Macrophage Trogocytosis of Tumor Cells Drives the Immunosuppression of Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
Trogocytosis efficiency varies significantly among different tumor cells and is inversely related to their cortical stiffness; this efficiency dictates the extent of immunosuppression via upregulation of CXCL5 and Arg‐1, ultimately driving CD8+T cell exhaustion and tumor escape.

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

open access: yesAdvanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.
