Despite the popular use of dietary supplements during conventional cancer treatments, their impacts on the efficacies of prevalent immunotherapies, including immune-checkpoint therapy (ICT), are unknown. Surprisingly, our analyses of electronic health records revealed that ICT-treated patients with cancer who took vitamin E (VitE) had significantly improved survival. In mouse models, VitE increased ICT antitumor efficacy, which depended on dendritic cells (DC). VitE entered DCs via the SCARB1 receptor and restored tumor-associated DC functionality by directly binding to and inhibiting protein tyrosine phosphatase SHP1, a DC-intrinsic checkpoint. SHP1 inhibition, genetically or by VitE treatment, enhanced tumor antigen cross-presentation by DCs and DC-derived extracellular vesicles (DC-EV), triggering systemic antigen-specific T-cell antitumor immunity. Combining VitE with DC-recruiting cancer vaccines or immunogenic chemotherapies greatly boosted ICT efficacy in animals. Therefore, combining VitE supplement or SHP1-inhibited DCs/DC-EVs with DC-enrichment therapies could substantially augment T-cell antitumor immunity and enhance the efficacy of cancer immunotherapies.

View all literature mentionsHelios, a CyTOF system, comprises the most recent advances in mass cytometry and is designed to provide a new and improved tool for bioanalytical single-cell detection and analysis. This high-performance mass cytometer, from the CyTOF family of instruments, enables the analysis of more than 40 markers and ly allows their quantitative determination with negligible spectral overlap, a result of exquisite resolution between mass detection channels. Helios provides users with 135 detection channels that can simultaneously resolve multiple elemental probes at high acquisition rates, thereby maximizing the per-cell information obtained from a single sample. The expanded mass range of 75 209 amu and superior mass resolution provide researchers with the ability to differentiate adjacent peaks. The Helios system provides fast instrument startup, an easyto-use pneumatic sample loading system, an improved cell detection rate, and enhanced data storage capabilities. These attributes provide researchers with an unparalleled ability to generate high-resolution phenotypic and functional profiles of cells from normal and diseased states.
