WebSep 9, 2024 · One trial applies a so-called chimeric switch receptor (CSR), consisting of PD1 as extracellular domain and CD28 transmembrane and intracellular signaling domain (Figure 6). As tumors often express PD-L1 on their surface to activate the inhibitory PD1 receptor on T cells to circumvent/inhibit an anti-tumor T-cell response, the CSR will turn … WebSep 9, 2024 · Another approach is based on the use of chimeric costimulatory switch receptor (CSR) based on the exodomain of coinhibitory receptors and the endodomain of costimulatory ones . We and others demonstrated that CSRs based on PD1 can enhance T-cell function in the presence of inhibitory ligands expressed by tumors cells [ 28 , 29 ].
