Development of [¹⁸F]FPy-WL12 as a PD-L1 Specific PET Imaging Peptide
Programmed death ligand 1 (PD-L1) is the principal ligand of the programmed death one (PD-1) receptor and is essential in the development of immune tolerance and prevention of autoimmunity. Unfortunately, PD-L1 is also expressed in many tumour types which is instrumental in allowing cancer cells to evade immune recognition. Immunohistochemistry may be used to
