Antibody fragment therapies are a type of biologic. They are typically fragments of monoclonal antibodies selected to bind to a particular protein (often a cell-surface protein), and produced using recombinant DNA technology.
Retinal vascular disease treatments involve frequent pharmacological intraocular administrations. Here the authors present a method to increase the half-life of injected drugs by fusing these to a hyaluronan-binding peptide, which might lead to less frequent retinal disease treatments.
Neutralizing antibodies for respiratory syncytial virus (RSV) can reduce disease in hospitalized children, but current options show limited efficacy. Here, the authors isolate potent single-domain antibodies from llamas that recognize the prefusion conformation of RSV F and prevent RSV replication in mice.
