CD200R1 immune checkpoint blockade by the first-in-human anti-CD200R1 antibody 23ME-00610: molecular mechanism and engineering of a surrogate antibody by Cristina Melero, S. Jimmy Budiardjo, Anahita Daruwalla, Lance Larrabee, Oleg Ganichkin, Alexander J. Heiler, Jill Fenaux, Ben Chung, Germaine Fuh, Yao-Ming Huang

“…Structural analysis suggests how the surrogate, named 23ME–00611, acquires the ortholog binding ability at the equivalent epitope of 23ME–00610. This engineering approach does not require a priori knowledge of structural and functional mapping of antibody–antigen interaction and thus is generally applicable for therapeutic antibody development when desired ortholog binding is lacking. …”
