Trackable Tolerogenic Macrophages Integrate PD‐L1 and Rapamycin Signaling to Suppress Alloimmune Responses in Transplantation

Advanced Science, EarlyView.
We developed a macrophage‐based therapeutic platform, termed trackable tolerogenic macrophages (TTM), for dual‐function immunomodulation and visualization in vivo. TTM cells were engineered to overexpress PD‐L1, incorporate bioorthogonal cell surface tags, and load rapamycin for sustained release.

Non‐Volatile Phase Modulation with Ultralow Energy Consumption Enabled by 2D Ferroelectric/TMD Heterostructures

Advanced Science, EarlyView.
We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...
