CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

open access: yesAdvanced Science, EarlyView.
A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

open access: yesHepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

The CSI multimedia architecture

open access: yesIEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2005
An instruction set extension designed to accelerate multimedia applications is presented and evaluated. In the proposed complex streamed instruction (CSI) set, a single instruction can process vector data streams of arbitrary length and stride and combines complex memory accesses (with implicit prefetching), program control for vector sectioning, and ...

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

open access: yesAdvanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

Balancing Crystallization Kinetics and Lattice Strain Enables Thermally Stable Slot‐Die‐Coated Narrow‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic

Polarity‐Controlled Coexistence of Electrochemical Metallization and Valence Change Mechanisms in a Unified Metal Halide Perovskite Memristor

open access: yesAdvanced Science, EarlyView.
Electrochemical metallization and valence change mechanisms are shown to coexist within a single metal halide perovskite memristor, selectively activated by simply reversing the electroforming voltage polarity. Ag‐driven switching delivers low operating voltages and high endurance, while intrinsic ion migration yields superior retention and resistance ...
