Free peptides have little or no resistance to cleavage by serum/tissue proteases, leading to poor stability and thus limiting their use as therapeutics. Protease recognition can be avoided by conjugation to a fragment crystallizable (Fc) domain of immunoglobulin G (IgG), generating a peptibody that exhibits higher circulation time than the stand‐alone peptide(s). The mechanism of action of peptibodies also mimics therapeutic antibodies ‐ they can act directly on cell membranes, killing the cells, or with membrane/soluble receptors, activating/disabling cellular pathways. Neves et al . discuss the design and production of peptibodies, and highlight a number currently in preclinical and clinical development. (doi: 10.1002/bip.23095 )
