De novo protein design is becoming a powerful tool for diagnostic and therapeutic agent development. However, direct evidence remains lacking for dynamic binding of de novo designed binders both in vivo and clinical settings. PD-L1, quantified via immunohistochemistry, represents the most widely validated, utilized, and accepted biomarker for PD-1/PD-L1 therapy. Due to the spatial heterogeneity and temporal dynamics of PD-L1 expression, this molecule represents an ideal target for exploring the ...
