Isolating T cells enriched in neoantigen reactivity prior to <i>in vitro</i> expansion and reinfusion may improve the response rates. To this end, our proprietary Specific Neo-Antigen Peptides (SNAP™) technology platform improves the accuracy of neoantigen prediction and validation by combining advanced computational modelling and PepSeq, a high-throughput screen for the physical credentialing of putative neoantigens based on their affinity to bind patient-specific HLA class II proteins. This approach allows for the education and enrichment of TILs (SNAP-TILs) with personalized, predefined, highly immunogenic neoantigens prior to expansion. Using the SNAP platform, we consistently achieved, on average, a SNAP-TIL product comprising 96% CD3+ cells, with a mixture of 75% effector and 23% central memory cells. SNAP-TILs exhibited greater efficacy and selectivity in immune infiltration than TIL, which was expanded by the rapid expansion protocol alone using <i>ex vivo</i> models. SNAP-TIL was also reactive in highly and poorly immunogenic tumors, with 70% and 50% tumor growth inhibition in melanoma and pancreatic patient-derived xenograft models, respectively.

To address these limitations, we previously developed an adapter CAR (AdCAR) platform that enables transient and combinatorial targeting to improve the safety and efficacy of CAR-T-cell therapy in AML. In this study, we further optimized the AdCAR system by investigating the role of immune checkpoint receptors (ICRs), particularly PD-1, CD96, LAG-3, TIM-3, and TIGIT, as well as the immunomodulatory molecule CD276, in suppressing AdCAR-T-cell function. Using multiparametric flow cytometry, we analyzed the expression of immune checkpoint ligands (ICLs) across multiple cancer entities, including three well-characterized AML cell lines, primary AML bone marrow samples, and healthy bone marrow as a reference. We then examined the inducibility of ICLs on AML cells after AdCAR-T-cell engagement. To evaluate the functional impact of immune checkpoint inhibition (ICI), we generated AdCAR-T-cells with CRISPR/Cas9-mediated knockouts (KOs) of PD-1, CD96, CD276, LAG-3, TIM-3, or TIGIT, and analyzed their cytotoxic potential in vitro. In our setting, PD-1 disruption did not significantly enhance AdCAR-T cytotoxicity against MOLM-13 wildtype, while TIGIT KO significantly enhanced AdCAR-T cytotoxicity specifically across five leukemia- and lymphoma-cell lines. Notably, pharmacological PD-1 blockade resulted in greater cytotoxicity than PD-1 gene disruption, whereas TIGIT blockade showed comparable effects to TIGIT KO.

IL-1R8, which is mostly expressed in a number of cell types, negatively regulates both IL-1R/TLR signaling, blocking the NF-kB/JNK pathway and the production of pro-inflammatory cytokines. Owing to its ability to inhibit both innate and adaptive immunity, IL-37 has been reported to control inflammation in many chronic disorders, including cancer. IL-37 impairs the proliferation and migration of tumor cells, mediates anti-angiogenetic mechanisms, and favors immunoregulation in the tumor microenvironment (TME). This review aims to provide a current overview of IL-37 genetic and biological features and of its active interaction with IL-1R8, inducing anti-inflammatory effects on the immune system and affecting cancer cell dynamics in the TME. Moreover, it analyzes the rare pro-tumoral effects of IL-37 in some tumors and discusses their possible mechanisms.
