Development of an 18 F-labeled anti-human CD8 VHH for same-day immunoPET imaging.
Eur J Nucl Med Mol Imaging, 50:679-691, 2023

PubMed Abstract: Cancer immunotherapies (CITs) have revolutionized the treatment of certain cancers, but many patients fail to respond or relapse from current therapies, prompting the need for new CIT agents. CD8 T cells play a central role in the activity of many CITs, and thus, the rapid imaging of CD8 cells could provide a critical biomarker for new CIT agents. However, existing Zr-labeled CD8 PET imaging reagents exhibit a long circulatory half-life and high radiation burden that limit potential applications such as same-day and longitudinal imaging.
