TAILORED TETRAVALENT ANTIBODIES POTENTLY AND SPECIFICALLY ACTIVATE WNT/FRIZZLED PATHWAYS IN CELLS, ORGANOIDS AND MICE

Tailored tetravalent antibodies potently and specifically activate Wnt/Frizzled pathways in cells, organoids and mice

Secreted Wnt proteins regulate development and adult tissue homeostasis by binding and activating cell-surface Frizzled receptors and co-receptors including LRP5/6.The hydrophobicity of Wnt proteins has complicated their purification and limited their use in basic research and as therapeutics.We describe modular tetravalent antibodies that can recr
