domain VNAR antibodies selected against the SARS-CoV-2 spike protein derived from

The influence of antibody humanization on shark variable domain (VNAR) binding site ensembles
Frontiers in Immunology, 2022 Sharks and other cartilaginous fish produce new antigen receptor (IgNAR) antibodies, as key part of their humoral immune response and are the phylogenetically oldest living organisms that possess an immunoglobulin (Ig)-based adaptive immune system. IgNAR

Therapeutic Potential of Shark Anti-ICOSL VNAR Domains is Exemplified in a Murine Model of Autoimmune Non-Infectious Uveitis [PDF]
Frontiers in Immunology, 2017 Induced costimulatory ligand (ICOSL) plays an important role in the activation of T cells through its interaction with the inducible costimulator, ICOS. Suppression of full T cell activation can be achieved by blocking this interaction and has been shown

A novel shark VNAR antibody-based immunotoxin targeting TROP-2 for cancer therapy [PDF]
Acta Pharmaceutica Sinica BTROP-2, a tumor-associated antigen, has been implicated in the progression of various epithelial tumors. Due to its favorable expression profile, TROP-2 has emerged as a promising target for antibody-drug conjugates (ADCs) based anti-tumor therapies. Although ADCs have shown efficacy in cancer treatment, their application in solid tumors is hindered by
