Unlocking Multiple Biologic Therapeutic Avenues with 5T4 – A Solid Tumor Target

The 5T4 protein, also known as Wnt-activated inhibitory factor 1 (WAIF1) or Trophoblast Glycoprotein (TPBG), is a glycoprotein found in embryonic trophoblast cells. It has been identified as a treatment target for solid tumors due to its abundance in cancerous tissues and limited expression in normal tissues. Currently, there are approximately nine investigational drugs targeting […]

Unlocking the Secrets of Antibody-Drug Conjugates: Inside the World of Antibody Internalization

Antibody-drug conjugates (ADCs) mainly consist of monoclonal antibodies, linkers, and cytotoxic payloads. The antibody, acting as the “missile” in ADC drugs, possesses target-specific functionality. It can selectively recognize tumor cell surface antigens, undergo internalization upon binding to these antigens, and deliver the cytotoxic payload to tumor cells to exert its toxic effects. Since not all […]
